Error 34 - Pv Over-Current; Error 35 - Pv Over-Power; Error 38, Error 39 - Pv Input Shutdown; Error 40 - Pv Input Failed To Shutdown - Victron energy SmartSolar MPPT RS 450 100 Manual

7.4.17. Error 34 - PV over-current

The current from the solar-panel array has exceeded 75A. This error could be generated due to an internal system fault.
Disconnect the charger from all power-sources, wait 3 minutes, and power-up again. If the error persists the controller is probably
faulty, contact your dealer.

7.4.18. Error 35 - PV over-power

This indicates that the panel voltage is too high in combination with the desired battery voltage.Reduce the PV voltage by
removing panels from the string, or rewiring them in parallel.

7.4.19. Error 38, Error 39 - PV Input shutdown

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 its maximum voltage setting
(normally Equalisation or Absorption voltages), for 250V versions or float voltage for the other units. It can also takes a minute
to reset the fault.
If the error persists the charge controller is probably faulty.

7.4.20. Error 40 - PV Input failed to shutdown

If the charger is unable to turn off the PV input, it will go into a safe mode in order to protect the battery from over-charging or
having a high voltage on the battery terminals. In order to do that, the charger will stop charging and disconnect its own output.
The charger will become faulty.

7.4.21. Error 41 - Inverter shutdown (PV isolation)

PV panel isolation resistance too low. Check the PV array cabling and panel isolation, the inverter restarts automatically once the
issue is resolved.

7.4.22. Error 42 - Inverter shutdown (Ground Fault)

The ground leakage current exceeds the allowed 30mA limit. Check the PV array cabling and panel isolation. This error will not
auto-reset. Check the installation and restart the unit using the power-switch.

7.4.23. Error 43 - Inverter shutdown (Ground Fault)

The voltage difference between Neutral and Ground is too high.
Inverter or Multi (not connected to the grid):
• The internal ground relay is activated but the voltage over the relay is too high. The relay might be damaged.
Multi (connected to the grid):
• The ground wire in the installation is not present or not connected properly.
• Line and Neutral are swapped in the installation.
This error will not auto-reset. Check the installation and restart the unit using the power-switch.
