Safety Notes
Potentially dangerous High Voltages are present and therefore this equipment
should only be installed by a qualified person.
Connect the equipment according to the correct IEE regulations and separate all
wiring according to IEC1010.
Make sure all screw terminals are tight before you switch the equipment on. (The
terminal screw is rated 0.5N•m torque)
Do not touch any circuitry after you have connected the equipment, due to
potentially lethal voltages on the circuit board or connector terminals.
Equipment designed for Pollution – Degree 2 environments only. This means you
must install it in a clean, dry environment.

Overview
SOLARIMMERSION IV is an intelligent surplus power control system for your PV system. It diverts
surplus power which would normally be exported to the grid. When the unit is connected to an
immersion heater, it can heat water for free using the surplus power.
SOLARIMMERSION IV - Highlights:












Heats water using surplus power from all sorts of micro-generation systems (wind turbines,
hydro power)
Keeps exported power as close to zero as possible by adjusting power levels to the immersion
heater.
Single sensor clip.
LCD display for easy control and management of the unit
No need to change immersion heater or the tank.
No manual intervention required to use surplus power.
Built-in override and boost timer functions to an immersion heater manually if required.
Low threshold levels meaning, less wasted power.
Diverts as little as 20W of surplus power
Built-in multifunction relay for Second load.
Internal thermal protection
Multiple loads available

3. Installation
Mounting
To keep the installation quick and easy, we recommend that SOLARIMMERSION IV is installed near
to the consumer unit as most of the connections required can usually be found there.
When choosing a suitable place to install SOLARIMMERSION IV, the following should be
considered:






Near the main incoming mains supply of the property
Access to the immersion heater supply cable (normally in the consumer unit)
Access to suitable supply via 16A MCB or 13A fused outlet
Ease of access and visibility of the SOLARIMMERSION IV LCD Screen and control buttons
Good ventilation to keep air flowing through the unit – at least 100mm around the unit.
Suitable cable access point location – through the top of the unit
Secure the SOLARIMMERSION IV to the wall with the two screws or using suitable fixings for the
surface type.
Electrical Installation
ATTENTION!
Electrical connection should only be made by a qualified person.
Please do not attempt to install SOLARIMMERSION IV unless you hold such qualifications or are
an experienced electrician. Alterations to fixed wiring and/or opening the consumer unit may
be required – risk of death by electrocution.
Locate the most appropriate cable access point at top of the unit to make connections to the unit
according to the wiring diagram.
Loads
The proportionally controlled primary and secondary loads connected (alone or combined)
should not exceed 3kW. The load should not include digital circuits, as they may be affected by
the modulated output from the SOLARIMMERSION IV
The relay terminals could be used to drive small inductive or resistive load when LOAD 2 is
enabled.
6
Terminals
ATTENTION!
Make sure the wiring cables are securely connected and fully tightened with the rising clamp
terminals. (The terminal screw is rated 0.5N•m torque) Failure to do so can result in fire or the
SOLARIMMERSION IV unit being damaged.

Wiring Diagrams & Software Setup
Single Load System
For single heater control, no relay terminal wirings are required as the secondary load options is
not used.
The default factory settings of the SOLARIMMERSION IV are optimised for a single heater
configuration. This keeps the installation simple, as the only menu setting required is setting the
time.
The default factory settings of the switch is configured for single heater system. So no setting
changes are required other than setting up the time. If any settings were changed before, please
do a factory reset of the switch via the menu controls.
8
Dual Load System
With a single Load system, the surplus will flow back to the grid once the water is hot and the
thermostat cuts off. This could be avoided using a dual heater system. The secondary load (LOAD 2)
will be turned on when the primary load's (LOAD 1) thermostat is cut off. This improves the
efficiency of the system.

Remarks
Enable the secondary load
How long the secondary load should run
before switching back to primary load
Example Scenario for dual system:
The secondary load will be activated 3 minutes after the thermostat in the immersion cuts off &
there is surplus power.
1. The primary load thermostat cuts off
2. The system has a surplus of 1000w at the point when the primary load cuts off
3. The system still maintains a 1000W surplus after 20 minutes
If the 'Load time' is set to 60, the unit will deactivate LOAD 2 after 1 hour and activate LOAD 1. If
the LOAD 2 thermostat is still at 'cut off' stage, the LOAD 2 will be activated after 20 minutes and
the whole cycle will continue.
Sensor Clip Installation
The correct installation and positioning of the current sensor clip is very important for the efficient
operation of SOLARIMMERSION IV. Wrongly installing the sensor clip could result in importing of
power and the user incurring additional costs for electricity.
The sensor clip should be installed at the main incoming grid supply to the building which could be
from the utility/electricity meter. (Please note - it is Utility/Electricity meter NOT the PV generation
meter). Close the clip around the Live or Neutral cable from the utility/electricity meter. Please
ensure the sensor clip is positioned nearest to the utility/electricity meter as possible. (Only open
a consumer unit if you are qualified to do so or are an experienced electrician).
If there is more than one consumer unit, the clip must be positioned at the primary income source
– before it splits.
IMPORTANT
SENSOR CLIP HAS TO BE ON THE UTLITY/ELECTRICITY METER TAILS AND ALWAYS ENSURE THE
CLIP IS CLOSED SECURELY AROUND THE CABLE!
Connect the clamp wire to the terminals inside SOLARIMMERSION IV. If the sensor clip cable is not
long enough it can be extended up to 50m but this must be done using a double twisted pair cable
in order to stop any possible interference and a firm connection to the original cable is required.
Try to keep the extension cable as short as possible, as the signal strength from the sensor is very
low.

4. Installation Settings
Once the unit is wired, SOLARIMMERSION IV has to be configured with the parameters required
for the particular installation type used. By default, for simple installations with a single heater, the
only configuration requirements are listed below.
Follow the steps below to calibrate and setup the unit.
Step 1: Turn off the PV or micro generation system. This is to make sure power is only imported,
which is essential for sensor clip calibration.
Step 2: Turn on SOLARIMMERSION IV unit.
Step 3: Turn on a high load like a kettle or a 2kW heater to make sure power is imported and wait
for 5 seconds.
3a: If the sensor clip is installed correctly, the display will be as below with the ASTERISK
symbol ( ) Blinking.
3b: If the display is as below, then you have to swap the wiring on the CT sensor terminals.
Once the terminals are swapped, restart the switch and make sure the display is as picture
3a.
Step 4: Set the correct time & software settings according to the wiring mode selected. (Please
see section 5. Using Menu Controls and "Internal Clock - setting the time" in Appendix 1)
Step 5: Turn the PV inverter back on. That completes the installation and SOLARIMMERSION IV
should now start to divert any surplus power if available to the immersion heater or the connected
load.
