SL Series
SL Series
The SL power system is an inverter but also contains a powerful smart charger. It provide a pure sine wave power to all equipments.

The SL inverter is a heavy-duty, continuous working module generating a sinusoidal wave from a 12/24V - battery bank, which can supply energy to various loads such as resistive load (heater),inductive load (air conditioners, refrigerator),motors (vacuum cleaners), and rectifier load (computer). All SL series are designed to work in heavy load condition. Derating is not necessary. It provides a rapid and complete charging process.

The smart charger can be set with different charging profiles and battery capacities to match in various battery types and sizes. The switch module automatically diverts the energy transfer path between inverter and utility source. When the utility source is lower than the transfer level, the path switches to the inverter. Otherwise the load is conducted to the utility source. The transfer time is 1/4~1/2 of the total cycle time. The high power charger (40A) can charge a 24V/400 AH battery bank in 10 hours.

SL series is an extremely good choice for utility back up power. However, it also can be used as a UPS for computers.

An inverter, charger and switching box can be replaced with a single SL series unit.
