I'm playing around in creating a battery monitor for a portable power pack (to run a small invertor) and I may want to charge it with a charger or solar panel, The idea is to monitor charge going in and current out of the battery so I can roughly display runtime and AH left or how many AH has been put back into the battery. I know there are high side current monitors out there but recently I've done a similar thing to measure current draw using one sensor, This can measure the current flowing in and out the battery but the trouble I'm facing is that if I have a solar panel connected at the same time and running the small invertor I can't measure both at the same time. Because I've got a couple of these built already my idea was because I've got two of them built use one for the charging side and one for the current draw side, But not sure means everything is in the low side with common ground if there would be any effects or issues. I did not just want to try it incase I destroyed the micro or ADC converter or anything like that,
I've attached a drawing to show how I think it could be connected any feed would back or suggestions would be great
