For those reading charge controller with Raspberry Pi, what about battery monitor?
In the system with Renogy components I bought with my sprinter van, I noticed that the 12v DC loads are all coming off the Rover 60a charge controller, and the inverter is wired directly to the batteries. According to the manual this is how it's supposed to be done. I am using a Raspberry Pi to read the data from the rover charge controller where I can get a lot of metrics, but the true load being pulled (DC + AC) is not possible. Are any of you doing additional monitoring via something DIY or off the shelf that could also give the raspberry pi access to the battery information, including the total load draw?
