Explore the common error codes for Pure Sine Wave (ISW) inverters.
Error codes are determined by the led conditions on the front of the inverter or the ones shown on the GP-ISW-R remote.
There are three Led's on the front of the unit each will indicate a different type of error. Th middle led is for ac output and will go red if pulling more than the rated power of the inverter.
Status Light
Battery Voltage Warning
GP-ISW-R
• OVP (Over voltage protection):
• Indicates that the inverter will shut down because its input voltage is above
the voltage limit.
• UVP (Under voltage protection):
• Indicates that inverter will shut down because its input voltage is below the
voltage minimum.
• OLP (Overload protection indicator):
• Indicates the inverter will shut down due to a short circuit or overload protection.
• OTP (Over temperature protection indicator):
• Indicates the inverter will shut down due to over temperature protection. Once
the inverter cools down, the indicator will turn off automatically.
• INV indicator:
• Indicates the inverter is ready.
• PWR. SAV. indicator:
• Power saving functions are described below:

• GRID indicator:
Indicates the AC Grid is connected to the inverter (only functional when
connecting inverter series with Transfer Relay).
