Description:
Morningstar's SunSaver-20 is the world's leading small solar controller for both professional and consumer applications. The SunSaver is a sophisticated controller using advanced technology and series switching PWM charging. The battery charging process has been optimized for longer battery life and improved system performance. Because the SunSaver is a series controller, the PV current rating is specified at the PV array¿s peak power (Ipp). The SunSaver does NOT short the PV array for regulation, and it is not necessary to de-rate the controller for short-circuit current (Isc) as is commonly done with shunt controllers. SunSaver models with an automatic low voltage load disconnect function (LVD) are rated for either 6, 10 or 20 amp loads depending on the model. SunSaver models without an LVD capability are rated for a maximum load of 10 amps (if greater than 10A connect them directly to the batt
