The immerSUN T1060 is a ‘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 and wind
turbines. 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. This
controller really is the perfect addition to
any PV or wind turbine installation.
BENEFITS OF USING AN IMMERSUN UNIT
Use your free electricity when you're out Speedy payback
Increase your return on investment Accurate data monitoring
A solar controller that is simple to install
Use your free energy and still get paid
Higher efficiency reduces your energy bills
Built-in hot water timer with added Boost function
IMMERSUN RETROFIT: Smart energy management in the home
CASE STUDY: Haslingden, Lancashire
Sustainable Energy Systems Ltd installed an
Evance R9000 5kW wind turbine at the site in
2012. We also retrofit an immerSUN which is a
perfect accompaniment to the wind turbine as
it diverts surplus electricity into the customers
towel warmers via a bespoke domestic water
heating system. The immerSUN monitors the
electricity produced by the wind turbine and
minimises the amount exported to the grid by
diverting it automatically. It is a really smart
method of self-consumption which saves
money associated with heating water. It also
measures and records the savings made and
the display lets us view the daily, weekly,
monthly, annual and total savings.
FACTS & FIGURES
Wind turbine average annual energy production (AEP) = 10,500 kWh
Average purchase price of electricity = 16p per kWh
immerSUN average diversion figures and savings:
Monthly = 349.8 kWh (£55.97)
Yearly = 4,197.5 kWh (£671.60)
Proportion of wind turbine AEP diverted by immerSUN = 40%
“The immerSUN was simple to install and is
recommended as a really effective way to
use the spare power from your wind turbine
or solar PV system. We see figures of
11.5kWh going into the hot water on a
typical day, effecting an impressive
payback and we are making significant
savings thanks to the immerSUN. It is a
fantastic piece of equipment, we are really
impressed with the results and recommend
the immerSUN and Sustainable Energy
Systems Ltd.”
Mr Mark Allcock, Haslingden
CASE STUDY: Sustainable Energy Systems Ltd, Great Eccleston CASE STUDY: Little Eccleston, Lancashire
Committed to embracing sustainable
solutions, we have installed three
immerSUN devices across the
three-phase supply at our office to
boost self-consumption of the energy
generated from our 20kW solar PV
system. These make the most of the
surplus energy which remains from
the PV system once the office’s
electrical demands are met, by
diverting the surplus energy to
immersion heaters, rather than
export the energy to the grid. The
immerSUN devices effectively turn
the solar PV system into a solar hot
water system when the office is not
using all of the generated electricity.
This provides heating which reduces
our energy bills as we are not
purchasing as much energy from the
supplier.
FACTS & FIGURES
Solar PV system average annual energy production (AEP) = 13,700 kWh
Average purchase price of electricity = 13.5p per kWh
immerSUN average diversion figures and savings:
Monthly = 326.7 kWh (£44.10)
Yearly = 3,920.1 kWh (£529.21)
Proportion of PV AEP diverted by immerSUN = 29%
“Sustainable Energy Systems Ltd has invested in installing immerSUN units at our own
premises following a review of a significant number of the competitive products on the
market. The immerSUN unit is well-suited for our office and warehouse premises. The
unit has proven to be extremely efficient at diverting the unused electricity generated
by the solar panels. The excess power is delivered to a buffer store built into our ground
source heat pump system. The power supplies a three phase immersion heater and the
heat generated is distributed to the underfloor heating and office radiators. All the
energy is utilised which results in large savings. In the last two years the immerSUN units
have diverted over 7,000kWh, creating a saving of over £800 to the business.”
Mr Jon Kemp, Sustainable Energy Systems Ltd (Great Eccleston)
In 2011, Sustainable Energy Systems Ltd
installed a 4kW solar PV system comprised
of three ground mounted arrays which
provides energy to power the customer’s
farmhouse. An immerSUN was installed in
2014 in order to maximise the
self-consumption of the electricity
generated by the PV system. The
immerSUN automatically directs any
excess generated electric which is not
used by the house to the immersion heater
in the water cylinder, supplying the
property with hot water at minimal cost.
The customer benefits from the installation
as they are able to use their ‘free’
electricity when they are away from home
and can use up to 100% of their generated
electricity whilst still receiving the FIT
revenue for the 50% deemed export.
FACTS & FIGURES
Solar PV system average annual energy production (AEP) = 4,170 kWh
Average purchase price of gas = 4p per kWh
immerSUN average diversion figures and savings:
Monthly = 134.1 kWh (£13.07)
Yearly = 1,609.7 kWh (£64.36)
Proportion of PV AEP diverted by immerSUN = 39%
“The immerSUN was recommended and installed by Sustainable Energy Systems Ltd as
a very effective way of utilising electricity product from my 4kw solar PV array,
especially during periods when at work. As the tank is quite large (330 litres) this is an
ideal medium to store the energy produced. I have been very pleased with the results
as an average of 1,609kWh of electricity has been diverted to the heating of hot water
per year. This has resulted in the gas boiler being used less for the heating of hot water.
The unit is very simple to use and once set up gives useful information in relation to
electricity diverted and savings made. I would recommend one of these units especially
if you feel you are not fully benefiting from the electricity being produced by your wind
turbine or PV array.”
Mr Rick Brown, Little Eccleston
