i added extra batteries to yesterday, previous ones install Jan 2019. Everything was off and isolated. when i restarted my one regulator was not producing on the one string. it was 6 pm so i left it to check today when the son comes up.
at around 7 pm i got a error 38. Its not resetting, anyone any ideas ?
Ok.. I got the repeated error alert again today. As copied from the
post above..
There is another device connected to the battery, which is configured to a higher voltage. For example a MultiPlus, configured to equalise at 17 Volts, while in the MPPT this is not configured.
Well.. Yes there is.. 2 Victron controllers and a CERBO all networked. So neither controller is configured differently. 99% of today the controller and array are working like they should..
Hi Martin,
regarding Errror 38:
To protect the battery from over-charging the panel input is shorted.
Possible reasons for this error to occur:
The Battery voltage (12/24/48V) is set, or auto-detected, incorrectly. Use VictronConnect to disable auto-detect and set the Battery Voltage to a fixed voltage.
There is another device connected to the battery, which is configured to a higher voltage. For example a MultiPlus, configured to equalise at 17 Volts, while in the MPPT this is not configured.
The battery is disconnected using a manual switch. Ideally the charger should be switched off before disconnecting the battery, this avoids a voltage overshoot on the charger output. If necessary the voltage trip-level for the PV Short protection can be increased by raising the Equalization voltage set-point (note: equalization does not have to be enabled in this case).
The battery is disconnected using a Lithium charge relay connected to the “allow-to-charge” output of a BMS. Consider wiring this signal to the Remote terminal of the charger instead. This shuts down the charger gracefully without creating a voltage overshoot.
Error recovery:
Error 38: First disconnect the solar panels and disconnect the battery. Wait for 3 minutes, then reconnect the battery first and next the panels.
Error 39: The charger will automatically resume operation once the battery voltage drops below the float level for 1 minute.
If the error persists the charge controller is probably faulty.
