performance of the device. *Factory Default

Low Battery Trip Point (SW1):
Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In differ
-
ent applications a different low voltage disconnection level is preferred. For example, for applica
-
tions, user may intend to have less DOD to prolong the battery life cycle. While for mobile appli-
cations users may intend to have more DOD to reduce battery capacity and on board weight.
*2 for 24VDC, *4 for 48VDC
AC Input Range (SW2):
There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 100-135Vis 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 models, 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
position “1”, the inverter will bypass an AC input with a wider voltage and frequency (40Hz plus
for 50Hz/60Hz). Accordingly, the AC charger will also work in a wider voltage and freq range
(43Hz plus for 50Hz/60Hz).
This will avoid frequent switches between battery and generator. But some sensitive loads will
suffer from the low quality power.
The pros and cons should be clearly realized.
