FIMER showcased its PVM-75/125-TL string inverter with a rated power output range of 75, 100, 110, and 125 kW at the show
The company also showcased its cabinet-based PVX-241 C&I ESS, featuring a 140 kW PCS and a 241 kWh storage section
Together, these products can convert an existing PV capacity to an AC-coupled PV-plus-storage system
Italy-based PV inverter and energy storage system (ESS) maker FIMER showcased its latest commercial & industrial (C&I), utility, and residential product lineup at Solar & Storage Live UK 2026.
The company displayed the PVM-75/125-TL string inverter and PVX-241 ESS for C&I consumers. The inverter features up to 12 built-in MPPTs, each rated at 32 A, and supports a maximum PV capacity range of 76.5 to 127.5 kW. It then inverts the DC power to AC in four maximum full-load (3-phase) categories: 75, 100, 110, and 125 kW. It has a maximum conversion efficiency of 98.8% and operates at temperatures between -25°C and +60°C, with derating starting at 30°C.
Measuring 965 × 380 × 715 mm (W × D × H), the inverter also supports pairing with an existing string combiner box for a revamping project. It can be installed horizontally or vertically relative to the ground or roof level. For safety, this inverter includes DC and AC surge protection devices on its DC and AC sides, respectively, which protect the inverter from transient overvoltage in the event of lightning. The inverter also provides protection against DC reverse polarity and arc-fault current.
In comparison, PVX-241 combines a storage section and a bidirectional converter or power conversion system (PCS) (instead of a standalone inverter) in a 1,150 × 1,800 × 2,100 mm cabinet. The storage section places four vertically stacked battery packs, each rated at 60.25 kWh and 314 Ah, for a total storage capacity of 241 kWh. This capacity corresponds to a full-load charging/discharging power (DC) of 107.52 kW. It features a liquid-cooling-based thermal regulation mechanism. The built-in PCS inverts the discharge power to up to 140.4 kW (3-phase, 415 V) at 150.3 A and vice versa when charging from the grid. The product datasheet specifies a lower maximum conversion efficiency of 91.3% at system level (PCS + battery) relative to the string inverter.
This ESS can be paired with an existing PV array via the PVM-75/125-TL inverter through a common main distribution panel. This configuration creates an AC-coupled PV-plus storage system with the grid.
In addition, FIMER showcased its 300 kW PVS-330-TL string inverter, 2 MVA PVS-990 central inverter, and 2.5 MVA PVS980 bidirectional converter for the utility applications.
For residential applications, the company featured its FIMER Power Platform, including PowerUNO, PowerTRIO, and PowerX.
