I'm just curious, if the inverter label says Maximum Continuous Output (AC) 7.6 kW: 32A | 3.8 kW: 16A and the solar roof breaker is 40A, does it mean I have a 7.6 kW inverter or it means nothing?
Max continuous output in amps multiplied by 240 volts gives you your inverter size (power) in kW. So 32*240 = 7.68kW.
You need a 40 amp breaker as you can only feed an 80% continuous load through a circuit (40 * 80% is 32). Same reason you need a 60 amp breaker for a 48 amp continuous draw from a Tesla Wall Connector.
