Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPTontoller will improve energy harvest by up to 30% compared to PWM charge contrllrs and by up to 10% compared to slower MPPT controllers.

Battery Life:
intelligent battery management
When a solar charge contoller 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 arially 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 slightlyincrease the load disconnect level (i.e. disconnect the load earlier)until the harvested solar energy isufficient 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.
Load output
Over-discharge of the battery can be prevented by connecting all loads to the load output. The load outputwill disconnect the load when the battery has been discharged to a pre-set voltage.
Alternatively, an ieleligent 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 remotecontrol connected to the load output. A special.
interface cable may be needed, please see the manual.

Maximum Power Point Tracking
Upper curve:
Output current (I) of a solar panel as function of output voltage M.
The maximum power point (MPP) is the point
Pmax along the curve where the product I × V reaches its peak .
Lower curve:
■Output power P=1xV as function of output voltage.
When using a PWM (not MPPT) controller the output voltage of the solar panel will be nearly equal to the voltage of the battery, and will belower than Vmp.
