What I noticed
DC circuit breakers are not the same as AC MCBs — never use AC breakers on DC circuits. You need one per string on the DC side of the inverter. For a single-string system (up to about 5kWp on a 20A breaker), one pair covers you. Check your inverter datasheet for the maximum overcurrent protection device rating for each MPPT input.
