Parallel inverters ac breaker size

Hi. I believe when you Parallel 2 sunsynk inverters you should only use one breaker for ac in and one for load? Is this safe? I.e one 40-45A breaker to protect load side?

I have a 14,440kW array, the 3.6 inverters are able to output at up to 3.6kW * 2 and charge batteries with the residual output, I have 30kW storage and building, I am able to utilise the battery power in the evening to supplement our caravan park usage (it peaks about 19.00 - 22:00 @ 20kW) with a constant draw of 5kW through out the night, I then recharge the following day and so the cycle continues
