I currently have an issues where if I turn off my inverter for my 5 hours of peak sun, I can charge my batteries to 100% (14+ VDC). As soon as I turn on my Renogy 2KW inverter, the batteries drop to close to 60% and holds steady, this is without any load on the inverter at all.
Any thoughts?
Panels:
4 100W 12V Renogy Mono panels
Charge Controller:
40A MPPT Renogy CC
Inverter: Renogy 2K Watts PSW
Batteries:
4 6V 230AH batteries in series and parallel for a 12V system @ 460AH
PS. I am about to install (2) 150W 12V panels in parallel with my current four panels in a parallel series. So, my total Amps per hour now is about 20A, with the new panels will be closer to 36Amps per hour.

The manual says it only uses 1.7A on idle so that much battery capacity shouldn't drop to 60% when only providing 1.7A. Can you tell us more about what is indicating the batteries at 60%?

No one knows how these folks determine % state of charge, certainly not while being discharged. The readings are bogus and should be ignored.
Best for me to use battery voltage as an 'indication' and experience how loads & time drop voltage
