2. DESCRIPTION
2.1 General
All-in-one solar power solution
The EasySolar combines a MPPT solar charge controller, an inverter/charger and AC
distribution in one enclosure.
The product is easy to install, with a minimum of wiring.
Solar charge controller: BlueSolar MPPT 100/50
Up to three strings of PV panels can be connected with three sets of MC4 (PV-ST01) PV
connectors.
Inverter/charger: MultiPlus Compact 12/1600/70 or 24/1600/40
The MPPT charge controller and the MultiPlus inverter/charger share the DC battery cables
(included). The batteries can be charged with solar power (MPPT) and/or with AC power
(inverter/charger) from the utility grid or a genset.
AC distribution
The AC distribution consists of a RCD (30mA/16A) and four AC outputs protected by two 10A
and two 16A circuit breakers.
One 16A output is controlled by the AC input: it will switch on only when AC is available.
PowerAssist
Unique PowerAssist technology protects the utility or generator supply from being overloaded
by adding extra inverter power when needed.

2.2 Inverter
MultiPlus Compact-functional
The MultiPlus Compact gets its name from the multiple functions it can perform. It is a
powerful true sine wave inverter, a sophisticated battery charger that features adaptive
charge technology and a high-speed AC transfer switch in a single compact enclosure.
Beside these primary functions, however, the MultiPlus Compact has several advanced
features that provide a range of new applications as outlined below.
Uninterrupted AC power
In the event of a grid failure, or shore or generator power being disconnected, the inverter
within the MultiPlus Compact is automatically activated and takes over supply to the
connected loads. This happens so fast (less than 20 milliseconds) that computers and
other electronic equipment will continue to operate without disruption.
PowerControl – Dealing with limited generator or shore side power
With a Multi Control Panel a maximum generator or shore current can be set. The
MultiPlus Compact will then take account of other AC loads and use whatever is extra for
charging, thus preventing the generator or shore supply from being overloaded.
PowerAssist – Boosting the capacity of shore or generator power
This feature takes the principle of PowerControl to a further dimension allowing the
MultiPlus Compact to supplement the capacity of the alternative source. Where peak
power is so often required only for a limited period, it is possible to reduce the size of
generator needed or conversely enable more to be achieved from the typically limited
shore connection. When the load reduces, the spare power is used to recharge the
battery.
Programmable relay
The MultiPlus is equipped with a programmable relay that by default is set as an alarm relay.
The relay can be programmed for all kinds of other applications however, for example as a
starter relay for a generator.
2.3 Battery Charger
Adaptive 4-stage charge characteristic: bulk – absorption – float – storage
The MultiPlus Compact features a microprocessor controlled ‘adaptive’ battery management
system that can be preset to suit different typs of batteries. The ‘adaptive’ feature will
automatically optimize the process relative to the way the battery is being used.
The right amount of charge: variable absorption time
When only shallow discharges occur (a yacht connected to shore power for example) the
absorption time is kept short in order to prevent overcharging of the battery. After a deep
discharge the absorption time is automatically increased to make sure that the battery is
completely recharged.

Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, the MultiPlus Compact will prevent damage due to
excessive gassing by automatically limiting the rate of voltage increase once the gassing
voltage has been reached.
Less maintenance and aging when the battery is not in use: the Storage mode
The storage mode kicks in whenever the battery has not been subjected to discharge during
24 hours. In the storage mode float voltage is reduced to 2,2V/cell (13,2V for a 12V battery) to
minimize gassing and corrosion of the positive plates. Once a week the voltage is raised back
to the absorption level to ‘equalize’ the battery. This feature prevents stratification of the
electrolyte and sulphation, a major cause of early battery failure.
To increase battery life: temperature compensation
Every MultiPlus Compact comes with a battery temperature sensor. When connected, charge
voltage will automatically decrease with increasing battery temperature. This feature is
especially recommended for sealed batteries and/or when important fluctuations of battery
temperature are expected.

2.4 Charge Controller MPPT 100/50
Charge current up to 50A and PV voltage up to 100V
The BlueSolar MPPT 100/50 charge controller is able to charge a lower nominal-voltage
battery from a higher nominal voltage PV array.
Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast
MPPT controller will improve energy harvest by up to 30% compared to PWM charge
controllers and by up to 10% compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the powervoltage curve.
Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP.
The innovative BlueSolar algorithm will always maximize energy harvest by locking to the
optimum MPP.
Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).
Flexible charge algorithm
Eight preprogrammed algorithms, selectable with a rotary switch.
Extensive electronic protection
Over-temperature protection and power derating when temperature is high.
4
PV short circuit and PV reverse polarity protection.
PV reverse current protection.
Internal temperature sensor
Compensates absorption and float charge voltages for temperature.
Adaptive three step charging
The BlueSolar MPPT Charge Controller is configured for a three step charging process:
Bulk – Absorption – Float.
Bulk stage
During this stage the controller delivers as much charge current as possible to rapidly
recharge the batteries.
Absorption stage
When the battery voltage reaches the absorption voltage setting, the controller switches
to constant voltage mode.
When only shallow discharges occur the absorption time is kept short in order to prevent
overcharging of the battery. After a deep discharge the absorption time is automatically
increased to make sure that the battery is completely recharged. Additionally, the
absorption period is also ended when the charge current decreases to less than 2A.
Float stage
During this stage, float voltage is applied to the battery to maintain it in a fully charged
state.
2.5 Configuration Assitants
Several software programs (Assistants) are available to configure the system for various grid
interactive or stand alone applications. Please see http://www.victronenergy.nl/support-and-
downloads/software/

Equalisation mode supplies a higher charging voltage than most DC consuming
charging takes place.
3. OPERATION – inverter/charger
3.1 On/Off/Charger Only Switch
When switched to ‘on’, the product is fully functional. The inverter will come into operation and
the LED ‘inverter on’ will light up.
An AC voltage connected to the ‘AC in’ terminal will be switched through to the ‘AC out’
terminal, if within specifications. The inverter will switch off, the ‘mains on’ LED will light up
and the charger commences charging. The ‘bulk’, ‘absorption’ or ‘float’ LEDs will light up,
depending on the charger mode.
If the voltage at the ‘AC-in’ terminal is not within specifications, the inverter will switch on.
When the switch is switched to ‘charger only’, only the battery charger of the MultiPlus will
operate (if mains voltage is present). In this mode input voltage also is switched through to the
‘AC out’ terminal.
NOTE: When only the charger function is required, ensure that the switch is switched to
‘charger only’. This prevents the inverter from being switched on if the mains voltage is lost,
thus preventing your batteries from running flat.
3.2 Remote control
Remote control is possible with a 3-way switch or with a Digital Multi Control panel.
The Control panel has a simple rotary knob with which the maximum current of the AC input
can be set: see PowerControl and PowerAssist in Section 2.
For the appropriate DIP switch settings, see sect. 5.5.1.
3.3 Equalisation and forced absorption
3.3.1 Equalisation
Traction batteries may require regular equalisation charging. In the equalisation mode, the
MultiPlus will charge with increased voltage for one hour (1V above the absorption voltage for
a 12V battery, 2V for a 24V battery). The charging current is then limited to 1/4 of the set
value. The ‘bulk’ and ‘absorption’ LEDs flash intermittently.
devices can cope with. These devices must be disconnected before additional
3.3.2 Forced absorption
Under certain circumstances, it can be desirable to charge the battery for a fixed time at
absorption voltage level. In Forced Absorption mode, the MultiPlus will charge at the normal
absorption voltage level during the set maximum absorption time. The ‘absorption’ LED will be
‘on’.
6
3.3.3 Activating equalisation or forced absorption
The MultiPlus can be put into both these states from the remote panel as well as with the
front panel switch, provided that all switches (front, remote and panel) are set to ‘on’ and
no switches are set to ‘charger only’.
In order to put the MultiPlus in this state, the procedure below should be followed.
If the switch is not in the required position after following this procedure, it can be
switched over quickly once. This will not change the charging state.
NOTE: Switching from ‘on’ to ‘charger only’ and vice versa, as described below, must be done quickly.
The switch must be toggled such that the intermediate position is 'skipped', as it were. If the switch
remains in the ‘off’ position even for a short time, the device may be turned off. In that case, the
procedure must be restarted at step 1. A certain degree of familiarisation is required when using the
front switch on the Compact in particular. When using the remote panel, this is less critical.
Procedure:
1. Check whether all switches (i.e. front switch, remote switch or remote panel switch if present) are in
the ‘on’ position.
2. Activating equalisation or forced absorption is only meaningful if the normal charging cycle is
completed (charger is in 'Float').
3. To activate:
a. Switch rapidly from ‘on’ to ‘charger only’ and leave the switch in this position for ½ to 2 seconds.
b. Switch rapidly back from ‘charger only’ to ‘on’ and leave the switch in this position for ½ to 2
seconds.
c. Switch once more rapidly from ‘on’ to ‘charger only’ and leave the switch in this position.
4. On the MultiPlus the three LEDs ‘Inverter’, ‘Charger’ and ‘Alarm’ will now flash 5 times.
If a MultiControl panel is connected, on the panel the LEDs ‘bulk’, ‘absorption’ and ‘float’ will also flash
5 times.
5. Subsequently, on the MultiPlus the LEDs ‘Bulk’, ‘Absorption’ and ‘Float’ will each light during 2
seconds.
If a MultiControl panel is connected, on the panel the LEDs ‘bulk’, ‘absorption’ and ‘float’ will also each
light during 2 seconds.
6.
a. If the switch on the MultiPlus is set to ‘on’ while the ‘Bulk’ LED lights, the charger will switch to
equalisation.
Similarly, if the switch on the MultiControl panel is set to ‘on’ while the ‘Bulk’ LED lights, the charger will
switch to equalisation.
b. If the switch on the MultiPlus is set to ‘on’ while the ‘Absorption’ LED lights, the charger will switch to
forced absorption.
Similarly, if the switch on the MultiControl panel is set to ‘on’ while the ‘Absorption’ LED lights, the charger
will switch to forced absorption.
c. If the switch on the MultiPlus is set to ‘on’ after the three LED sequence has finished, the charger will
switch to ‘Float’.
Similarly, if the switch on the MultiControl panel is set to ‘on’ after the three LED sequence has finished, the
charger will switch to ‘float’.
d. If the switch is has not been moved, the MultiPlus will remain in ‘charger only’ mode and switch to ‘Float’.
