48V models. From 600Watts up to 3000Watts.
I-2. Battery voltage indicator :
The battery voltage bar graph indicates the voltage at the input
terminals of the power inverter at low input current, this voltage is
very close to the battery voltage. At high input current, this voltage
will be lower than the battery voltage because of the voltage drop
across the cable and connections. Ideally, the voltage should
remain in the green Ares of the bar graph. If the voltage goes into
the red area at top and bottom of the graph, inverter may shut –
down.
I-3. Load watt indicator
The AC load watt bar graph indicates the power drawn from the
power inverter. It will indicate watt by loads. For long term
operation , the watt should in the green & orange area of the bar
graph. Short-term operation is possible with watt in the red area. If
the watt rises to the flash all bar, the inverter will protect itself.
I-4. Over voltage indicator :
The over voltage indicator indicates that the power inverter has
shut itself Down because its input voltage has been over detect
voltage 12 / 24V / 48VDC version.
I-5. Under voltage indicator :
The under voltage indicator indicates that the power inverter has
shut itself Down because its input voltage has been low than
detect voltage 12 / 24V / 48VDC.
