- | To protect the battery from over-charging the panel input is shut down. To recover from this condition first disconnect the solar panels and disconnect the battery. Wait for 3 minutes reconnect the battery first and next the panels. If the error persists the charge controller is probably faulty. | + | 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. | ||

+ | SmartSolar models (not the BlueSolar models): upgrading to v1.4x firmware is a one-way trip, you cannot go back to an older firmware version once you upgrade to v1.4x. Reverting to older firmware gives error 116 (calibration data lost), this can be fixed by re-installing the v1.4x firmware. | ||
