Hi @ijwhiting
ABB has had its problems, but appear to be sorting their stuff out. Sungrow is widely seen as the best Chinese inverter in the market, so that could be an option too.
Here’s an extract from our Best Solar Inverter article regarding ABB (now FIMER):
ABB decided to sell it’s entire solar inverter division to FIMER, a well established Italian based inverter manufacturer who took over ABB’s solar division in early 2020.
Background: ABB was a premium manufacturer offering a range of high quality string solar inverters, but gained a poor reputation from the old ‘Aurora’ branded inverters. ABB acquired Aurora ‘Power-one’ back in 2013 and thus had to deal with many warranty claims and service issues from the old generation Aurora inverters. Our specialists highlighted somewhat slow customer service compared to other manufacturers, even though ABB was a well respected industrial giant.
With the FIMER takeover and positive feedback on the new range of UNO-TL and UNO-TL-DM-PLUS inverters, it’s likely FIMER will maintain a strong market position going forward. It is hoped the new owner will also improve the previously slow customer support and service offered by ABB.
The UNO range of inverters have the common plug & play interfaces and wifi included on all models. To compete in the growing energy storage market, the second generation REACT 2 hybrid inverters from FIMER are a unique modular battery energy storage system (BESS) which can be either AC or DC coupled.
Cheers
