If the error persists the charge controller is probably faulty. | + | To protect the battery from over-charging the panel input is shorted. |
- | === Information 65 - Communication warning === | + | 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. | ||
