Solis S6 2.5kW dual-MPPT inverter
The S6 2.5kW dual tracker answers the awkward small roof: two orientations, a dormer split, or shading down one side. Two MPPTs at 2.5 kW let each string work independently instead of forcing the whole array onto one tracker.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Small roofs are rarely tidy, and a single-tracker inverter makes an untidy roof expensive: mismatch on one string drags down the lot. Splitting east and west, or clear and shaded, across two MPPTs keeps each side earning what it can. That is the whole case for choosing this over the Mini at the same rating, and it is a strong one on terraced and cottage work. The DC isolator ships with it, and the S6 commissioning routine is unchanged, so the extra tracker costs nothing in site time.

What it pairs with
The dual-tracker S6 line continues upward through the 3 kW (SOL-3.0-S6-DT-DC) and 3.6 kW (SOL-3.6-S6-DT-DC) sizes when a survey grows. On accessories, add a Solis logging stick, 4-pin or USB fitting confirmed on Solis's pairing list, and the 100A current transformer for the 4G, 5G and S6 range (SOL-CT-100A-10M) for export sensing.
Single-phase only. Rated at 2.5 kW across its two trackers. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
