ENHANCED ENERGY
SOLAR POWER DIVERTER

How immersun works?

The immerSUN monitors the electricity which is about to be exported to the grid and diverts it to the immersion heater. It then automatically directs any excess generated electricity, not used by the house, to the immersion heater in the hot water cylinder.

If the load from the house increases, eg. the washing machine is turned on, the immerSUN will reduce the amount sent to heat water to help you maintain independence from the grid.

Benefits of using immerSUN
  • Use your free electricity when you’re out
    Our smart self consumption controller device for solar directs excess electricity to the immersion heater, storage heater, or electric underfloor heating.
  • Increase your return on investment
    Adding an immerSUN to your PV installation can increase your return of investment.
  • Speedy payback
    When using the immerSUN to heat water with PV we estimate you could achieve a payback on the unit of between 2-5 years.
  • A solar controller that is simple to install
    The immerSUN uses your existing immersion heater when using your solar panels to heat water and can take less than an hour to install
  • Use your free energy and still get paid

    Use up to 100% of your generated electricity and still get paid for any excess which is exported to grid.

  • Higher efficiency reduces your energy bills
    By using more of your free electricity you will make substantial savings on your power bill.
  • Built in hot water timer with added Boost function
    You have total control over your hot water with our advanced features like myImmerSUN remote monitoring.
  • Accurate Data Monitoring
    The immerSUN uses hard-wired, fixed installation methods (no batteries required) enabling accurate data reporting with no need to replace batteries.
