You can connect up to 4 x sensor modules to it. Each sensor module measures RMS voltage, RMS Current and True power (4000 times a sec) with a max current capability of +200amps and – 200 amps. The battery monitor logs this information and can draw graphs on screen (true power, Peak’s encountered throughout the day, max, min and avg). The battery monitor uses this information to determine battery sate of charge and estimate time left on battery. It can monitor the health of the battery and indicate solar production, usage efficiency, and appropriate use of available power and battery. It can indicate the shortfall of power (if any) and the times (+ values) that the battery reaches max / min voltage and max / min SOC (state of charge), can indicate the time (+ values) of peak load and peak charge.

With 1 sensor it can give all the information but can only do this based on the net totals (differences) of power coming in and power going out.

With 2 sensors the power in and out can be plotted and analyzed independently, better understanding of load behavior and better understanding of the effects of whether patterns and shading on PV production.

If more charging sources like a wind turbine is added then it can be connected to a new sensor or it can be connected in with the charging (solar power in) sensor.

If you want to monitor 3 loads independently then you can add 2 more sensors otherwise al the load will be monitored with one sensor
