On sunny days, Inverter switches off when DC voltage gets too high

I can see from the graphs available that this occurs when the batteries move from 99% to 100% charged and the inverter DC voltage, spikes from 2x 330v (=720v) to 2 x 387v (=774v). At other times of the day, when the battery reaches 100%, the DC voltage is not as high and the inverter does not switch off.

6. Troubleshooting and Support

High DC ripple is usually caused by loose DC cable connections and/or too thin DC wiring. After the inverter has switched off due to high DC ripple voltage, it waits 30 seconds and then restarts. After three restarts followed by a shutdown due to high DC ripple within 30 seconds of restarting, the inverter will shutdown and stops retrying.

6 FAQs about [Inverter AC voltage is too high]

What if my inverter voltage is too high?

If your inverters are operating in a different AC grid input mode your inverters shouldn't disconnect above 132V, but allow the higher voltage to pass through to your loads, up to whatever AC limit you've set. See this thread for more info: Re: Input Voltage is Too High... what to do? more info..

What causes a DC inverter to overvoltage?

This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.

What causes a solar inverter to fail?

The AC voltage overrange is the most common failure of the solar inverter connected with the PV grid system. This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage.

Why does my inverter display a grid overvoltage?

When the inverter is connected to the grid-connected voltage range, the inverter will display the grid overvoltage. In addition, the cable used by the inverter to the grid point is too long, too thin, entangled or the material is not in compliance, which will lead to an increase in the voltage difference at the AC terminal of the inverter.

Why isn't my inverter working?

If the voltage with the inverter off is much higher than 240, then a high line voltage from your utility is contributing to the problem. If it is close to 240, then check for a bad connection. The problem may go away on its own if you need to re-run it all in 4 AWG to meet code.

What if my inverter AC voltage is higher than 256v?

If it is indeed reaching 256V + in the middle of the day, and your inverter AC is not higher than 2% over the Feed in point voltage, then this is a complaint with your grid distributor. However if the inverter AC voltage is 2% higher, this is a complaint with your solar installer. Nevdi writes...
