Fimer

What Fimer does

FIMER, operating as MA Solar Italy Srl following its 2025 acquisition by MA Solar UK, is an Italian power-electronics manufacturer specializing in solar inverters, battery energy storage systems (BESS), and EV charging solutions. The company traces its origins to 1969 as Plessey Italy, was later held by MagneTek (1991), Power-One (2006), ABB (2013), and operated independently after FIMER acquired the ABB solar product group in March 2020. Following a 2023 restructuring under Greybull Capital and McLaren Applied, FIMER was acquired by MA Solar UK in 2025 and now operates from Vimercate and Terranuova Bracciolini in Italy, with additional manufacturing and R&D in India and sales offices in Singapore, Australia, the United States, and Japan.

The core product line centers on the PVS family of three-phase string inverters (10 kW to 120 kW, with up to six MPPTs) and the PVS980 central inverter for utility-scale projects, complemented by hybrid inverters (PVS-75/125, PowerUNO, PowerTRIO), the PowerX residential battery (up to 75 kWh), the PVX-215 distributed-storage battery, the FLEXA Home and FLEXA AC Station 2.0 EV chargers, and the MGS100 microgrid solution. Supporting software includes the Aurora Vision cloud monitoring platform, the Installer for Solar Inverters and MyFIMERCharger mobile apps, and O&M services delivered through five global repair centers. R&D runs across two international centers with more than 200 engineers, and the portfolio holds ISO 9001, ISO 14001, ISO 45001, and TUV factory inspection certifications.

FIMER generates revenue primarily through hardware sales of solar inverters, batteries, and EV chargers into residential, commercial and industrial (C&I), utility-scale, and microgrid segments across more than 100 countries. Pricing is quote-based and project-specific, delivered through a mix of regional contact centers, certified channel partners, and the Where to Buy online locator. Reference customers span automotive manufacturing (ZADI SpA, 860 kWp), aquaculture-solar hybrid projects (SunnyRich Group, 132 MW in Taiwan), distributed storage (AMP, 400 battery units), industrial-estate microgrids (Peel Business Park, Australia), and emerging-market distribution (S.L.A.M Power Solutions in Sri Lanka).

Direct peers

• Enphase Energy: Leading microinverter and module-level power electronics company with strong residential footprint in the US and Europe. Competes with FIMER's residential string/hybrid inverters (PowerUNO, PowerTRIO, PVM) for installer mindshare in distributed solar.
• Sungrow Power Supply: World's largest solar inverter manufacturer, offering string and central inverters across all power classes plus BESS and floating-PV solutions. Directly competes with FIMER in utility-scale tenders globally and sets the price benchmark FIMER must meet.
• KACO new energy: German manufacturer of string inverters (blueplanet series) for residential through utility-scale, plus BESS. Closely comparable to FIMER in European positioning, product line breadth, and target installer/utility customer base.
• GoodWe (Jiangsu GoodWe Power Supply Technology): Chinese inverter manufacturer offering residential, C&I, and utility-scale string inverters plus hybrid inverters and batteries. Competes with FIMER in cost-sensitive emerging markets and increasingly in Europe on price.
• Fronius International: Austrian manufacturer of string inverters (SnapINverter, Symo, Tauro) for residential, C&I, and ground-mount segments. Comparable Austrian/Germanic European positioning to FIMER with similar installer-channel business model and product overlap (e.g., Fronius Tauro vs FIMER PVS-100/120-TL).
• SMA Solar Technology: German inverter manufacturer with a directly comparable portfolio of residential, commercial, and utility-scale string and central inverters plus hybrid/BESS solutions. Both target European installers and utility-scale developers with overlapping product lines (e.g., SMA Tripower vs FIMER PVS series).
• SolarEdge Technologies: Power optimizer and inverter manufacturer with comparable residential and C&I portfolio plus DC-coupled storage. Competes directly with FIMER in European residential and C&I segments, where both sell through installer channels.
• Huawei Digital Power: FusionSolar division offering smart string inverters, smart PV optimizers, and integrated energy storage. Competes head-to-head with FIMER's PVS series in utility-scale and C&I segments globally, with strong digital energy platform differentiation.

Broad incumbents

• Delta Electronics: Large Taiwanese power electronics conglomerate with a solar inverter business alongside industrial automation, EV charging, and datacom. Overlaps with FIMER in string inverters and EV charging (both have AC charging portfolios) but operates across a much broader portfolio.
• ABB (Hitachi Energy solar inverter business): Former parent of FIMER's solar inverter operations before divesting to FIMER in 2020. Continues to operate in adjacent power conversion and grid integration markets with comparable products but is now a strategic peer rather than owner.
