8.3.3. Disabled in the settings

The charger has been disabled in the settings.
Check the VictronConnect app battery settings page to ensure that the charger has been enabled.

8.3.4. Disabled by remote or BMS

The charger has been switched off via its VE.Direct port.
Note that in systems with lithium batteries together with an external BMS, it is typical for the solar charger to be switched on or
off as needed. This happens when the BMS turns off the charger due to full batteries or low temperatures (below ~5°C). Charging
automatically resumes when the batteries are discharged or have warmed up.
If the solar charger has unexpectedly been switched off, check the following:
VE.Direct RX port functionality check
The VE.Direct port can be used to switch the solar charger on or off by utilising its RX functionality in combination with, for
example, a VE.Direct non-inverting remote on/off
check if the RX port has been configured correctly. For more information, see the
Step 1
and the VE.direct protocol
Step 2 If a VE.Direct non-inverting remote on/off
If a non-Victron cable is used, check if it is configured correctly. For more information see the
Step 3
documentation.

8.3.5. Low lithium battery temperature

Charging may be suspended if the battery temperature is low, as a part of the battery protection mechanism, without necessarily
indicating a problem. The rationale behind this precaution is that lithium batteries are prone to damage when charged in
temperatures below °5C.
If this protection is triggered unnecessarily, please reach out to your installer to adjust the related settings.

8.4. Solar charger is externally controlled

Managed batteries or an inverter/charger with an external control system (e.g., ESS system) can govern the solar charger via a
GX device. The external system determines charging permissions and sets the charge voltage and currents.
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

• Reverse PV polarity. Refer to the
