Felicitysolar displayed its V-SKY and IVGM series hybrid inverter at RE+ 2025
The V-SKY series supports split-phase grid, while the IVGM series can handle single-phase, split-phase, and 3-phase supply
The company also introduced its lineup of lithium-iron-phosphate batteries from the FLA and FLS series
Felicitysolar, a provider of PV inverters and energy storage solutions, showcased its lineup of hybrid inverters and batteries at RE+ 2025, aimed at the US residential market.
The company displayed V-SKY and IVGM hybrid inverters. V-SKY supports a split-phase domestic grid supply and offers a power output (AC) range of 5 kW to 10 kW. In comparison, the latter, which is compatible with single-phase (220/230 V AC), split-phase (120/240 V AC), and 3-phase (208 V AC) domestic grid supply, delivers up to 8 kW of power (AC). Both inverters are compatible with AC-coupled configurations that combine PV arrays, battery storage, and a diesel generator (DG) on a single platform, thereby facilitating multi-source backup during grid outages or failures. Compared to the DC-coupled configuration, which connects both the PV arrays and battery banks on the DC side of the inverter, the AC-coupled inverter couples on the AC side, featuring a separate PV inverter and battery inverter on a single platform. In addition, V-SKY allows backup support beyond its storage capacity by activating the pass-through function that bypasses the entire system and feeds up to 100 A (AC) loads from the DG during grid outages. It can also operate in off-grid mode, independent of grid supply.
According to the company, these inverters address 2 major challenges for US homeowners – frequent extreme weather events and rising electricity prices – by providing emergency backup and leveraging the FSOLAR app’s Time-of-Use (TOU) settings, respectively.
The booth also featured 48 V lithium-iron-phosphate (LFP) batteries – FLA and FLS series. The FLA series with a stacked architecture and modular design offers flexibility in capacity expansion based on the homeowner’s backup needs. In comparison, the FLS series optimizes home storage capacity for a long lifecycle, but the company did not provide more details on the specifications.
The commercialization details of these showcased products are not publicly available at the time of publication of this article.
