I am trying to connect my Solar Panel (array of 2 x 265Wp 24v panels connected in series) to my Arduino UNO R3/Nano so that I can make a current/voltage measurement system that can be connected to the internet for remote data access.
I am not sure if an Allegro ACS712 30Amp chip could handle the voltage/current of my system which is usually over 60v dc and 4-5 amps. I can relate the ACS712 to a simple ammeter which is connected in series of the load where a shunt resistance is used between the two connecting ends of the ammeter.
The confusing part here for me is that the solar panel is connected via an MPPT charge controller to my 1.5 KVA inverter which in turn powers my house equipment, and I am not sure if the two connecting ends of the ACS712 can handle this load (which sometime exceeds to over 450 Wh) if connected in between the wire connecting the panel and charge controller.
Can anyone help me with a suggestion or better with a diagram showing the suggested system.
