bonjour

surement un probleme de réglage entre votre mppt et un autre système de charge:

Err 29 - Over-Charge protection

This error will auto-reset once the battery voltage drops below the float voltage. To protect the battery from over-charging the battery is disconnected.

Possible causes:

  • over-sized PV array configuration, if there are too many panels in series the battery voltage cannot be reduced any further. Consider wiring more PV panels in parallel to reduce the voltage.

  • configuration issue, check if the battery settings match with the installation (especially absorption and float voltage settings).

  • another charger in the system raises the battery voltage above the expected level.
