Batteries Are Not Charged; Battery Is Full - Victron energy SmartSolar MPPT 150/60 Manual

When external control is active, it is visible on both the VictronConnect app and the GX device. This is normal behaviour and is
not a fault.
The VictronConnect app indicates that the charger is externally controlled.

8.5. Batteries are not charged

This chapter explains scenarios where the charger is active, but the batteries are not charging. In such cases, the VictronConnect
app will show the charger as active with the correct charge voltage, but the charge current will be at zero or very close to zero.
There are several reasons why this can happen, namely:
• The battery is fully charged, and no further current is required. This is normal behaviour and is not a fault. Refer to the
is full [49] chapter for more details.
• Reverse PV polarity. Refer to the
• PV voltage is too high. Refer to the
• Reverse battery polarity. Refer to the
• The solar charger is disconnected from the battery, possibly due to cable, fuse, or circuit breaker issues. Refer to the
not connected [50] subchapter for more details.
• Incorrect charger configuration, e.g., low charge voltage or current setting. Refer to the
subchapter for more details.
• The charger is externally controlled (ESS or DVCC), which is normal and not a fault. Refer to the
controlled chapter for more details.
• The temperature-compensated charging feature is active, and the battery temperature is too high, or the feature is
misconfigured. Refer to the Wrong temperature compensation setting

8.5.1. Battery is full

Once the battery is full, the solar charger will stop or significantly reduce its charge current. This is especially evident when DC
loads are not drawing power from the battery. It is important to note that this behaviour is normal and not a fault.
