Low Battery Trip Volt:
The Low Battery Trip Volt is set at 10.0VDC 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.
AC/Battery Priority:
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 priority, the
inverter will inverting from battery despite the AC input.
2.5.13 Other features
Battery voltage recover start
After low battery voltage shut off(10V for 12V model), the inverter is able to restore to work after the
battery voltage recovers to 13V.
WARNING
Never leave the loads unattended, some loads (like a Heater) may cause accident in such cases.
