SolarEdge Free Optimiser Promotion

solaredge power optimiser s440

We are pleased to announce an exciting promotion with SolarEdge that dramatically reduces the cost of residential systems. These substantial savings make SolarEdge’s residential solutions one of the most cost effective on the market. You will receive a FREE S440 optimiser for every kilowatt of residential inverter purchased (1ɸ or 3ɸ) ranging from 3 to 10 kW.

This limited-time promotion reduces the cost of a SolarEdge residential system by up to 17%. This promotion also extends to the SolarEdge Smart Panel Systems. For example: when you buy a 10kW inverter and 30 smart panels, we’ll discount the panels by the cost of 10 x S440s.

SolarEdge promotion benefits

Provide your customers with the lifetime benefits of a SolarEdge DC-optimised system for no more than the price of a standard string system!  Note that S440 Optimisers are now compatible with panels up to 480W, offering a highly cost-effective solution for most modules on the market.

S440 Optimiser benefits for installers and homewoners

  • More power: SolarEdge systems generate more power immediately, with a minimum 2% yield advantage. This benefit grows year on year for the life of the system.
  • Safer: SafeDC and Sense Connect technology ensure top-notch safety and emergency shutdown capability.
  • Scalable: Unique system architecture allows for scalable growth to meet future energy needs.

*Promotion only valid for purchases of complete SolarEdge systems comprising residential inverters and the required number of optimisers (based on 133% oversizing).

Cost of the optimiser is reduced from Smart Panel costs when using the SolarEdge 415W Smart Panel

This offer applies to all residential single and three-phase inverters ranging from 3 to 10kW.
