Search for it in the forum, it's a popular topic.
A MIN11400TL-XH-US is a bit undersized for your number of panels but it's a good starting point for discussion. It is $1500 and should be legal to use with PG&E. There's at least one fan of this inverter for this use case, on this forum.
UL1741SA = recent (~5 years) revision to the UL standard for inverter, that (for the purposes of this discussion) added various ways to throttle back output from grid tie inverters.
AC coupling grid form = Normally grid tie inverters will only turn on if they see the grid. Powerwalls (like couple other similar equipment) are capable of creating a fake grid that can convince grid tie inverters to turn on. And then they use the 1741SA control functions for power balancing.
Fortunately you either intentionally or accidentally picked a number of panels that the powerwalls can manage, they have a limit.
yeah, i was just talking to the installer of the batteries. and he said my array is too big
"The power wall 2 is limited to 5 kW of PV input, so for you, with two powerwall 2's, your maximum PV input is 10 kW. That PV system that you described won't always be producing at maximum, but during an outage at noon in the summer, your system will shut down the PV...and might injure your batteries."
would you worry about that? it seems a perfect storm (full perfect sun, power outage mid day, house not taking any draw from panels) would have to happen to have a concern? inverters can't throttle back the output?
Also, which way is that growatt undersized? the max output of 48amp seems on the low side, otherwise it can easily handle the PV array.
it turns out the panels are 408watt + up to 150w bifacial gain which is obviously unlikely.
I haven't installed the panels, so i could always just throw a couple in storage for when/if one dies in the future.
i was told i do need a hybrid inverter, which that growatt isn't. do i not need a hybrid because the powerwalls are ac and not dc?
