SolarEdge Technologies unveiled a next-generation three-phase solar inverter and a dedicated home battery for the European residential market at Intersolar 2024, and said the products were expected to be available in the second half of 20251. The announcement was made on 19 June 20241.
The inverter is designed to reach a higher power class of up to 20kW and is intended for full home backup applications1. SolarEdge said the use of Silicon Carbide (SiC) switches is expected to significantly decrease the size and weight of the new inverter per kW while boosting efficiencies and power density, to achieve what it describes as the highest efficiency in its category currently on the market1. The inverter is also designed to support the SolarEdge Home wireless network1.
The dedicated battery platform uses a new compact and stackable architecture, which SolarEdge says will allow flexibility and scalability in both power and capacity1. The modular design is devised to optimise the performance of each unit independently, with automatic balancing of new and old modules1. Built to support the SolarEdge Home Backup Interface, the system is designed to provide extended multi-day home backup, and together with the SolarEdge ONE energy optimisation system is designed to optimise Time of Use (ToU) or dynamic energy tariffs1.
For installers, SolarEdge says the offering is designed to significantly simplify and shorten installations, servicing and commissioning processes, while offering one of the smallest footprints in the industry1.
"Our next generation residential offering will be optimized to meet the trend in European markets for larger PV and storage systems. Coupled with our advanced energy management software capabilities we believe we are strongly positioned to offer a differentiated solution in this segment."
SolarEdge describes itself as addressing a broad range of energy market segments through its PV, storage, EV charging, batteries and grid services solutions1. The company's existing SolarEdge inverters and power optimisers range is covered separately, as are hybrid inverters that combine solar and battery functions in one unit and the wider question of adding battery storage to a solar system.
Why it matters for households
The announcement points to equipment aimed at larger homes with bigger rooftop arrays, where a 20kW power class and multi-day backup capability go beyond the typical single-phase residential setup1. For a household weighing up energy independence, the relevant claims are the ones about self-consumption, backup duration and tariff optimisation: a system that can store more energy and manage when it is drawn can reduce reliance on the grid at peak times and during outages1. The modular battery design, with automatic balancing of new and old modules, is presented as a way to add capacity over time rather than replacing a whole battery1. No UK pricing, certification or confirmed launch date for the UK market has been reported1.
What happens next
SolarEdge said the products were expected to be available in the second half of 20251. No further dated milestones have been reported1.
