I have zero experience with Growatt string inverters, only off-grid, and have only dealt with dissatisfied customers. Each inverter requires a separate transformer if you want split phase 240v. They also seem a bit wimpy on big loads. But then again - my opinion is worth every penny you have paid for it. ________________________________ From: RE-wrenches <[email protected]> on behalf of Drake Chamberlin via RE-wrenches <[email protected]> Sent: Friday, September 1, 2023 9:55 AM To: RE-wrenches <[email protected]> Cc: [email protected] <[email protected]> Subject: Re: [RE-wrenches] Fronius USA available 2023 & 2024 ?
My suppliers don't have any Fronius now. I try to buy entire systems, if possible. What is now available for a string inverter is the Grow Watt. Can anyone either recommend them, or warn us not to use them.

Fronius has a strong presence in Canada with good tech support. We also have a very low failure rate - can't remember the last time we replaced one. There were some supply issues earlier this year but we are receiving inverters and parts. They also have a good rep for low failure and good service in Australia and Europe. Not sure why the US gets short shrift.

The reason I know is they stopped sending me AFCI repairs about 2 years ago. There was not any support from their installers in remote places like the Sierra range. I would second Tump on picking a good company with real money and products. Below is a new one this fall. https://shop.se.com/us/en/schneiderhome Dave Angelini Offgrid Solar "we go where powerlines don't" https://offgridsolar1.com/ e-mail [email protected]<mailto:[email protected]> text 209 813 0060 On 2023-08-25 3:55 am, Tump via RE-wrenches wrote: Mick, I would avoid trying to use a manufacture that has little NO support OR product availability. IF your using the Schnieder Pros, I would suggest you consider the 600/100 CC. This product is more then capable of handling 7kW of input. They are available, compatible w/ their (Schnieder's) battery monitoring AND offer a system that is able to "talk" to itself. Off grid should be uniform in design so clients/caretakers and you, have little adding to confusion IF/when their is an issue. Lord knows Im not saying there won't be an issue w/ Schnieder's product, but we DO have a product, tech support & other persons w/in the company we are able to call on. AC coupling, for off grid while we have Hi V CCs available is for me a thing of the past.

(6kW AC output, single phase 240 volt 60 hz) This p/n is in the Greentech portal but my particular branch hasn't done much with Fronius. Today the branch manager told me "Fronius no longer exists." Can any of you confirm or correct this report? I have an off-grid opportunity for which I wish to AC couple some of the PV. If Fronius USA has indeed "left the building", are there other string inverters that can be selected for country code "off grid 60 hz"? I'd like for the PV inverters to only curtail their output wattage if there's a frequency shift from the grid forming inverter (frequency/watt). Schneider XW Pro units would be forming the grid. Schneider has a white paper # 990-6421 on AC coupling but this document is almost three years old & no help at all in finding compatible PV inverters. Rapid shutdown is not mandated for this gig & each array would be evenly illuminated. IIRC, the List hasn't been highly enamored with SolarEdge in recent years; is that still the consensus?
