Oh, I missed that. So it counts the Wh's up and down correctly? That is cool, for the price.

From what I have learned over the last few months, I would say that unit is missing the SOC display provided by a Coulometer like the one Steve recommended. Wattage and Whrs are certainly useful, but...

Ha, thank you! :flowers:

I installed it a bit differently, by hammering a piece of copper pipe flat, bending it, drilling it, and using it to attach the shunt to the point where a bunch of the...

Correct, two Trojan Grp31 100Ah AGM batteries (as described in the OP).

That's a good point! The SCC is a GoPower 30A PWM 30SQ controller, set to the AGM charging profile.

I'll let them run...

Certainly more elegant and sophisticated, yes.

It seems that over time, I am getting the hang of this based on the voltage.
For example, it is evening and I see 12.6V, I'm happy and have a drink....

I like simple, and looking at voltage is simple. 12V - battery almost empty ... 13V - battery almost full. Maybe I don't care about...

Steve, I have a similar situation with two Group 31 AGM batteries - can you describe how/where you installed the shunt? Perhaps have a picture? :bow:

Also, for our purposes, would a 100A or 350A...

After reading your post for a couple more times and thinking about it, this is how I imagine it works:

If the solar charge controller "thinks" the battery is full, it will drop down to ~13.5V and...

So, with the Sun getting a bit more intense, solar panel assisted voltages have been rising.

Recently, batteries are getting up to 14.5V. Is that harmful to the AGM batteries? This is without any...
