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.
eddi Power Diverter
A premium diverter that intelligently routes surplus PV to your immersion heater. Smooth power control protects circuits while maximising on-site energy use.
- Monitors export and diverts excess to hot water
- Proportional control for stable, quiet operation
- Supports multiple heating loads / priorities
- Clear status display and neat wall enclosure
iBoost Power Diverter
A dependable, cost-effective diverter for households with a cylinder. Prioritises hot water before export to the grid, helping reduce imported energy for daily use.
- Automatic surplus PV detection & diversion
- Simple local controls and clear indicators
- Compatible with common immersion elements
- Low-profile wall unit for utility spaces
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.
