Solis S6 12kW three-phase HV hybrid inverter
Sitting between the 10kW and 15kW units, the S6-EH3P12K-H gives the Solis S6 three-phase hybrid range its 12kW step. It is aimed at installers running high-voltage batteries who find 10kW too tight for the array and 15kW more inverter than the job needs.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Sizing a three-phase storage job is mostly about matching the inverter to the array and the load without paying for headroom nobody uses. That is the case for the 12kW model: it carries designs that outgrow the 10kW unit without the jump to the top of the range. Because it shares the S6 platform with its siblings, wiring habits and commissioning routines carry over from job to job. Ex-VAT trade pricing applies throughout, with checkout behind a verified trade account and stock held in the UK.

What it pairs with
Its natural battery partner in this catalogue is the Solis Stackable High Voltage BMS, which anchors an HV stack. The Solis Meter 3PH Eastron V2 (with CT) covers three-phase metering, and a Solis data logging stick handles monitoring. HV battery stacking depends on model and firmware revisions, so confirm module counts against Solis's current stacking list.
A three-phase supply is required, and the unit is designed around high-voltage battery systems rather than low-voltage packs. Batteries and metering are separate line items. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
