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
If you have any other questions, let me know
