2-7-8 Over Voltage Protection indicator: (OVP)
The over voltage indicator indicates that the power inverter has shut itself down
because its input voltage exceeded 12V / 24V / 48VDC version. (Ref. point 2-7-1)
2-7-9 Under Voltage Protection indicator: (UVP)
The under voltage indicator indicates that the power inverter has shut itself down
because its input voltage fell below 12V / 24V / 48VDC. (Ref. point 2-7-1)
2-7-10 Over Temp Protection indicator: (OTP)
The over temp indicator indicates that the power inverter has shut itself down
because its temperature has become overheated. The power inverter may
overheat because it has been operated at power levels above its rating, or
because it has been installed in a location which does not allow it to dissipate heat
properly. The power inverter will automatically back up, once it has cooled off.
2-7-11 Over Load Protection indicator: (OLP)
The overload indicator indicates that the power inverter has shut itself down.
When output voltage over its continuous voltage, then must return to operate
manually.
2-8 Cooling Fan Working Code
Cooling fan of inverter is through detecting output power and over temperature situation
to work.
When start to turn on the inverter and output power under 300W, the cooling fan does not
start running. It complies with saving energy sources requirement. Until, output power is
up to 300W, the cooling fan will start to work in order to drop the inner temperature.
If the ventilation opening is obstructed, the inverter will enter Over Temperature Protection
mode (OTP). The cooling fan will continue working to drop the inner temperature. When
the temperature comes down to normal situation, the inverter will turn on automatically.
