I have an issue with SmartSolar 150/85 showing pv voltage equal(-0.5v difference) to battery bank voltage even when no pv input is connected.
As this is a new unit purchased for testing purposes, does anyone have an idea what might be causing this?
The unit can still charge correctly, but after removing input source, the pv voltage shows a higher voltage than battery bank until Remote jumper is removed. Needs to be reset otherwise it stays in Bulk mode even though no pv is connected.
It obviously has been damaged during testing, just not sure what to check for repairing.
Also finding it difficult to remove blue cover :)
Any help would be greatly appreciated.
