Power Diverters

Maximise self-consumption by sending surplus solar to hot water. Diverters monitor export and route excess energy into an immersion heater—cutting bills and making better use of your PV.

Do I need an immersion heater?

Yes. Diverters heat water via a cylinder with an immersion heater. If you have a combi boiler (no hot water cylinder), you’ll need a suitable cylinder with immersion to use a diverter. System or heat-only boilers that already feed a hot water cylinder are ideal—just confirm the immersion rating and thermostat are compatible.

Immersion Heater & Cylinder

Diverters require a cylinder with an immersion heater (typically 2–3 kW). We verify rating, thermostat and wiring so the diverter can modulate power safely and efficiently.

  • Works with vented or unvented cylinders (suitably specified)
  • Check immersion rating, thermostat and safe isolation
  • Combi systems need a cylinder added to participate
  • Neat, compliant wiring and labeling as standard

How it works

1) Measure export

A clamp sensor measures when PV production exceeds household demand.

2) Modulate power

The diverter proportionally sends surplus energy to the immersion element.

3) Prioritise hot water

Water is heated first; only true excess is exported to the grid.
