This week we received a INA210 from Texas Instruments. Officially it’s a “Voltage Output, High/Low-Side Measurement, Bi-Directional Zero-Drift Series Current Shunt Monitor”. It allows us to monitor the amps flowing through the shunt, and to display the “right now” amp

Since we are involved in off grid solar power systems, we have a need to monitor battery voltage. The Arduino can do this easily with a simple voltage divider. With some simple mods, we can control loads, generators, or notifications
