1 General Description
1.1 Ultra fast MPPT tracking
Especially in case of a clouded sky, when light intensity is changing continuously, a fast
MPPT algorithm will improve energy harvest by up to 30% compared to PWM charge
controllers and by up to 10% compared to slower MPPT controllers.
1.2 Load output
Over-discharge of the battery can be prevented by connecting all loads to the load
output. The load output will disconnect the load when the battery has been discharged
to a pre-set voltage.
Alternatively, an intelligent battery management algorithm can be chosen: see Battery
Life.
The load output is short circuit proof.
Some loads (especially inverters) can best be connected directly to the battery, and the
inverter remote control connected to the load output. A special interface cable may be
needed, please see section 3.6.
1.3 Battery Life: intelligent battery management
When a solar charge controller is not able to recharge the battery to its full capacity
within one day, the result is often that the battery will continually be cycled between a
‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no
regular full recharge) will destroy a lead-acid battery within weeks or months.
The Battery Life algorithm will monitor the state of charge of the battery and, if needed,
day by day slightly increase the load disconnect level (i.e. disconnect the load earlier)
until the harvested solar energy is sufficient to recharge the battery to nearly the full
100%. From that point onwards the load disconnect level will be modulated so that a
nearly 100% recharge is achieved about once every week.
1.4 Internal temperature sensor
Compensates absorption and float charge voltages for temperature.

1.5 Automatic battery voltage recognition
The controller will automatically adjust itself to a 12V or a 24V system.
1.6 Three step charging
The controller is configured for a three step charging process: Bulk – Absorption - Float.
1.6.1. Bulk stage
During this stage the controller delivers as much charge current as possible to rapidly
recharge the batteries.
1.6.2. 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 1A.
1.6.3. Float stage
During this stage, float voltage is applied to the battery to maintain a fully charged state.
When battery voltage drops below 13,2 Volt during at least 1 minute a new charge cycle will
be triggered.
1.6.4. Equalization
See section 3.8.1
1.7 Monitoring and configuring options

2. IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains important instructions that
shall be followed during installation and maintenance.
● It is advised to read this manual carefully before the product is installed and put into
use.
● This product is designed and tested in accordance with international standards. The
equipment should be used for the designated application only.
● Install the product in a heatproof environment. Ensure therefore that there are no
chemicals, plastic parts, curtains or other textiles, etc. in the immediate vicinity of the
equipment.
● The product is not allowed to be mounted in a user accessible area.
● Ensure that the equipment is used under the correct operating conditions. Never
operate it in a wet environment.
● Never use the product at sites where gas or dust explosions could occur.
● Ensure that there is always sufficient free space around the product for ventilation.
● Refer to the specifications provided by the manufacturer of the battery to ensure that
the battery is suitable for use with this product. The battery manufacturer's safety
instructions should always be observed.
● Protect the solar modules from incident light during installation, e.g. cover them.
● Never touch uninsulated cable ends.
● Use only insulated tools.
● Connections must always be made in the sequence described in section 3.5.
● The installer of the product must provide a means for cable strain relief to prevent the
transmission of stress to the connections.
●In addition to this manual, the system operation or service manual must include a battery
maintance manual applicable to the type of batteries used.
