WHY SOLAR IBOOST+
GET MORE FROM THE SOLAR YOU ALREADY GENERATE
1
Cut Water Heating Costs
Use free surplus PV for hot water and rely less on gas, oil, or peak-rate immersion.
2
Self-Consume More Solar
Divert export into stored heat automatically as generation and household use rise and fall.
3
Stay in Control
On-screen savings readouts, timed grid heating, and a boost button when you need hot water
sooner.
HOW IT WORKS
THREE SIMPLE STEPS
01
YOUR PANELS GENERATE
Solar PV powers the home first. Anything left over is normally exported to the grid.
02
CLAMP & SENDER SPOT THE SURPLUS
A clamp at the meter detects export. The wireless sender tells the iBoost+ when
spare power is available.
03
IBOOST+ HEATS THE CYLINDER
The controller next to your tank modulates power to the immersion in line with
export — only surplus energy, not grid draw for solar heating.

Fantastic service from start to finish. Spoke to AJK after speaking with a few solar companies and these guys went above and beyond the whole way. The team were polite, answered all our questions and done a fantastic job. Highly recommended.
