Connect the equipment according to the correct IEE regulations and separate all wiring according to IEC1010. Earth must be connected for safety and correct operation. A suitable means of isolating SOLARIMMERSION IV from both poles of the mains supply shall be provided. 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 and connector terminals. Fit top cover back before switching on the Mains. ...

Page 4: Overview
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 ... - Page 5 SolarImmersion Mark IV Weight/Dimensions Weight: 650g 200mm 150mm Mounting holes centre: 175mm 65mm Electrical Specifications Description Min Nominal Max Supply Voltage (VAC) 220 240 254 Supply Frequency 45Hz 50Hz 55Hz (Hz) Load Current (A) 13 Load Size (kW) 3 3.5 ...

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 ... - Page 7 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. Power Terminals Terminal Description O/P ( Load Out)*1 Output to the load, Max 3kW L (Live) *2 Main Live 240 V input supply from 16A MCB / 13A fused outlet N (Neutral) *2 Mains Neutral (All neutral terminals internally connected) E (Earth) * 3 Main Earth Relay Terminals Terminal Description NO Normally open relay terminal COM Common relay terminal NC Normally closed relay terminal All relay terminals are volt free and the maximum current is 16A The relay terminals may be used to directly switch mains loads on the same phase as the mains supply to the Solarimmersion IV. However, the external circuit must be considered to be Hazardous Live and insulated accordingly, irrespective of the actual external voltage present. Sensor Terminal ...

Page 8: Wiring Diagrams
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 ... - Page 9 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. ...

- Page 11 1. The primary load thermostat cuts off & there is surplus available. 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 ...

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. ... - Page 13 5. Using Menu Controls & Setting Time When you have turned on the unit the default home screen will appear as shown in the imagine below. (This is the screen you will return to every time you press the “ESC” button) Current time Load diverting indicator Sun symbol constant ‐ Current Load Surplus Energy available, This will be "LOAD divert active. 2"when the secondary load is activated.
