Solis S6 15kW three-phase HV hybrid inverter

At 15kW, the S6-EH3P15K-H tops the high-voltage side of our Solis S6 three-phase hybrid range. It is the unit for commercial and heavy domestic storage work, and for contractors who standardise a pipeline of sites on a single inverter platform.

Description

Standardising on one model pays off across a run of jobs: one set of spares, one commissioning routine, one part number on every purchase order. The 15kW S6 gives that anchor at the high end of the range, with the 12kW and 10kW three-phase hybrids beneath it for smaller sites. Pricing works the wholesale way here, ex-VAT and identical at any volume, which makes multi-site tenders easier to cost before the survey stage.

What it pairs with

Build the storage side with the Solis Stackable High Voltage BMS, and meter larger boards with the Solis 3phase Meter DTSD1352 and its 150A CTs. Where export limits apply, the Solis Export Power Manager EPM3-5G-PRO is the three-phase control option in this catalogue. Module counts and pairing vary by model and firmware revision, so check the current Solis compatibility list.

Three-phase only, and intended for high-voltage battery stacks. The battery, BMS and metering are all separate items. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Solis SOL-S6-EH3P15K-H buying questions

You see the ex-VAT trade price directly on the page rather than behind a login. VAT is added at 20% when we invoice. Buy one for a single site or a batch for a rollout: the unit price does not move, and there is no minimum spend.
By parcel courier: with no cells inside, an inverter is not dangerous-goods freight, so no pallet slot or kerbside handling is needed. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment. Batteries on the same project ship under their own freight terms.
Out of stock at the last catalogue update, and the count on this page comes from the live stock feed rather than a manual list. In stock means in stock; if the number reads zero, the trade desk can tell you the restock position for this part number.
UK trade buyers with a verified account: limited companies verify with a Companies House number, sole traders with a UTR, MCS or scheme number. No trade minimums — one unit at trade price, no annual-spend tiers.
