Hey Donald, thanks for reaching out!

According to the instructions of the Go Power Industrial Pure Sine Wave Inverter Charger # 34280055, the OVP and red blinking you're getting means that the Inverter has the Over Voltage Protection status.

The max voltage for the inverter is 14.5V DC, so what you have going on is too much voltage running to the system. I'm guessing you may have rewired the batteries back incorrectly so you're seeing 24V instead of 12V.

Do you have multiple batteries, and how did you link them together?

@DonaldS Thanks! I reached out to my contact at Go Power and they sent me a lot of information. I'm going to copy and paste it below so you can see what they have to say, and start going through the troubleshooting steps: The OVP code typically means the inverter is detecting a battery voltage that is too high, even though your customer's reading is showing only 13V at the input. What kind of batteries are installed are they Lithium? It could be that the BMS switch is opening up and not allowing a charge. Was the measurement that was taken done at the back of the inverter? I would recommend starting with a hard reset of the unit. After that here are some other things to things to check and try: Double-check the actual battery voltage at the inverter terminals—sometimes there might be a difference between the measured voltage at the battery and at the inverter due to wiring or connection issues. Power cycle the inverter: Unplug from shore power. Turn off all loads. Power cycle the inverter by turning it off and then back on. Re-apply shore power and see if the code clears. Check charge settings on all sources: If there are any other devices charging the battery (like solar controllers or converters), verify that their charge settings are not too high, as this can trigger the OVP protection. Run the inverter without shore power: Let the inverter operate on battery only for a bit, which may help drop any residual high voltage and clear the code. Inspect battery type compatibility: If your customer is using lithium batteries, some lower-cost lithium battery brands may disconnect under brief voltage spikes, which can cause the inverter to see a momentary overvoltage and trigger OVP. In this case, using a higher quality lithium battery designed to handle the inverter’s ripple voltage is recommended. If the code persists after these steps, please let me know more about the battery brand and type, and if there are any other charging sources connected. That can help us narrow things down even further!
