Victron recently released firmware update v1.37 for their SmartSolar Chargers. This fix is especially important for all 150V and 250V SmartSolar Charger models. The BlueSolar Charger range is not affected. The new v1.37 firmware fixes a problem that can, in certain cases, cause the device to fail.

If you notice that your Solar Charger is no longer charging the batteries; or, in the case of larger models, it is behaving erratically – then the hardware has already failed and the unit will need to be replaced, as by that stage it will be too late to apply the firmware fix.  This update will prevent the failure from occurring.

How to apply the firmware update

Standalone Solar Chargers can be updated with VictronConnect; the recently released version 5.1 will automatically update all solar chargers to v1.37. Documentation for that is available here.   For systems on the VRM Portal; you can use the new remote firmware update feature as described in the video below:
