The immerSUN is our ‘state of the art’ energy saving device. It helps you to self-consume the green energy produced by your microgeneration system, and is compatible with all renewable generation technologies, including solar PV, wind turbine and hydro systems.
The device is essentially an automatic power controller that diverts surplus power to a designated load, normally a hot water heater, to save energy and minimise your utility bills.
Compatible with all inverters, smart meters and energy monitoring systems, the immerSUN boasts an extensive range of additional features. This controller really is the perfect addition to any PV or wind turbine installation.
Once installed, the next-generation system will reduce an average household's energy bill by up to £250 per year by diverting microgen-generated electricity directly to an immersion heater, storage heater, and/or electric underfloor heating.
This helps users to significantly reduce utility bills, lower mains reliance and improve the eco credentials of their property, without affecting FiT payments.
Tracks surplus power and diverts this energy to the load
trusine technology for fast and smooth automatic power adjustment
Clear graphical backlit LCD display
Indicates current import/export power levels as well as diverted power to the heater
Savings are accurately reported for the day and each month as well as the total savings
No need to change the existing immersion heater
Built-in 7-day programmable boost timer
Savings can be displayed in several currencies as well as kWhs
Optional wireless current sensor
Manual boost function for both heater outputs
Integral multi-function relay
Up to 5 immerSUN units can be linked using wireless technology, therefore, the total surplus of around 15kW can be consumed on each phase if required
Fully short circuit protected in case of load fault
Power factor correction
Soft starting to avoid power surges and extend heater life
Complete CE product approvals and full EMC compliance
We have found that probably the best on the market is the ImmerSUN 2. We have installed countless units, and they have one of the best support / backup teams as well.
Do they work - yes there are lots of threads on here discussing the benefits.
Immersions only? No, any resistive load, we have connected them up to panel radiators, oil filled radiators, as well as immersions - they need to be 'dumb' though, i.e. no electronic controls.
Can they do even more? YES! (well some can )
A couple of the units, the ImmerSUN included can be set with thresholds and delays to switch on units that cannot cope with variable power being fed to them e.g Heat Pumps, they can be set when they reach an export trigger level to switch on that load, and to avoid excessive cycling they can then be configured with minimum on and minimum off times.
