Solis has listed the S6-EH3P(30-60)K-H(21A) in its inverter catalogue, a three phase high voltage energy storage inverter that the manufacturer says supports PV input up to 100kW1. The entry appears on the company's product pages alongside its other hybrid, off-grid and grid-tied models1.
The catalogue describes the unit as "Three Phase | High Voltage" and states that it "Supports PV input up to 100kW, maximising solar utilisation"1. No efficiency figures, battery voltage range, backup output rating, price or availability date for this model appear in the listing1.
The new entry sits in a range that already includes smaller three phase high voltage storage inverters. The S6-EH3P(5-10)K-H is listed with a 50A/10kW maximum charge and discharge rating and support for unbalanced and half-wave loads on both the grid and backup ports, while the S6-EH3P(15-20)K-H is listed as generator-compatible for extended backup during grid outages and compatible with SG heat pumps1. At the larger end, the S6-EH3P(80-125)K10-NV-YD-H is described as supporting 100% three-phase unbalanced output and 200% PV input capacity1.
Solis also lists single phase storage models, including the S6-EH1P(3-10)K-L-PLUS and S6-EH1P(12-18)K03-NV-YD-L, both described as generator-compatible with 10 seconds of 200% overload capability, and the S6-EA1P(3.6-6)K-L AC-coupled inverter, which supports six time-of-use battery charging and discharging settings1. On the grid-tied side, the catalogue includes the S5-GR3P(12-25)K(21A) three phase inverter with 2 MPPT and 21A/32A/42A per MPPT at IP66 and C5 anti-corrosion level, and the S6-GR1P(8-10)K03-NV-ND single phase inverter with a 3 MPPT design for multi-facing roofs1.

Why it matters for households
Inverters in this power class are not the units typically fitted to a single UK home. A three phase connection is uncommon in domestic properties, and a device listed across a 30-60K band with PV input up to 100kW points to larger installations than a typical roof array and one home battery. For a household, the practical relevance lies in what the wider range shows about how storage systems are being specified: the same manufacturer offers single phase hybrid units from 3K upwards, three phase units from 5K, and models that combine solar input, battery charging and backup output in one box1. That combination is what allows a home to store its own generation and keep selected circuits running when the grid is down, rather than exporting everything it produces.
The catalogue gives no indication of how the new model would be configured in a domestic setting, and no UK-specific information such as certification, grant eligibility or installer availability is reported1. Households weighing storage options would need details that this listing does not carry, including battery compatibility, backup power rating and whether the unit is approved for connection in the UK. None of that has been reported.
What happens next
No launch date, price, UK availability or certification details for the S6-EH3P(30-60)K-H(21A) have been reported1.
