Solis, the inverter brand of Ginlong (Solis) Technologies, announced on 7 November 2024 a new low-voltage three-phase hybrid inverter, the S6-EH3P(8-15)K02-NV-YD-L. The company describes it as "a low-voltage, three-phase hybrid inverter designed for residential and small commercial applications"1.
The model name indicates an output range spanning 8 to 15kW. Solis quotes a battery charge efficiency from solar of 95 per cent, a maximum AC charge efficiency of 94.4 per cent and a discharge efficiency to AC of 94.5 per cent1. The company states this is "a substantial difference over some low-voltage systems, which operate at around 75%"1.
The inverter runs at battery voltages below 48V. Solis says such systems "require less complex monitoring and balancing than high-voltage systems"1. It also states that "the modular design also allows for easy expansion, enabling users to start small and add capacity as needed without costly upgrades"1.
Sandy Woodward, Solis Europe general manager, said:
"As more people look to take control of their energy usage, low-voltage solutions are becoming the preferred choice for residential and small commercial markets. They offer a unique blend of affordability, scalability, and safety that high-voltage systems can't easily match."
The announcement gives no UK price, no confirmed UK availability date and no list of compatible battery models. Those details have not been reported1. Solis states that the product joins its existing low-voltage range, which it says is now a significant portion of its portfolio1. The company was established in 2005 and is listed with stock code 300763.SZ1.
Why it matters for households
A hybrid inverter combines the solar inverter and the battery interface in one unit, so a home can add storage without a second box on the wall. The low-voltage design matters for how a system is put together: batteries wired below 48V avoid the higher-voltage architecture used by some competing home battery systems, and Solis presents that as simpler and safer to monitor and balance1.
The efficiency figures are the practical claim. Round-trip losses decide how much of the solar a household stores is available later in the evening, and Solis contrasts its 94 to 95 per cent figures with low-voltage systems it says run at around 75 per cent1. That comparison is the manufacturer's own and covers unnamed products.
The 8 to 15kW span and the modular expansion described by Solis point to a system that can be sized up over time rather than replaced, which affects how far a property can shift its electricity use away from the grid. Solis is an established string inverter maker, and its Solis inverter range is already sold in the UK, though this specific model's UK route to market has not been set out1.
What happens next
No UK launch date, pricing or installer availability has been announced1.
