1. The electrical installation of this device must only be undertaken by a suitably trained
and qualified electrician; all local safety standards must be observed. All work must
satisfy Building/IEE Wiring regulations in force at the time.
2. Solar iBoost+ is suitable for heating water tanks with up to two immersion heaters rated
up to 3kW each which MUST include a working thermostat.
3. There should be NO electronic controls between the Solar iBoost+ and the immersion
heater, only direct connections to the immersion and mechanical thermostat are
suitable for Solar iBoost+.

should be NO neon lamp on the switch.
Thank you for purchasing a Solar iBoost+.
Solar iBoost+ Features.
Up to two immersion heater connections, when the first immersion heater is
satisfied the energy flows automatically to the second immersion heater
Manual Boost and programmable Timed Boost (eg. For economy settings)
A single, battery powered, wireless sender with measurement clamp
Displayed energy saving information
Up to 3kW immersion heater capability
Solar iBoost+ is pre-programmed for wireless connection to the optional iBoost+
Buddy home energy monitor
These instructions provide information on the installation, operation and
programming of the unit. Please keep this booklet safe for future
reference.
The Solar iBoost+ is designed to be used in conjunction with micro-generation systems,
e.g. solar PV, where surplus energy generated can be stored within a domestic hot water
cylinder in the form of hot water. By monitoring the amount of energy being exported to
the National Grid the Solar iBoost+ unit will divert energy into an immersion heater when
the energy generated exceeds the amount of energy consumed within the property. Solar
iBoost+ controls the energy delivered to the immersion heater in proportion to that
exported.
Before use, please read these instructions carefully

Pre-Installation
1. Read Checks Before Commencing Installation and ensure compliance.
2. Locate a suitably ventilated, flat and vertical surface close to the hot water tank to fix
the Solar iBoost+, observing all clearances shown on page 6. Positioning should be
convenient for running a cable from a fused spur to the Solar iBoost+ and on to the
immersion heater(s).
Connection
3. Hard wire the Solar iBoost+ in accordance with the selected wiring diagram on pages
7-9 following IEE Regulations or local regulations. Replace the terminal cover but do
not power up.
4. Connect the Measurement Clamp into the Sender and fit the batteries in the Sender.
Keep the Sender at 1-2m from the main unit. Do NOT press the button on the Sender.
5. Switch on the power supply to the Solar iBoost+ and a short start up procedure runs
until Water Heating Off is displayed.
6. Programme Time and Timed Boosts if desired, see page 15.
Locate the Sender
7. At the utility meter (NOT the Generation meter) place the Measurement Clamp over the
household main incoming live cable and latch into place. Note that the Clamp
must be installed on the utility meter side of any connector (or Henley) blocks.
IMPORTANT: the orientation of the clamp must be observed to ensure only
excess current is detected and used for water heating.
Commissioning
8. To commission, perform the tests shown in section 5.

Minimum clearance is 100mm all around. Do not allow airflow to be obstructed.
Fixing the Solar iBoost+
Positioning
The Solar iBoost+ unit is typically located close to the hot water tank (airing cupboard or
similar) and electrically connected between a fused outlet or MCB and the immersion
heater.
Rear Hanging Brackets
Fixing Screw Points
Use screws supplied or suitable screws for
the mounting surface.

2. Connecting the Solar iBoost+
Hard wire the Solar iBoost+ in accordance with the selected wiring options
on the pages overleaf.
Terminals allow the connection of up to 4mm² solid copper conductor or
multi-strand cable.
Ensure terminals are fully tightened and cable is clamped using the cable
clamps provided. Where necessary, invert the plastic cable clamp to provide
the correct grip.
Replace the terminal cover, do not switch on power at this stage (go to
section 3)
The Solar iBoost+ installation must be protected against overcurrent by connecting it via a
16A MCB or 13A fused outlet.
Remove the terminal cover, terminals are arranged as follows:

Where two immersion heaters are present, wire the heaters into the Solar
iBoost+ as shown below. It is important the upper most heating element in the
tank is connected to the HTR1 terminals so that this element receives heating
priority.
Dual Immersion Heater
Dual Immersion Heater Operation
The Solar iBoost+ automatically detects when two immersion heaters are connected.
As hot water is drawn from the upper part of the tank, it is important the heaters are
connected as shown so that the Solar iBoost+ can automatically give heating priority to
the top heater. Excess generation is diverted to the top heater until temperature is
reached and the heater thermostat opens. Solar iBoost+ then automatically switches to
the lower heater to continue to divert excess generation until the lower heater is also
satisfied and ‘Water Tank HOT’ is displayed.
When diverting to the lower heater the Solar iBoost+ will periodically (every 15 minutes)
switch to the top heater and the cycle of heating begins again. This maintains the
temperature in the upper part of the tank.
An indication of the current heater being supplied is shown on the ‘Heating by Solar’
display, see page 13.
This operating mode is the same whether diverting excess generation or in boost function.

The Sender unit has a Measurement Clamp that detects export current when correctly
fitted on the live incoming supply cable from the utility meter. The unit sends
measurements wirelessly to the Solar iBoost+ unit.
3. Assembling the Sender and Measurement Clamp
A DC mains power supply is available to
purchase separately.
Contact your supplier for details.
Fit the connector from the power supply
into the socket marked on the sender.
1. Fit the plug from the Measurement
Clamp wire into the Sender.
3. Switch on the power to the Solar iBoost+.
A set up procedure runs and the 2 devices
connect automatically, usually within 30
seconds. If necessary follow the instructions
for pairing on page 16.
Note: The Sender and Solar iBoost+ units are factory paired. Do not press the
button on the sender or pairing may be lost.
Assemble the Sender
Initialising
Please Wait
2. Fit batteries (included) or DC mains
power supply (supplied separately).
When fitting batteries or DC power supply
the sender should be at least 1-2m away
from the Solar iBoost+
