ShuntMon 500A or 1000A

How should ShuntMon size be determined, 500A or 1000A?

Hi JPPower,

Consider the rated output of your inverter or MPPT charger, divide by the lowest battery voltage you expect, add a bit for inefficiencies and overheads. If you find it’s above 400A, then go for the 1000A model, otherwise, go the 500A :slight_smile:

If you have any other questions, let me know :slight_smile:
