Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can
circulate freely around the unit.

3.11 DIP SWITCHES & BTS
On the DC end of inverter, there are 3 DIP switches which enable users to customize the
performance of the device to suit the specific configuration.

Low Battery Trip Volt:
Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In different
applications, different low voltage disconnection level is preferred. For example, for solar application,
user intended to have less DOD to prolong the battery cycle life. While for mobile application, users
intend to have more DOD to reduce battery capacity and on board weight.
For 12VDC model, the Low Battery Trip Volt is set at 11.5VDC by default. It can be customized to
11.9VDC using SW1, this is to prevent batteries from over-discharging while there is only a small
load applied on the inverter.
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 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 90-135V for 120VAC model, this helps to power loads with the most AC input power
without frequent switches to the battery bank.
In order to make the inverter accept dirty power from a generator, when the SW2 is switched to
