January 23, 20215 yr Hi, I just want to find out if I am on the right track by connecting my Raspberry Pi with icc software and a BVM 702 meter to measure soc on my battery bank. Is the B1 and B2 wire correct for midpoint measurement
January 23, 20215 yr Author Here is a sketch with the BVM connections, is this correct for midpoint. thank you

No, the above will only measure current to/from the right hand inverter from/to the battery. You want the shunt to be before both of the inverters (at the left end of the above diagram). Quote Is the B1 and B2 wire correct for midpoint measurement ? I see no B1 or B2 above, and the battery isn't on the diagram, let along the midpoint of the battery. Sorry if I'm missing something obvious.

Sorry if I'm missing something obvious. Thanx Coulomb, I placed the sketch with the BMV on the second post, it didn’t want load on the first question, files to large. But I really appreciate your advice and knowledge
