2.3 Optional Accessories

The following accessories are available for purchase
separately from your authorized Morningstar dealer:

Remote Temperature Sensor (Model: RTS)

The RTS measures battery temperature for accurate
temperature compensation and is recommended when
the ambient battery temperature differs from the ambient
controller temperature by more than 5º C. The standard
cable length is 33 ft (10m).

N

OTE: The use of a Remote Temperature Sensor is

strongly recommended. Controller location, air flow, and
system power can drastically affect the local temperature sensor
reading. An RTS will provide optimal charg

ing performance.

Ground-fault Protection Device (GFPD-150V)

As a safety measure, the GFPD-150V detects power source
ground faults and interrupts current.

3.1 General Installation Notes

• Read through the entire installation section first before

beginning installation.

• Be very careful when working with batteries. Wear

eye protection. Have fresh water available to wash
and clean any contact with battery acid.

• Use insulated tools and avoid placing metal objects

near the batteries.

3.0

• Do not install in locations where water can enter the
controller.

• Loose power connections and /or corroded wires
may result in resistive connections that melt wire
insulation, burn surrounding materials, or even cause
fire. Ensure tight connections and use cable clamps to
secure cables and prevent them from swaying in mobile
applications.

• Preset charging profiles are generally designed for
lead acid batteries. Custom settings can be used for
varied charging requirements (see sections 3.2 and 4.7
for details). Note that some battery types may not be
compatible.

• The EcoBoost MPPT battery connection may be wired
to one battery, or a bank of batteries. The following
instructions refer to a singular battery, but it is implied
that the battery connection can be made to either one
battery or a group of batteries in a battery bank.

• The EcoBoost MPPT uses self-tapping fasteners,
an anodized aluminum heat sink, and conformal
coating to protect it from harsh conditions. However,
for acceptable service life, extreme temperatures and
marine environments should be avoided.

• The EcoBoost MPPT prevents reverse current leakage at
night, so a blocking diode is not required in the system.

• The EcoBoost MPPT is designed to regulate ONLY solar
(photovoltaic) power. Connection to any other type of
power source e.g. wind turbine or generator may void
the warranty. However, other power sources can be
connected directly to the battery.

• The maximum power terminal wire size is #6 AWG /
16 mm

2

(solid/multi-strand) or #8 AWG / 10 mm2 (fine
strand). Use a flathead insulated screwdriver, and
torque tightly up to 3.95 Nm.

• Stranded wires to be connected to the EcoBoost MPPT
terminals should be prepared first with e.g. clamped
copper heads, etc. to avoid the possibility of one
conductor free out of the connection screw, and
possible contact with the metal enclosure.

WARNING: Solar and battery fuses or DC breakers

are required in the system. These protection devices
are external to the EcoBoost MPPT controller, and must be a
maximum of 25 amps for the EB-20/M, 35 amps for the EB­30/M, and 50 amps for the EB-40/M.

WARNING: Breakers and fuses may require lower
ratings than referenced above, so as not to exceed
any specific wire ampacity.

WARNING: Minimum over-current protection
device interrupt ratings must be 2000A for 12V

systems, and 4000A for 24V systems.

Switches 2, 3: System Voltage

Three (3) system voltage configurations are available as
shown in the table below:

System Voltage Switch 2 Switch 3

Auto OFF OFF

12 OFF ON
24 ON OFF

NOTE: Before connecting the battery, measure the open-circuit
voltage. It must be over 10 volts to start the controller. If the
system voltage Settings Switches are set to Auto-detect, battery
voltage over 15.5V will be detected as a 24V nominal battery,
and the unit will charge accordingly. The 12/24V auto selection is
only done at start-up, and the detected system voltage will never
change during operation.

Generally, the specfic system voltage is known, and it is best
to set DIPs 2,3 accordingly; the auto-detect setting should
be used only in rare circumstances.

Switches 4, 5, 6: Battery Type Selection

Preset EcoBoost MPPT battery charging options are shown
in table 3-1 below. All voltage settings listed are for nominal
12 volt batteries.

Multiply the voltage settings by two (2) for 24 volt systems.

NOTE: These settings are general guidelines for

use at the operator’s discretion. The
EcoBoost MPPT can be programmed to satisfy a wide range
of charging parameters.

Consult the battery manufacturer for

optimal battery charge settings.

3.3 Mounting

Inspect the controller for shipping damage. Mount the Eco­Boost MPPT to a vertical surface (4-#8 self-tapping screws
are included). Tighten the mounting screws, using care not
to crack the plastic case. Do not install directly over an easily
combustible surface since the heat sink may get hot under
certain operating conditions.

NOTE: The heat sink must be in a vertical position (fins

up and down).

For proper air flow, allow at least 15 cm (6 in) of space
above and below the controller, and 50 mm (2 in) at the
sides - see Figure 3-2 below. Install in an area protected
from direct rain and sun.

If the controller is installed in an enclosure, some
ventilation is recommended. Do not locate in an enclosure
where battery gases can accumulate.

3.4 Wiring

Figure 3-3. Wiring the EcoBoost MPPT

REFER TO FIGURE 3.3 WHEN USING THE WIRING INSTRUCTIONS
BELOW.

Installation

EcoBoost MPPT Operator’s Manual

1716

3.0

STEP 1: Check Controller Limitations

Verify that the highest temperature compensated solar array
open-circuit voltage (Voc), and load current do not exceed
the ratings of the EcoBoost MPPT version being installed.

Multiple controllers can be installed in parallel on the same
battery bank to achieve greater total charging current. In
this type of system, each EcoBoost MPPT must have its
own solar array. The load terminals of multiple controllers
can only be wired together if the total load draw does
not exceed the nameplate current of the LOWEST rated
controller.

STEP 2: Remote Temperature Sensor

WARNING: Risk of Fire.

If no Remote Temperature Sensor (RTS) is connected,
use the EcoBoost MPPT within 3m (10 ft) of the batteries. Internal
Temperature Compensation will be used if the RTS is not
connected. Use of the RTS is strongly recommended.

All charging settings are based on 25°C (77°F). If the
battery temperature varies by 5°C, the charging setting
will change by 0.15 Volts for a 12 Volt battery. This is a
substantial change in the charging of the battery, and the
use of the
optional Remote Temperature Sensor (RTS) is recommended
to adjust charging to the actual battery temperature. The
RTS can be added at any time after the system has been
installed.

Connect the (+) and (-) RTS wires to the 2-position terminal
located below the DIP switches (see figure 3.3).

The RTS is supplied with 10 m of 22 AWG (0.34 mm

2

) cable.
There is no polarity, so either wire (+ or -) can be connected
to either screw terminal. The RTS cable may be pulled
through conduit along with the power wires. Tighten the
connector screws to 0.56 Nm of torque. Separate installa­tion instructions are provided inside the RTS bag.

WARNING: Equipment Damage
Never place the temperature sensor inside a battery cell.
Both the RTS and the battery will be damaged.

CAUTION: The EcoBoost MPPT will use the local
temperature sensor for compensation if the RTS is not
used.

NOTE: The RTS cable may be shortened if the

full length is not needed. Be sure to reinstall the ferrite
choke on the end of the RTS if a length of cable is removed.
This choke ensures compliance with electromagnetic emissions
standards.

STEP 3: Grounding and Ground Fault Interruption

WARNING:

This unit is not provided with a GFDI device. This
charge controller must be used with an external GFDI
device as required by local regulations.

NOTE:

Depending on the country of installation, conductors
identified by the color green, or a combination
of green/yellow, shall only be used for earthing
conductors.

Use the M4 screw on the left side of the heatsink to attach
a grounding wire to the screw / heatsink, and connect the
wire to the earth ground. Also tie any dead metal to earth
ground.

WARNING: Risk of Fire

DO NOT bond the DC system electrical negative to
the EcoBoost MPPT heatsink / earth ground. If local
regulations require the use of a GFDI, the system
negative must be bonded through the GFDI to earth
ground at only one point.

Installation

EcoBoost MPPT Operator’s Manual

1918

3.0

Per IEC 62109, minimum sizes for equipment copper
grounding wire are:

• EcoBoost MPPT-20 10 mm

2

• EcoBoost MPPT-30 10 mm

2

• EcoBoost MPPT-40 10 mm

2

OR, of the same, or greater, cross-sectional area as the PV
wires.

For safety, and effective lightning protection, it is
recommended, and may be required by code, that the
negative conductor of the charging system be properly
grounded. Do not connect the negative conductor to the
heatsink equipment grounding teminal.

STEP 4: Battery Connections - see diagram below
Be sure that DIP switches 2 and 3 are set for 12 or 24V, as

described in Section 3.2

NOTE: Before connecting the battery, measure the open-circuit
voltage. It must be over 10 volts to start the controller. If the
system voltage Settings Switches are set to Auto-detect, battery
voltage over 15.5V will be detected as a 24V nominal battery, and
the unit will charge accordingly. The 12/24V auto selection is only
done at start-up.

With the battery disconnect open, connect the battery (+)
and (-) wires from the battery to controller. DO NOT CLOSE
THE BREAKER AT THIS TIME.

WARNING: Shock Hazard

The solar PV array can produce open-circuit voltages
in excess of 120 Vdc when in sunlight. Verify that the
solar input breaker or disconnect has been opened
(disconnected) before installing the system wires.

With the solar disconnect open, connect the solar (PV) array
wires to the EcoBoost MPPT solar terminals. Use caution,
since the solar array will produce current whenever in
sunlight. A solar disconnnect is a convenient way to break

the PV connection when necessary. DO NOT CLOSE THE
BREAKER AT THIS TIME.

STEP 7: Power-Up and Verify System Operation

NOTE: Carefully observe the LEDs after each

connection. The LEDs will indicate proper polarity and
a good connection.

Close the battery breaker to power on the controller. Watch
the the charging status, and then the three battery state­of-charge (SOC) LEDs blink in sequence (G-Y-R), confirm

­ing proper start-up. If they do not light, check the battery
polarity (+/–) and battery voltage.

Next, the green, yellow or red LED will light depending on
the battery state-of-charge (SOC). Confirm that one of these
LEDs is on before going to the next step.

Close the solar disconnect. If the solar input is connected
while in sunlight, the charging LED indicator will light.

Confirm proper connection by observing the charging LED.
Close the load disconnect, and turn the load on, to confirm

a proper connection.
If the load does not turn on, it could be for various reasons:

EcoBoost MPPT Operator's Manual

• the EcoBoost MPPT is in LVD (red LED on)

• there is a short circuit in the load (LEDs blinking R/G – Y)

• there is an overload condition (LEDs blinking R/Y - G)

• the load is not connected, not working, or turned off

After all connections have been completed, observe the
LEDs to make sure the controller is operating normally for
system conditions. If the optional digital meter is used,
observe that the display is scrolling with proper voltage
and current values. Also, a self- test can be performed with
digital meter units.

STEP 8: To Power-down

WARNING: Risk of Damage

ONLY disconnect the battery from the
EcoBoost MPPT AFTER the solar input has been
disconnected. Damage to the controller may result if the
battery is removed while the EcoBoost MPPT is charging.

• To prevent damage, power-down must be done in the
reverse order as power-up.

4.1 TrakStarTM MPPT Technology

The EcoBoost MPPT utilizes Morningstar’s TrakStar
Maximum Power Point Tracking technology to extract
maximum power from the solar module(s). The tracking
algorithm is fully automatic and does not require user
adjustment. TrakStar technology will track the array
maximum power point voltage (Vmp) as it varies with
weather conditions, ensuring that maximum power is
harvested from the array through the course of the day.

High Voltage Strings and Grid-tie Modules

Another benefit of TrakStar MPPT technology is the ability
to charge 12 or 24 Volt batteries with solar arrays of higher
nominal voltages. A 12 Volt battery bank can be charged
with a 12, 24, 36 or 48V nominal off-grid solar array.
Certain grid-tie solar modules may also be used if the solar
array open circuit voltage (V

oc

) rating will not exceed the
EcoBoost MPPT 120V maximum input voltage rating at
worst-case (lowest) module temperature. The solar module
documentation should provide V

oc

vs. temperature data.
Higher solar input voltage results in lower solar input current
for a given input power. High voltage solar input strings
allow for smaller gauge solar wiring. This is especially helpful
for systems with long wiring runs between the solar array
and the EcoBoost MPPT.

WARNING: Risk of Explosion

Equalizing vented batteries produces explosive gases.
The battery bank must be properly ventilated.

CAUTION: Equipment Damage

Equalization increases the battery voltage to levels that
may damage sensitive DC loads. Verify all system loads
are rated for the temperature compensated Equalize
voltage before beginning an Equalization charge.

CAUTION: Equipment Damage

Excessive overcharging and gasing too vigorously can
damage the battery plates and cause shedding of active
material from the plates. An equalization that is too
high or for too long can be damaging. Review the
requirements for the particular battery being used in
your system.

Battery Charge Settings

Preset EcoBoost MPPT battery charging options are shown
in tables 4-1 and 4-2 below. All voltage settings listed are
for nominal 12 Volt batteries. Multiply the voltage settings
by two (2) for 24 Volt batteries.

NOTE: These settings are general guidelines for
use at the operator’s discretion. The EcoBoost MPPT
can be programmed to satisfy a wide range of charging
parameters. Consult the battery manufacturer for optimal

battery charge settings.

4.3 Load Control Information

The primary purpose of the load control function is to
disconnect system loads when the battery has discharged to
a low state of charge, and to reconnect system loads when
the battery is sufficiently recharged. System loads may be
lights, DC appliances, or other electronic devices. The total
current draw of all loads must not exceed maximum load
ratings of 20 Amps (EB-20/M) or 30 Amps (EB- 30/M or EB­40/M).

CAUTION: Equipment Damage

Do not wire any AC inverter to the load terminals of the

EcoBoost. Damage to the load control circuit may result. An
inverter should be wired to the battery. If there is a possibility
that any other load will sometimes exceed the EcoBoost MPPT's
maximum voltage or current limits, the device should be wired
directly to the battery or battery bank. If load control is required,
contact Morningstar Tech Support for assistance.

Current Compensation:

All LVD and LVR set-points are current compensated.
Under load, the battery voltage will sag in proportion to the
current draw of the load. Without the current compensation
feature, a short-term large load could cause a premature
LVD. LVD and LVR set-points are adjusted lower per the
following table:

System Voltage

Current Compensation

12 Volt -15 mV per amp of load
24 Volt -30 mV per amp of load

Table 4-3. Current Compensation Values

LVD Warning:

As the battery discharges, the Battery Status LEDs will
transition from green to yellow and then from yellow to
flashing red. The flashing red indication is a warning that a
low voltage disconnect (LVD) event will occur soon.

The amount of time between a green SOC indication and
load disconnect will depend on many factors including:

• rate of discharge (amount of load draw)

• capacity of the battery

• health of the battery

• LVD set-point

If the battery discharges to the LVD set-point the load will
disconnect and a solid red Battery Status LED indication will
be displayed.

General Load Control Notes:

Do not wire multiple EcoBoost MPPT load outputs together
in parallel to power DC loads with a current draw greater
than 20 or 30A, depending on the EcoBoost MPPT model in
use. Equal current sharing cannot be assured and an over­load condition will likely occur on one or more controllers.

CAUTION: Equipment Damage

Exercise caution when connecting loads with
specific polarity to a live load circuit. A reverse polarity
connection may damage the load. Always double check
load connections before applying power.

Solar Overload

No LED indication. The EcoBoost MPPT will limit battery
current to the 20, 30 or 40 amp maximum rating. An over­sized solar array will not operate at peak power. The solar
array should be less than the EcoBoost MPPT nominal max.
input power rating for optimal performance. See Section

7.0 - Technical Specifications for more information.

High Temperature Current Limit

The EcoBoost MPPT will limit the solar input current if the
heatsink temperature exceeds safe limits. Solar charge
current will be tapered back (to 0 amps if needed) to reduce
the heatsink temperature. The EcoBoost MPPT is designed
to operate at full rated current at the maximum ambient
temperature. This alarm indicates that there is insufficient
airflow and that the heatsink temperature is approaching
unsafe limits. If the controller frequently reports this alarm
condition, corrective action must be taken to provide better
air flow or to re-locate the controller to a cooler spot.

High Input Voltage Current Limit

The EcoBoost MPPT will limit the solar input current as
the solar array Voc approaches the maximum input voltge
rating. The array Voc should never exceed the 120 volt
maximum input voltage - see the array voltage de-rating
graph in Appendix.

Current Limit

The array power exceeds the rating of the controller. This
alarm indicates that the EcoBoost MPPT is limiting battery
current to the maximum current rating.

RTS Open

The Remote Temperature Sensor is not connected to the
controller. Use of the RTS is recommended for proper
battery charging.

Heatsink Temperature Sensor Open / Shorted

The heatsink temperature sensor is damaged. Return the
controller to an authorized Morningstar dealer for service.

Uncalibrated

The controller was not factory calibrated. Return the
controller to an authorized Morningstar dealer for service.

4.6.2 Meter Display Operation

4.6.2.1 Directional Key Use and Operation / Navigating
the Meter Map

The EcoBoost MPPT's meter map consists of two main
axes: The horizontal top level daily monitoring screens, and
the vertical Main Menu stacked screens. The four lighted
triangular directional control keys allow movement to reach
any desired point on the meter map. A lit key indicates
a valid direction in the map. The current location is
indicated on the display with a column heading, and a bold
descriptor.

4.6.2.2 Adjusting the Meter Display

The display setting options, as shown in Figure 4-2, are
adjustable by using the directional keys to locate and edit a
desired setting or variable.

4.7 Data Logging (future use)

The EcoBoost MPPT logs thirty days of basic system data:

• Daily minimum battery voltage

• Daily maximum battery voltage

• Daily Events (Equalize triggered, Entered Float, Alarm/
Fault occurred, Reset)

• Faults / Alarms - recorded only if a fault or alarm occurs
that day

• Daily charge to battery

The EcoBoost MPPT USB Micro-B port (for future use) will
allow data transfer in mobile applications.

4.8 Auxilliary USB Charging

1) The EcoBoost MPPT has two USB-A ports for use as
charging sources for small electronics. Energy is taken from
the system battery, so any auxilliary charging must be bal­anced with other load draws on the system battery.

2) The USB charging ports will operate in all conditions
except for LVD, HVD, or a user requested Load Disconnect
(from a meter command, for example). In LVD, HVD & Load
Disconnect, the main load and the USB ports are powered
off.

3) If the main load gets faulted for some reason (shorted
FET, etc), the USB charging ports will still operate.

4.9 Inspection and Maintenance

Table 4-6 below lists the recommended maintenance
schedule to keep your EcoBoost MPPT performing
optimally.

5.1 LED Fault Indications

Load Over-current

Error Status LED: Flashing red. Battery status LEDs: R/Y­G sequencing. If the load current exceeds the maximum
load current rating, the EcoBoost MPPT will disconnect the
load. The greater the overload the faster the load will be
disconnected. A small overload could take a few minutes to
disconnect. The EcoBoost MPPT will attempt to reconnect
the load two (2) times. Each attempt is approximately 10
seconds apart. If the overload remains after two (2)
attempts, the load will remain disconnected until power is
removed and re-applied.

Solar Short Circuit

Charging Status LED: OFF. Solar input power wires are
short-circuited. Charging automatically resumes when the
short is cleared.

Battery Reverse Polarity

No LED indication, the unit is not powered. No damage to
the controller will result. Correct the miswire to resume
normal operation.

5.0 TROUBLESHOOTING

Troubleshooting

EcoBoost MPPT Operator’s Manual

5.0

Load Short Circuit

Error status LED: Flashing red. Battery status LEDs: R/G-Y
sequencing. Fully protected against load wiring short­circuits. After two (2) automatic load reconnect attempts (10
seconds between each attempt) the EcoBoost MPPT will
wait, and then automatically reconnect the load, once the
short is cleared.

High Solar Voltage Disconnect

Charging Status LED: R flashing. No battery status errors.
If the solar input open-circuit voltage (Voc) exceeds the 120
volt maximum rating, the array will remain disconnected
until the Voc falls safely below the maximum rating.

Remote Temperature Sensor (RTS)

Error status LED: Flashing red. Battery status LEDs: R/Y ­G/Y sequencing. A bad RTS connection or a severed RTS
wire has disconnected the temperature sensor during
charging. Charging automatically resumes when the
problem is fixed. To resume operation without an RTS,
disconnect all power to the EcoBoost MPPT and then
reconnect. If the controller is re-started with the failure
still present, the controller may not detect that the RTS is
connected, and the LEDs will not indicate a fault.
A metered model, an RM-1 meter, or MSView PC software
can be used to determine if the RTS is working properly.

Battery / Load High Voltage Disconnect (HVD)

Error status LED: Flashing red. Battery status LEDs: R-G
sequencing. This fault is set when battery voltage is above
normal operating limits. The controller will disconnect the
solar input and set a High Voltage Disconnect fault. This
fault is commonly caused by other charging sources in the
system, charging the battery above the EcoBoost MPPT
regulation voltage. Recovery occurs at HVD re-connect
threshold, and the fault will automatically clear. See Section
7 - Technical Specifications for values.

High Heatsink Temperature

Error status LED: Flashing red. Battery status LEDs: R-Y
sequencing. The heatsink temperature has exceeded safe
limits and the load is disconnected. The load will automati­cally reconnect when the heatsink cools to a safe
temperature.

Battery Over-current

Error status LED: Flashing red. Battery status LEDs:
R/Y-G sequencing. While rare, if battery current exceeds
approximately 130% of the controller’s output current
rating, this fault can occur. The fault is generally related
to fast, large battery voltage transients (connecting a very
heavy or capacitive load like an inverter) that are faster
than the controller can regulate, and it shuts off to protect
the circuitry. The controller will automatically re-start in 10
seconds.

Settings (DIP) Switch Changed

Error status LED: Flashing red. Battery status LEDs:
R-Y-G sequencing. If a settings switch is changed while
there is power to the controller, the LEDs will begin
sequencing and the solar input will disconnect. The
controller must be re-started to clear the fault and begin
operation with the new settings.

Custom Settings Edit
Error status LED: Flashing red. Battery status LEDs: R-Y-G

sequencing. A value has been modified in custom settings
memory. The controller will stop charging and indicate a
fault condition. After all settings have been modified, the
controller must be reset by removing and then restoring
power to the controller. The new programmed settings will
be used after the power reset.

Firmware Update Failure

The firmware update was not successfully programmed. The
controller will not indicate the full power-up LED sequence
of G-Y-R when power to the controller is reset. Instead, the

5.2 Battery Charging and Performance Issues

Problem:

No LED indications, controller does not appear to be
powered

Solution:

With a multi-meter, check the voltage at the battery
terminals on the EcoBoost MPPT. Battery voltage must be
10 vdc or greater. If the voltage on the battery terminals of
the controller is between 10 and 35 vdc, and no LEDs are lit,
contact your authorized Morningstar dealer for service.
If no voltage is measured, check wiring connections, fuses,
and breakers.

Problem:

The EcoBoost MPPT is not charging the battery.

Solution:

Check the three (3) battery SOC LEDs. If they are flashing in
a sequence, see Section 4.5 LED indications of this manual
to determine the cause. A metered model, an RM-1 meter,
or MSView PC software will display active faults and alarms.

If the LED indications are normal, check the fuses,
breakers, and wiring connections in the power source wiring.
With a multi-meter, check the array voltage directly at the
EcoBoost MPPT solar input terminals. Input voltage must be
greater than battery voltage before charging will begin.

Problem:

Controller makes buzzing and humming noises.

Solution:

No action is required. This is expected due to magnetic
resonance and circuit switching.

If troubleshooting does not correct the problem, please
refer to Morningstar's Warranty Claim Procedure in
Section 6.
