I want to install a DC breaker (200 Amps) between my 450Amphr 24 volts battery bank and my 3000W inverter. The type of breaker I have available is the MCB type. I don't know which of the terminals of the breaker should be for the battery and which should be for the inverter. Should the upper (input) part of the breaker be connected to the battery and the lower to inverter or vice versa?
