Monitoring accurate status of lead batteries in photovoltaic systems?
Hello, I am looking for a solution to solve this challenge since current systems typically measure voltage which in the long run is not accurate for measuring the status of lead batteries in photovoltaic systems. Could you help?

Several company's make battery "Gauges" which use a restive shunt to measure amps In and Out of a battery, and count the remaining capacity from it's monitoring. They are only a little better than a simple volt meter. And if you let a battery sit idle for 4 or 6 hours, you can get a accurate state of charge reading with a volt meter.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
