List of Error Codes
Below are two tables that identify inverter error codes, and how to remedy them.
| Remote Error Codes | ||
| PTOC (Over current protection) | Pulling to much current from inverter | Turn off loads, unplug from shore power, power cycle the inverter. Turn inverter back on and re-apply shore power |
| OTP (Over Temperature Protection) | Inverter or batteries are to hot | Check battery connections. Is battery to hot? Remove temp sensor |
| UTP (under temperature Protection) | Inverter or batteries are to cold | Warm batteries up in some way |
| UVP (Under voltage protection) | Battery voltage is below Low voltage disconnect point on the inverter |
Recharge batteries above LVD set on inverter. Then turn inverter on and re-apply shore power |
| OOCP (Over current protection) | Second over current message | Turn off loads, unplug from shore power, power cycle the inverter. Turn inverter back on and re-apply shore power |
| OVP (Over voltage protection) | Battery volatge is to high | Unplug shore power power cycle the inverter. Run inverter without shore power to drop battery voltage. Check charge settings on all sources |
| Poff (NO ac power) | NO AC input power | Check breakers and AC getting to inverter |
| OLP Over Load protection | Loads to high for inverter output | Turn off loads, unplug from shore power, power cycle the inverter. Turn inverter back on and re-apply shore power. Turn loads on one by one eliminating load causing the issue |
| Error Beeps From Inverter | |
| Beeping counts | Protection signal |
| 1 beep | UTP (Under Temp Protection) |
| 2 beep | OTP (Over Temp Protection) |
| 3 beep | OVP |
| 4 beep | UVP |
| 5 beep | Short-circuit or OLP |
