Portable generator with PV

[Dale lee]

Hey guys, looking for some input here. I have not yet gotten to deal with anything as far as solar systems go. i recently had a customer request a portable generator inlet and then fell down a bit of a rabbit hole trying to figure out if this is even possible/ legal.

the system is Enphase, iq combiner 3 es, iq combiner 4, and no controller.

my concern is damaging the pv system or the generator itself and not really sure how to proceed.

What you don't want is for the generator to be connected to the PV system. One way to do that would be to connect the PV on the line side of the main panel and to install an ATS or interlock kit between the PV interconnection and the loads.

Portable Generator with solar

Probably a dumb question but not my area of expertise. Maybe I don't have any area of expertise LOL. Friend of mine was given a portable 9500 watt generator. They have a 100 amp panel with solar. Mostly gas appliances. What's the best way to y the generator in? Panel interlock? Does anything...
