The Sunny Tripower inverters has built-in electronic overcurrent protection on the DC side only when the unit is operating and the input voltage from the panels is greater than 188 volts.

Will this condition satisfy the requirements for over current protection and required by Art 690.9 in the NEC

    What does the manual say for AC wire gauge and breaker sizing?

    In general, the installation manual must tell you how to install per the NRTL Listing.

    you might as well elect the phones as they haven't made the politicians any smarter and they have access to all net material too. as far as i go with this.
