SolarEdge Technologies unveiled its next-generation three-phase solar inverter and dedicated home battery for the European residential market at Intersolar 2024, the company announced on 19 June 2024. The company said the products are expected to be available in the second half of 20251.
The inverter is designed to reach a higher power class of up to 20kW and is intended for full home backup applications, according to the announcement. SolarEdge said the incorporation of the latest advancements in 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 market. 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 said will allow flexibility and scalability in both power and capacity. The modular design is devised to optimise the performance of each unit independently, with automatic balancing of new and old modules. Built to support the SolarEdge Home Backup Interface, the system will be able to provide extended multi-day home backup, and together with the SolarEdge ONE energy optimisation system it is designed to optimise Time of Use (ToU) or dynamic energy tariffs1.
For installers, SolarEdge said 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."
The announcement gives no UK-specific pricing, no confirmed UK launch date and no efficiency figures in numbers. Those details have not been reported1.
Why it matters for households
The direction of travel here is towards larger home systems. A 20kW inverter class sits well above the typical domestic installation, and the pairing of a bigger inverter with a stackable battery points to homes running more of their load, including backup circuits, from stored solar. For a household weighing up hybrid inverters that combine solar and battery in one unit, this is a further option in that category, though not one that can be bought yet.
The claims that carry practical weight for energy independence are the ones about backup and tariffs. Multi-day backup, if delivered, changes the calculation for homes that want to keep running through grid outages rather than simply cut bills. Optimisation of Time of Use or dynamic tariffs matters for households on time-varying import prices, where shifting battery discharge to expensive periods is the main source of savings. Automatic balancing of new and old battery modules is relevant to anyone who expects to add capacity later rather than sizing the battery once.
None of this is available to buy, and no UK specification, price or date has been given. Households considering adding battery storage to a solar system now are choosing from products already on the market, not from this one.
What happens next
SolarEdge said the NextGen 3PH Solution is expected to be available in the second half of 20251. The company made the announcement at Intersolar 2024, where the product debuted at its booth in Hall B4, Stand 1101. No further dates have been reported.
