DIP
Switches
On the rear panel of inverter, there are 5 DIP switches which enable users to customize the performance of
the device.

SW1:Low Battery Trip Volt:
For 12VDC model, the Low Battery Trip Volt is set at 10.0Vdc by typical deep cycle lead acid battery. It
can be customized to 10.5Vdc using SW1 for sealed car battery, this is to prevent batteries from
over-discharging while there is only a small load applied on the inverter.(*2 for 24VDC, *4 for 48VDC)
SW2:AC Input Range:
There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100-135V for
120VAC model) is required to protect them.
While for some resistive loads which work in a wide voltage range, the input AC range can be customized to
154-253VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power
without frequent switches to the battery bank.
Power Saver Auto Setting :
The inverter is factory defaulted to detect load for 250ms in every 5 seconds. This cycle can be customized
to 3 seconds thru the SW3 on the DIP switch.
Solar/AC Priority:
Our inverter is designed with 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. Only when the AC input is
stable for a continuous period of 15 days, the inverter will start a battery inverting cycle to protect the
battery. After 1 cycle normal charging and ac through put will be restored.
The AC Priority and Battery Priority switch is SW4. When you choose battery priority, the inverter will
inverting from battery despite the AC input. Only when the battery voltage is reaches low voltage alarm
point(10.5V for 12V), the inverter transfers to AC Input, charges battery, and switches back to battery when
battery is charged full. This function is mainly for wind/solar systems taking utility power as back up.
