That will do the job very nicely
My dream meter would show charging amps
Volts
And count down amps used in a minus count
Every night when charging was done, example four batteries charging at 3 amps total at 14.2v, I would push one button
Count would goto zero
In the morning it would show me the amp hrs used overnight
-40 -60 etc..
Show me how many I am down , used overnight
I am using the same one (well the 200 amp shunt version)
And in the morning I look at the meter then mentally deduct the amp Hr S left from the set value example 300 left in bank from the 400 set value 100 used
But it will take 115 amp hrs charging to replace the 100 use (old batteries) and the meter will stop counting when 100 goes back in and reached the 400 set point, I look at the meter amps and the charge light and see 18 amps charging and know the batteries are not topped off,
I keep charging
When the amps get to 10 amps charge I shut off the generator and let the solar carry on
The less amp hrs used and the Less recharging needed the easier your routine will be
