Upsizing the PV array or regularly "downsizing" the load:
A load-acid battery will last even longer if a full recharge, including several hour absorption time, is achieved at least once every week.
The load output is short circuit proof and can supply loads with a large DC input capacitor such as an inverter (but it can't start a DC load and an inverter simultaneously).
Resin encapsulated electronics:
Protects the electronic components are against the environment.
Automatic battery voltage recognition:
The MPPT will automatically adjust itself to a 12V or a 24V system.
Maximum open circuit PV voltage:75V.
The controller can be used with any PV configuration that satisfies the three above mentioned conditions.
