New-Build 1.8kW (4 Panels) Grid-Tie Solar Kit with 3.0kW AC Coupled Inverter and 5kWh Battery

  • Meets UK Future Homes Standard regulations for new builds while cutting running costs.
  • Store surplus solar in a 5kWh battery instead of exporting it all to the grid, with SEG export payments still available.
  • Complete new-build kit with all-black panels, PV inverter, 3.0kW AC coupled inverter, 5.12kWh battery, in-roof mounting and safety components.

Solar panels on new builds are now common to meet tightening energy regulations while cutting costs and adding property value. This 1.8kW grid-tie kit includes 4 all-black Canadian Solar panels, Solis 2.0kW PV inverter, protection gear and GSE in-roof mounting kit. Suits pitched roofs needing G98/G99 DNO approval.

The 3.0kW Solis S5-EA1P3K-L G5 AC coupled inverter and 5.12kWh Dyness PowerDepot H5B G2 LFP battery add on-site storage, helping you shift solar to evenings and backup essential loads during outages when used with a suitable system design.

Key Features

  • 4 × Canadian Solar 450W TOPHiKu6 all-black panels (22.5% efficiency) for discreet, high-yield new-build roofs.
  • Solis 2.0kW S6-GR1P2K-M PV inverter with 97.3% max efficiency and IP66 weather protection for outdoor or loft mounting.
  • Solis 3.0kW S5-EA1P3K-L G5 single-phase low-voltage AC coupled inverter for flexible retrofit or hybrid-style storage.
  • Dyness PowerDepot H5B G2 5.12kWh IP65 LFP battery for long life, high safety and indoor/outdoor wall or floor mounting.
  • BENY IP65 AC switch, RCBO and Emlite generation meter for safety and compliance in UK installations.
  • Hark G100 Export Limitation Scheme (if required by DNO).
  • GSE in-roof solar mounting kit for a neat, integrated appearance ideal for new-build housing.
  • Option 1: Marlec Solar iBoost diversion kit for hot water immersion heaters.
  • Option 2: Marlec heat pump control using the iBoost Heat Pump Interface (HPI) to prioritise low-carbon heating.

Applications

  • New-build homes needing Part L / Future Homes-compliant on-site renewables with in-roof PV and battery storage.
  • Small commercial units, home offices and small logistics buildings looking to cut imported energy and add resilience.
  • Developers wanting a pre-engineered kit that can be installed by trusted MCS partners with DNO approval.
