All Products, Solar Inverters, Solis, Solis Single MPPTSolis 2.0kW Mini S6 Solar Inverter (S6-GR1P2K-M-DC) (1 MPPT)
The all new Solis 2.0kW Mini S6 Series grid-tie solar inverter has a compact and lightweight design for easy installation. It is fan-less and therefore produces minimal noise (less than 20 dBA.)
The inverter is compatible with high-efficiency modules and bi-facial modules, so is perfect for small residential installations.
Features of the Solis 2.0kW S6 Mini Solar Inverter:
- Super high frequency switching technology with maximum efficiency of 96.6%
- DRM (Demand Response Mode) integrated and backflow power control function for smart grid requirements.
- Wide voltage range
- Intergrated Export Power Manager (EPM)
- Integrated AFCI (DC arc-fault circuit protection)
- Integrated DC switch for emergency shut-down of PV power or safe PV maintenance
- IP66
- Compact design
- Warranty: 5 years (option to extend to 10 years or 20 years.)
- Startup Voltage: 90V
Manufacturer Part Number: S6-GR1P2K-M-DC
This is the integrated DC switch version. This means you do not require an external DC Isolator (though, if you already have one it is not an issue. You can simply disable one of them!)
WiFi Monitoring:
For monitoring you can add a WiFi Dongle which can be purchased HERE or by selecting the add-on below. This enables you to make use of the Solis Cloud Remote Monitoring Platform.
Warranty
Solis Inverters come with a 5-year warranty as standard. This can optionally be extended to either 10-years or 20-years by purchasing a Warranty Extension. +5 Years | +15 Years
Note to end users:
Can end-users purchase this product to save money on the cost of a replacement inverter? Yes, of course! Simply purchase the inverter and arrange for a local qualified electrician to install the unit for you (should be a 1-2 hour call-out). By sourcing the inverter yourself, you can make a huge saving on the prices quoted by installation companies for supply and fit services.

30m Solar Panel Bird Exclusion Kit
Use this 30m Solar Panel Bird Exclusion kit to prevent pigeons and other birds seeking shelter and roosting underneath your solar panels.
The Enviroguard Bird Mesh is more permanent and safer than nylon pigeon netting in which birds can get trapped when it degrades. The initial outlay is balanced out by lower maintenance costs as it’s easier to remove and refit during routine inspections.
This kit is recommended by pest control experts to prevent birds from nesting under your solar panels.
The Solar Panel Bird Exclusion Kit includes:
- 30m Galvanised Solar Panel Weld Mesh Roll
- 60 Solar Panel Mesh Clips
- 1 Standard Wire Cutter
- 1 Pack Stainless Steel Corner Ties
