Good question. If not, I'm planning to throw a soft start module into the mix. https://www.microair.net/products/easystart-364-3-ton-single-phase-soft-starter-for-air-conditionersWill the inverter start the AC unit? AC units need a large starting current for the compressor and some inverters balk at that.
I'm curious if it would be better to get 9 panels and go 3S3P. Maybe I need more headroom than 150 OCV with the Growatt?
