Once the settings menu is closed on the display, charging will resume.
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 remote on/off terminal or 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:
Remote terminal check
Typically, both the remote connector and the wire loop must be present for the solar charger to function correctly. In more
advanced systems, the remote on/off terminal might be connected to an external device, such as a switch, relay, or battery
BMS system for external control.
Step 1
Verify that the connector block with the wire loop is present.
Step 2
Verify that the connector block has been inserted all the way in.
Verify that the wire loop is making electrical contact with the connector
Step 3
block.
Take note of the various methods the solar charger can be activated via the remote terminal:
• ON when the L and H terminals are interconnected via a switch or a relay contact.
Step 4
• ON when the L terminal is pulled to battery minus (VL< 3.5V).
• ON when the H terminal is high (2.9V<VH<Vbat).
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.
