For PV, a clamp ammeter with DC (not just AC) amps scale is very handy.
I just bought one from Harbor Freight for $100, but I think people have found $30 models.
What I was looking for was 0.01A resolution so when reading a PV string that produces about 1A due to low sun angle, I'll have 1% resolution and 5% accuracy.
Also 600A or higher for my battery.
The meter I got has 1000A, 600.0A, 60.00A scales.
