Solis 6kW S6 Dual MPPT Single-Phase Grid-Tie Inverter with Integrated DC Isolator
The Solis 6kW S6 is the largest single-phase inverter in the Ginlong Solis Series 6 dual MPPT range, rated at 6,000W. This transformerless grid-tie inverter accepts up to 9,000W of PV input across two independent MPPT trackers, each supporting 14A maximum input current for compatibility with high-efficiency and bifacial modules. Delivering a maximum efficiency of 97.7% and Euro efficiency of 97.1%, the S6 6kW is housed in an IP66-rated enclosure with natural cooling. The unit ships with an integrated DC isolator, integrated AFCI arc-fault protection, and a built-in Export Power Manager. Manufacturer part number: SOL-6.0-S6-DT-DC (MPN: S6-GR1P6K-DC). Available from DECO Group, a UK-based solar wholesaler for professional trade installers.

Key Features
- Super high frequency switching technology delivers a maximum efficiency of 97.7% and Euro efficiency of 97.1%.
- Dual MPPT design with precise MPPT algorithm enables independent tracking across two strings for improved energy yield on split or multi-orientation arrays.
- 14A maximum input current per string, compatible with high-efficiency and bifacial modules.
- Wide MPPT voltage range of 90V to 520V with a maximum PV input voltage of 600V and start-up voltage of 120V.
- 9,000W maximum PV input provides significant oversizing headroom for higher annual yields.
- Integrated AFCI (DC arc-fault circuit protection) proactively reduces fire risk on the DC side.
- Integrated DC switch provides emergency shutdown capability and safe isolation for PV maintenance.
- Export limitation built in via the integrated Export Power Manager (EPM). Requires a CT clamp, sold separately.
- DRM (Demand Response Mode) integrated for smart grid compliance.
- IP66-rated enclosure with natural cooling for reliable outdoor installation.
- RS485 communication with optional S3-WIFI-ST WiFi data logging stick for remote monitoring.
System Compatibility
- Compatible with high-efficiency and bifacial PV modules up to 14A per string.
- Export limitation requires a CT clamp (not included). For installations where the inverter is within 10m of the incoming power supply, use CT part number SOL-CT-100A-10M. A firmware upgrade to the latest version is required for this CT to function.
- For installations where the distance from inverter to incoming supply exceeds 10m, use the Solis Export Power Manager (SOL-EPM1-5G) instead.
- Optional S3-WIFI-ST WiFi data logging stick available for real-time remote monitoring via SolisCloud.
Installation Notes
- IP66-rated enclosure allows installation in exposed outdoor locations without additional weatherproofing.
- Natural cooling design with no moving parts, reducing long-term maintenance requirements.
- Dimensions of 310 x 543 x 160mm (W x H x D). At 14.3kg, the unit is manageable for a single installer but may benefit from assistance at awkward mounting heights.
- Four pairs of MC4 connectors included for direct connection to PV string inputs.
- Must be installed by a qualified electrician or technician. All installations must adhere to local wiring regulations and standards.
Warranty
- 5-year standard manufacturer warranty.
Common Questions
- What is the maximum PV input for the Solis 6kW S6 Dual MPPT?
- The Solis 6kW S6 accepts up to 9,000W 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 6kW S6?
- The inverter measures 310 x 543 x 160mm (W x H x D) and weighs 14.3kg.
- What CT clamp is needed for export limitation on the Solis 6kW S6?
- For installations within 10m of the incoming power supply, use the SOL-CT-100A-10M (firmware upgrade required). For distances greater than 10m, use the Solis Export Power Manager (SOL-EPM1-5G).
- Is the Solis 6kW S6 the largest single-phase inverter in the S6 range?
- Yes. The 6kW S6 (SOL-6.0-S6-DT-DC) is the highest-rated single-phase inverter in the Solis S6 dual MPPT series, accepting up to 9,000W of PV input. For larger single-phase installations, consider the Solis S6 range in higher power classes where available.
