Page 6: Installation
1. Installation 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. 100mm 100mm 100mm 100mm Minimum clearance is 100mm all around. Do not allow airflow to be obstructed. Fixing the Solar iBoost+ Two hanging brackets and two lower fixing screw points are provided: Rear Hanging Brackets... - Page 7 2. Connecting the Solar iBoost+ 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: 220-240V 50Hz Max 3kW SUPPLY HTR 1 HTR 2 cut-outs for rear cable...

It is important the upper most heating element in the tank is connected to the HTR1 terminals so that this element receives heating priority.
- Page 10 3. Assembling the Sender and Measurement Clamp 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. Note: The Sender and Solar iBoost+ units are factory paired.
- Page 11 4. Fitting the Measurement Clamp At the utility meter (Caution! not the Generation meter) identify the live cable feed to the property’s consumer unit. Open the Measurement Clamp and remove any plastic packaging. Position the clamp around the cable observing the correct orientation as shown below. Close the Clamp and ensure that the latch is engaged.

Page 15: Set Time
Programming The programming function allows: Setting the time and date of the clock Programming of Timed Boosts when grid power is automatically switched on to heat the water. This feature can be used in place of existing timers. The Solar iBoost+ unit is programmed using push buttons A and B. - Page 16 Pairing the Sender Unit The Solar iBoost+ and Sender are supplied uniquely paired and should not require the following operation. However, if the signal becomes lost or a new pairing is required the following procedure should be performed with the sender positioned 1m or more from the Solar iBoost+. Press any button on the Solar iBoost+ to switch on the backlight.
- Page 17 Manual Boost Switches on full power to the immersion heater for the period of time selected. Note that electricity is drawn from the grid if the excess generation is too low. Press any button on the Solar iBoost+ to switch on the backlight. Each press of the Boost button adds 15 minutes to the boost time up to maximum of 2 hours.

Questions and answers
Since my Solar I-boost was installed in 2014, when I had no battery storage, I have had retrofit Pylon 2 x 3.5kWh batteries and then a new generation system installed with 3 x Fox EP5 5.18kWh batteries - ie a total BESS od 22.54 kWh x 90% = 20+ kWh of usable storage - and so my I-boost is only heating the water when I have SOC 100% = 22.54 kWh stored. But can I not leave my gas HW heating off and simply press the manual boost and use any available battery storage ??
