Finn's Fimer Inverters Review & Verdict
Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO
FIMER acquired ABB's solar inverter business in 2020. After struggling for a few years, the company went into administration and was acquired by another firm in late 2024. So, while producing good quality gear, I can't recommend their inverters given the previous instability and while the dust is still settling post-acquisition. I'm taking a wait-and-see approach.

Company Info
FIMER began producing inverters originally for large-scale renewable energy projects. It wasn't until 2020 the firm entered the home and small commercial market with its acquisition of ABB's solar inverter business.
The ABB acquisition, announced in July 2019, was completed in March 2020 - giving FIMER a presence in 26 countries including Australia. A change in branding on the inverters didn't begin to occur until mid-2021 - so, up until that point they were still being produced with the ABB name.
With the acquisition, FIMER said it became the fourth largest solar inverter supplier in the world at that time and had had three solar inverter manufacturing facilities - two located in Italy and one in India. It also had several R&D facilities, one of which was in Finland.
FIMER had a good reputation and was expected to carry on the tradition of excellence set by ABB.
But the last couple of years haven't treated the company too kindly. Like many other solar manufacturers, it was impacted by lockdowns and shortages of some components and raw materials. Along with some management related challenges, the firm ran into cash liquidity issues and production activities slowed. However, it developed a "relaunch plan" in 2022 designed to get it back on track. That obviously didn't work because the company subsequently went into administration and the administrators launched proceedings for its sale in July 2024.
In late November 2024, the company announced FIMER had been acquired by a subsidiary of McLaren Applied Group,
FIMER Inverters In Australia
FIMER's main product line in Australia is the UNO-DM inverter. But given FIMER's current situation, you might want to check out specifications and estimated pricing of other offerings on SQ's solar inverter comparison table.
FIMER Solar Inverter Warranty Notes
FIMER committed to honouring all existing ABB warranties.
Under the new FIMER branding, there was a ten year full replacement warranty on the UNO-DM range single phase solar inverters and five years on three-phase FIMER string inverters; which could be extended to 10 years for an additional sum.
If you're having problems with your FIMER solar inverter, your first port of call for resolving the issue is the company that installed the unit as that business has the responsibility of dealing with warranty issues. However, in the event the original installer isn't around any more for whatever reason, FIMER says you should submit an enquiry here; or you can contact the firm on 1800 769 663.

We have just had our system upgraded from the initial Power-One Aurora PVI-3.0 OUTD connected to 9 x 218 watt panels, to adding an additional 5 x 206 watt panels, totalling 2992 watts of total panel power across two panel strings (even though I know the calculation is NOT that simple) and let me just say... the Inverter has never performed better!
Our new daily peak wattage in the Inverter statistics is over 3150 Watts! That's Hyundai positive tolerance solar panels for you! And the most we've generated per day since the upgrade is 17.5KWh! That's $8.75 of real money in the bank (after buying back what we use).
I've never been happier. The electricity company owes ME money!!!
