Specs that matter

A 3 kW inverter for homes with panels on two roof faces. It takes 1.5 times its rating in PV, split across two independent trackers.

How the two trackers split the array

Each MPPT takes one string at up to 14 A (22 A short-circuit) and tracks between 50 V and 450 V. The whole unit starts at 60 V. A south-east face and a south-west face can differ in panel count and still each run at their own best point. Ten 450 W panels, six on one side and four on the other, reach the 4.5 kW recommendation.

In the carton

  • DC isolating switch integrated
  • Export power control, with DRM for smart-grid signals
  • Integrated AFCI, needs activating on commissioning
  • CT clamp for export limitation (sold separately)
  • Wi-Fi or GPRS logging stick

Grid notification

G98 applies

Rated at 13.0 A on 230 V, this is within the 16 A single-phase G98 allowance. Its G100 certificate, issued for SOL-3.0-S6-DT-DC, is in the Documents tab.

Complete the kit

  • Single-phase export CT

    100 A clamp with a 10 m lead for S6 single-phase models, required for the export limit to work.

  • GPRS logger

    Uses the mobile network instead of home broadband and is listed for the entire Solis range. Needs a SIM with data.

  • Warranty to 20 years

    The 15-year extension for S6 GR1PK inverters rated 2.5 to 6.0 kW.

What buyers ask

Do both strings need the same number of panels?

No. The two trackers are independent, so an uneven split such as six and four is fine.

What is the biggest string voltage it accepts?

550 V absolute maximum, with 450 V as the top of the tracking range.

How much current does it feed back?

13.0 A rated at 230 V, 15.7 A at most.

What do packs and pallets contain?

The S6-GR1P3K in fives, tens or a pallet of 16, the same model as the single. The savings table lists the per-unit prices.
