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 BatteryLife: intelligent battery management
1.2.1. Conventional 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 be 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.
1.2.2. BatteryLife algorithm
The BatteryLife algorithm will monitor the state of charge of the battery and day by day
slightly increase the load disconnect level until absorption voltage is reached. From that
point onwards the load disconnect level will be modulated so that absorption voltage is
reached about once every week. The BatteryLife algorithm will substantially increase
service life of the battery when compared to 1.2.1.
1.2.3. Upsizing the PV array or regularly "downsizing" the load
A lead-acid battery will last even longer if a full recharge, including several hours
absorption time, is achieved at least once every week.
1.3 Load output
The load output is short circuit proof and can supply loads with a large DC input
capacitor such as an inverter (but it can not start a DC load and an inverter
simultaneously).
Alternatively, an inverter can be switched on and off by using the load output to switch the
remote on-off of the inverter (see section 3.6).
1.4 Internal temperature sensor
Compensates absorption and float charge voltages for temperature.
