I have an existing Pylontech installation that suddenly started pushing voltages too high.
The only change was ESS set from "Keep batts charged" to "Optimized with battlife"
By returning it to "Keep batts charged" does not help
The errors then started. It seems to be the MPPT not following the set voltages.
All settings were confirmed with this guide: https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom
- Venus GX
- Quattro 48/8000/110-2x100 rev2
- SmartSolar Charger MPPT 250/100 rev2
- 2x Pylontech US3000B
- 3x Pylontech US3000C
- All firmwares updated to latest when errors started - did not help.
Venus GX settings
(Charge voltage was set here to 52V only as a test, it did not help)
Any assistance ill greatly be appreciated!
