====== MPPT Solar Charger Error Codes ====== | ====== MPPT Solar Charger Error Codes ====== | ||
- | (draft) | ||
- | ==== Error Codes ==== | + | Solar Chargers indicate an error with their LEDs. See the [[https:// |
- | === Information 66 - Incompatible device === | + | Detailed error codes can be read with a remote panel, such as the Color Control GX or the MPPT Control. |
+ | |||
+ | ===== Error Codes ===== | ||
+ | |||
+ | ==== Err 2 - Battery voltage too high ==== | ||
+ | This error will auto-reset after the battery voltage has dropped. | ||
+ | This error can be due to other charging equipment connected to the battery or a fault in the charge controller. | ||
+ | This error can also occur if the battery voltage is set to a lower voltage than the actual battery voltage. | ||
+ | ==== Err 3, Err 4 - Remote temperature sensor failure ==== | ||
+ | Check if the T-sense connector is properly connected to a remote temperature sensor. | ||
+ | Most likely cause: the remote T-sense connector is connected to the BAT+ or BAT- terminal. | ||
+ | This error will auto-reset after proper connection. | ||
+ | |||
+ | ==== Err 5 - Remote temperature sensor failure (connection lost) ==== | ||
+ | Check if the T-sense connector is properly connected to a remote temperature sensor. | ||
+ | This error will not auto-reset. | ||
+ | |||
+ | ==== Err 6, Err 7 - Remote battery voltage sense failure ==== | ||
+ | Check if the V-sense connector is properly connected to the battery terminals. | ||
+ | Most likely cause: the remote V-sense connector is connected in reverse polarity to the BAT+ or BAT- terminals. | ||
+ | |||
+ | ==== Err 8 - Remote battery voltage sense failure (connection lost) ==== | ||
+ | Check if the V-sense connector is properly connected to the battery terminals. | ||
+ | |||
+ | ==== Err 17 - Controller overheated despite reduced output current ==== | ||
+ | This error will auto-reset after charger has cooled down. | ||
+ | Check the ambient temperature and check for obstructions near the heatsink. | ||
+ | |||
+ | ==== Err 18 - Controller over-current ==== | ||
+ | This error will auto-reset. | ||
+ | If the error does not auto-reset disconnect the charge controller from all power-sources, | ||
+ | A cause for this error can be switching on a very large load on the battery side. | ||
+ | |||
+ | ==== Err 20 - Maximum Bulk-time exceeded ==== | ||
+ | This error can only occur when the maximun bulk-time protection is active. | ||
+ | This error will not auto-reset. | ||
+ | This error is generated when the battery-absorption-voltage is not reached after 10 hours of charging. | ||
+ | |||
+ | This protection is default disabled in all Solar Chargers. | ||
+ | |||
+ | It is default enabled on the Skylla-i and the Skylla IP44. | ||
+ | |||
+ | Our advice is to not enable it on solar chargers. | ||
+ | |||
+ | ==== Err 21 - Current sensor issue ==== | ||
+ | |||
+ | This error will not auto-reset. | ||
+ | |||
+ | Disconnect all wires, and then reconnect all wires. Also, make sure the minus on the MPPT charge controller (PV minus/ | ||
+ | |||
+ | If the error remains, please contact the dealer, there might be a hardware defect. | ||
+ | ==== Err 26 - Terminal overheated ==== | ||
+ | Power terminals overheated, check wiring, including the wiring type and type of strands, and/or fasten bolts if possible. | ||
+ | |||
+ | This error will auto-reset. | ||
+ | |||
+ | ==== Err 28 - Power stage issue ==== | ||
+ | |||
+ | This error will not auto-reset. | ||
+ | |||
+ | Disconnect all wires, and then reconnect all wires. If the error persists the charge controller is probably faulty. | ||
+ | |||
+ | ==== Err 33 - PV over-voltage ==== | ||
+ | This error will auto-reset after PV-voltage has dropped to safe limit. | ||
+ | This error is an indication that the PV-array configuration with regard to open-circuit voltage is critical for this charger. Check configuration, | ||
+ | |||
+ | ==== Err 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, | ||
+ | |||
+ | ==== Err 38, Err 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, | ||
+ | * 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. | ||
+ | |||
+ | ==== Information 65 - Communication warning ==== | ||
+ | Communication with one of the paralleled controllers was lost. To clear the warning, switch the controller off and back on | ||
+ | |||
+ | ==== Information 66 - Incompatible device | ||
The controller is being paralleled to another controller that has different settings and/or a different charge algorithm. | The controller is being paralleled to another controller that has different settings and/or a different charge algorithm. | ||

- | === Error 114 - CPU temperature | + | When the charger needs to operate in stand-alone mode again, not controlled by a BMS, it needs to be reset: |
+ | |||
+ | * VE.Can solar chargers, go into the setup menu, and change setting ‘BMS’ from ‘Y’ to ‘N’ (setup item 31). | ||
+ | * VE.Direct solar chargers, reset the charger to factory defaults with VictronConnect, | ||
+ | |||
+ | Note that (solar-)chargers automatically configure themselves to be BMS-controlled when they are connected to one; either direct or via a Color Control GX or Venus GX. | ||
