Low Battery Trip Volt:

The Low Battery Trip Volt is set at 10.0 VDC by default.It can be customized to 10.5VDC

AC Input Range:

There are different acceptable AC input ranges for different kinds of loads.It can be customized from 184-253VAC to 154-253VAC.

Load Sensing Cycle:

The inverter is factory defaulted to detect load for 250ms in every 30 seconds.This cycle can be customized to 3 seconds thru the SW3 on DIP switch.

Frequency adjust:

The frequency of the inverter is arranged by the Sw4.

The factory default configuration for 220/230/240VAC inverter is 05Hz,and 60Hz for 100/110/120VAC inverter.While the output freq can be easily changed once a qualified freq is applied to the inverter.

Solar/AC Priority Setting:

Our inverter is designed AC priority by default.This means,when AC input is present,the battery will be charged first,and the inverter will transfer the input AC to power the load.

 The AC Priority and Battery Priority switch is available upon request.When you choose battery pirority,the inverter will inverting from battery despite the AC input.
