Allow at least 12 inches of clearance around the inverter for air flow. Make sure that the air can circulate

freely around the unit.

Low Battery Trip Volt (SW1)

Deep discharge of the lead acid battery will cause losses in capacity and early aging. In some applications a

different low voltage disconnection level may be preferred. For example, in solar applications, users may

intend to have less DOD to prolong the battery life cycle. While for mobile applications, users may intend to

have more DOD to fully use the battery capacity available, minimizing on- board weight.

For 12VDC models, the Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to

10.5VDC using SW1. This is to prevent batteries from over-discharging while there is only a small load

applied on the inverter.

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 184-253VAC (100-135V for

120VAC model) is required to protect them.

While for some resistive loads that work in a wide voltage range, the input AC range can be customized to

154-264VAC (90-135V for 120VAC model). This helps to power loads with the most AC input power

without frequently switching to the battery bank.
