Hi All
I have a Easysolar, running Multiplus 48/5000/100 with 4x 390Wsolar panels ( 2 pane ls in series in parallel) and 4 x 48v Aeon batteries parallel.
I am getting low voltage faults late in the afternoon, batteries; are fully charged. The recorded voltage drops to 30 v resulting in Low battery Voltage. Fault and inverter shutting down.
I have checked connections to battery and all look ok.
what could be causing this wide range of voltage?
