Hello Hedges (and everyone), I have been considering the purchase of 4 Sunny Island inverters through eBay. I currently own two Victron inverters and I am pretty comfortable with them and they seem to be working well. The reason I'm considering the purchase of the Sunny Island inverters is because I need more power than the two 3kva inverters I currently have. I could go with a much bigger Victron, but eventually this inverter setup will be in shop building, which is currently off grid but might in the future have a grid connection (I'd like the option either way). Victron does not currently have much to offer in the US from a code compliance perspective. My current inverters probably do not have all of the associated US certifications, and so therefore they are setup in a mobile fashion, similar to using a generator to power a building. I'd like to permanently install the future inverters and pass code compliance certifications (I didn't find anything that seems to indicated that the Sunny Island couldn't pass code compliance in the USA).
I've read posts about AC coupling with Sunny Island and having some issues with inverter models from SMA, but it appears you were able to work through these problems.
Hedges (or anyone with experience) based on experience, would you do it all again and repurchase your Sunny Island inverters, or would you look elsewhere?
I'm really spoiled by the Victron central control, the Cerbo GX device, etc. The Sunny Island website isn't as user friendly as the Victron site in my opinion, and I'm having some difficulty figuring out if I can bridge an older inverter model like the Sunny Island into the SMA tech stack that connects to the internet. Do you know if it is possible to make the Sunny Island connect to the SMA Data Manager M by using an SMA Communication Gateway? https://www.sma.de/en/products/monitoring-control/sma-com-gateway.html
Thanks for your time.
