Solis 3kW S6 Dual MPPT Single-Phase Grid-Tie Inverter with DC Isolator (EU, No Export Limitation)
The Solis 3kW S6 EU is a single-phase, dual MPPT grid-tie inverter rated at 3,000W from the Ginlong Solis Series 6 range. This EU variant (SOL-3.0-S6-DT-EU-DC) ships without an export limitation function and includes CTs only; a separate meter is required to enable export limitation. The transformerless inverter accepts up to 4,500W of PV input across two independent MPPT trackers, each supporting 14A maximum input current for compatibility with high-efficiency and bifacial modules. Maximum efficiency is 97.1% with Euro efficiency of 96.7%. The unit includes an integrated DC isolator, integrated AFCI arc-fault protection, and an IP66-rated enclosure. Also referenced as S6-GR1P3K-DC. Available from DECO Group, a UK-based solar wholesaler for professional trade installers.

Common Questions
- What is the difference between the SOL-3.0-S6-DT-EU-DC and the SOL-3.0-S6-DT-DC?
- The EU variant (SOL-3.0-S6-DT-EU-DC) does not include an export limitation function and ships with CTs only. A separate meter is required to enable export limitation. The standard variant (SOL-3.0-S6-DT-DC) includes built-in export limitation via the integrated EPM, though a CT clamp is still required and sold separately.
- What is the maximum PV input for the Solis 3kW S6 EU Dual MPPT?
- The inverter accepts up to 4,500W of PV input power across two independent MPPT trackers, with a maximum input voltage of 600V and 14A maximum current per string.
- What are the dimensions and weight of the Solis 3kW S6 EU?
- The inverter measures 310 x 543 x 160mm (W x H x D) and weighs 11.2kg.
- How many MPPT trackers does the Solis 3kW S6 EU have?
- The Solis 3kW S6 EU features a dual MPPT design with two independent trackers, each supporting up to 14A input current. This allows two separate PV strings to be optimised independently for split or multi-orientation roof layouts.
