3.0 INSTALLATION

3.1 General Installation Notes

• Read through the entire installation section first
before beginning installation.

• 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.

• F

or good service life, extreme temperatures and

marine environments should be avoided.

WARNING: Solar and battery fuses or DC
breakers are required in the system. These

protection devices are external to the EcoPulse
controller, and must be a maximum of 15
Amps for the EcoPulse-10/M, 30 Amps for
the EcoPulse-20/M, and 40 Amps for the
EcoPulse-30/M.

WARNING: All breakers must be properly rated
for wire ampacity, which may require less than
the maximum breaker sizes referenced above.

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

for 12V systems, and 4000A for 24V systems.

NOTE: Carefully observe the LEDs after
each connection. The LEDs will indcate
proper polarity, and a secure co nnection.

3.2 Configuration

The DIP switch block shown below is used to set the
operating parameters for the EcoPulse.

Switch 1: Lighting Control

With DIP 1 ON, a light connected to the load
terminals will be ON from dusk-dawn.

Switches 2, 3: System Voltage

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

System Voltage Switch 2 Switch 3

Switch 7: Battery Equalization

Mode Switch 7

Manual Equalization OFF

Auto Equalization ON

NOTE: Regardless of DIP 7 setting, manual EQ can be initiated using
the on-board meter command, "Start Equalize". For non-meter
versions, DIP 7 only enables or disables auto equalization - manual EQ

is not available.

Switch 8: Current Switching

Mode Switch 8

PWM switching OFF

Slow switching ON

The default (PWM) switching setting (OFF / down) operates
at 300Hz. If load or system noise is an issue, DIP 8 can be set
(ON-up) for slow switching at 1Hz. Standard PWM switching is
recommended when system noise is not a problem.

3.3 Mounting

Inspect the controller for shipping damage. Mount
the EcoPulse to a vertical surface (4-#8 stainless steel
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).

Table 3.1. Battery charging settings for each selectable battery type

If the system voltage DIP 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 done only at start-up,
and the detected system voltage will never change
during operation. It is recommended to set DIPs 2
and 3 to the correct system voltage setting. Only use
the default auto-detect setting if the nominal system
voltage is not known.

Switches 4, 5, 6: Battery Type Selection

Preset EcoPulse 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. Consult the battery
manufacturer for optimal battery charge settings.

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 EcoPulse version being
installed.

STEP 2: Remote Temperature Sensor

WARNING: Risk of Fire.

If no Remote Temperature Sensor (RTS)

is connected, use the EcoPulse 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.

Connect the RTS to the 2-position terminal located
(see figure). There is no polarity, so the (+) or (-) can
be connected to either screw terminal.

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

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

STEP 3:

Grounding

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.

For safety, and effective lightning protection, it is
recommended, and may be locally required, that
the negative conductor of the charging system be
properly grounded. Use only one system earth

ground. For conductor sizing requirements, refer to
the U.S. National Electrical Code, or applicable local
regulations or code.

4.1 Battery Charging Information

4-Stage Charging

The EcoPulse has a 4-stage battery charging algorithm
for rapid, efficient, and safe battery charging. Figure
4-1 below, shows the sequence of stages.

Figure 4.1. EcoPulse Charging Algorithm

Bulk Charge Stage

During Bulk charging, the battery is not at 100% state
of charge and battery voltage has not yet charged to
the Absorption voltage set-point. The controller will
deliver 100% of available solar power to recharge the
battery.

VOLTAGE

TIME

Absorption Stage

When the battery has recharged to the Absorption
voltage set-point, constant voltage regulation is
used to maintain battery voltage at the Absorption
set-point.

Float Stage

After the battery is fully charged in the Absorption
stage, the EcoPulse reduces the battery voltage to
the Float voltage set-point. The purpose of float is to
protect the battery from long-term overcharge.

Equalization Stage

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 over-charging 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 too long, can be damaging.
Review the requirements for the particular
battery being used in your system.

Equalization (EQ) charging raises the battery voltage
above the standard absorption voltage so that the
electrolyte gases.
