Kevin,
Kevin,
Here is what I use.
A 100 Amp shunt with big wire connections to go in series with the battery
leads, and small set of screw terminals to connect to the sensing circuit. The
one below generates 100 MV of voltage at 100 amps of battery charge.

Kevin, are you using a charge controller between the solar panel, rpt,
and batteries?
Does your controller provide any kind of monitoring of current or
voltage or state of charge?
The op-amp circuits can also be extended in range beyond the VCC by
using a voltage divider on each side of the input

The classic textbook method would be to put a current shunt in series with
your DC source and measure the voltage drop across it. A current shunt is
just a precis
