question

@MasterCATZ

They are not officially supported.

That being said there are people that do use them. There are few posts on the forum about what people are doing. Enphase have a paper on them.

I have not used them personally.

Do they respond to frequency shift? Of they do then you can use them. There is also the possibility to have them on the AC out2 and program it to shut off if the batteries are full (so use the generator assistant in the inverter) and maybe use them that way to be safe. But have some DC PV as well.

By the inverter blow up ... they probably mean that there is no way for the inverter to officially control them so possibly you will have over charged batteries, AC voltage rise and unexpected shutdowns. All of which are not good scenarios being off-grid.

ok thank you for the answer

I guess I will need to buy a envoy so I have the software for controlling the micro inverters so they shutdown when freq changes

I thought it would only charge batteries if it was from the AC input side

but turning off AC2 could work as well, was also wanting to run a A/C so that might scrap that idea when batteries are full

its just soo much cheaper using grid tied AC inverters (mostly free from everyone upgrading )

than it is to keep buying more DC Chargers

ac coupled chargers can be used fine as long as they support frequency shifting,

enphase work but they can give you headache's to get working properly... follow alexandra's enphase link is the best option

DC is always the better choice if you can
