Powerflow FAZE ECO Single Phase Solar Immersion Diverter for Solar PV with 5 year Warranty. Alternative to Marlec Solar iBoost+

Increase your solar self consumption – the perfect balance of quality, performance and cost.

FAZE ECO solar controller automatically adjusts its power output to control, for example, an immersion heater, so any available export energy from solar is captured and stored as free hot water.

Renewable energy systems, such as solar PV panels, generate electricity based on sunlight availability, leading to mismatches between energy production and usage. Excess energy, often sent back to the grid, represents a missed opportunity for savings.

The FAZE ECO, a solar hot water diverter made in the UK, addresses this issue. It is designed for simplicity, featuring a power output display, full battery compatibility, and a manual boost button. The device efficiently redirects any surplus solar energy to heat water, utilizing the existing immersion element.

FAZE ECO is built to last, utilising the highest quality components. Our patented technology makes FAZE ECO the most efficient power diverter available. The core technology has been refined over the past decade to deliver class leading performance. This is backed by a 5 year hassle free warranty.

By converting excess solar power into thermal energy, the FAZE ECO helps reduce dependence on traditional energy sources and lowers utility costs. It’s an essential addition for homeowners looking to optimize their systems and achieve better energy utilization and savings.
