<p>So to be clear, the inspector is wrong: it is NOT an NEC
requirement. It is only a California requirement. NEC 2023 only
requires a 100 A main load center and disconnect per 225.39(C).
Further, 710.15(A) allows the inverter and feeder to the Load
center to be even less in off grid applications. The rest of us
in the other 49 states are Not required to comply with the 200 A
requirement. </p>
<p><br>
</p>
<p>Good Luck out there. <br>
</p>

<p>Thank you,</p>
