INV_PV_OVER_VOLTAGE on a GivEnergy Cloud portal / GivEnergy app and Wi-Fi dongle: PV over-voltage - check that the string voltage does not exceed 580 VDC
Short answer
On a GivEnergy inverter, INV_PV_OVER_VOLTAGE means: PV over-voltage - check that the string voltage does not exceed 580 VDC. The inverter stops until the fault clears or is reset. An engineer is needed to fix the cause.

What it means
The manual says: PV over-voltage - check that the string voltage does not exceed 580 VDC.
Part involved: PV input over-voltage.
Likely causes:
- PV over-voltage.
Is it safe?
Switch the inverter off at its isolator and call an engineer.
| Does the inverter stop? | Yes |
|---|---|
| Severity | Safety lockout |
| Engineer needed? | Yes |
The inverter stops until the fault clears or is reset.
Resetting itself: no.
Manual reset: yes, after string design is corrected.
What you can check
- Read and note the exact code and time from the inverter display or app (screenshot).
- Call the installer. Do not touch DC cabling.
- GivEnergy's customer guide allows a restart: turn off the DC (solar) and AC isolators, then restart the battery with its side button; or use the app/portal. Contact the installer if the alarm returns.
What the engineer will check
- Measure open-circuit string voltage (cold-weather Voc rise).
- Check string design against inverter max DC voltage.
- Check for mixed/incorrect module counts.
Who to ask for: PV installer / system designer.
Certification: Electrician competent in grid-connected PV (BS 7671 Section 712; IET Code of Practice for Grid-connected Solar PV), ideally the original MCS-certified PV installer; brand-approved/trained installer to keep manufacturer warranty.
