Morningstar SunSaver SS20L 20A Solar Controller
The SunSaver is a sophisticated controller using advanced pulse width modulated regulation. PWM controllers maintain a higher state of charge in the battery bank than old-fashioned on-off regulators. This 20A model is suitable for photovoltaic systems up to 280W (560W for the 24V model).
With an anodised aluminium casing, marine-grade materials for the terminal block and epoxy encapsulated electronics, SunSavers can be mounted virtually anywhere. In the very unlikely event of a failure, they carry a five year manufacturer's warranty.
The load terminals allow you to connect appliances up to 20A. The regulator will automatically cut the power if the batteries fall below 11.5V (23.0V for 24V model), and reconnect at 12.6V (25.2V for 24V model) preventing dangerous levels of discharge. Ideal for appliances such as fridges that tend to be left on.
- High efficiency PWM charging
- Battery type selection
- LED indicators monitor battery voltage state
- Temperature compensation
- Electronic protection: over charging & discharging, overload, and short circuit
- Battery reverse polarity protection
- Marine rated terminals, epoxy encapsulated with an anodised aluminium case
- Self-consumption: < 8mA
Connections to the SunSaver regulators can be made using only bare wire, but for a more professional finish you may wish to use fork terminals. We can also make up complete cables to your specification - see the cables and connectors page.
Available in both 12V and 24V versions - see the options menu above.
