SA31 & SA41 INVERTER FEATURES

Power
Designed for medium to large remote power systems, these inverters have enough power to start and run all household appliances.

Compatibility
To ensure your inverter will match pefectly to YOUR remote system, all important parameters of the SA31 or SA41 are adjustable via either the inverter front panel or the optional remote keypad.

Demand Start
In standby mode the inverter will turn on and off with any type of load, simply adjust the sensitivity to start the smallest load or overcome a phantom load. This feature will save you valuable battery power and may be overridden if necessary.

High & Low DC Voltage Cut Out
Low voltage and high voltage cut out are fully adjustable. Also a low voltage disconnect option can be selected to fully protect your batteries.

Safety & Reliability
Totally protected against thermal overload, current overload and AC short circuit. The AC output is electrically isolated for your safety, and is M.E.N. compatible. The on board computer monitors all operating parameters within the inverter to ensure trouble free operation. However, should service be required the modular construction allows for quick and easy on-site repairs by any authorised person.
