Over voltage protection indicator: (OVP)
The over voltage indicator indicates that the power inverter has shut itself down because its input voltage exceed-
ed the maximum input voltage.
17.8
Under voltage protection indicator: (UVP)
The under voltage indicator indicates that the power inverter has shut itself down because its input voltage fell
below minimum input voltage.
17.9
Over temp protection indicator: (OTP)
The over temp indicator indicates that the power inverter has shut itself down because its temp has become over-
heated. The power inverter may overheat because it has been operated at power levels above its rating, or be-
cause 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.
17.10 Overload protection indicator: (OLP)
The overload indicator indicates that the power inverter has shut down. A manual reset is necessary (switch it
OFF and ON again) to restart operation. This is a safety function to protect your battery when the inverter oper-
ates in a remote area.
