1. with IEE wiring regulations2. It is useful to occasionally look at the flashing LED to check that the device is continuing to function correctly The LED can indicate one of five operating modes as follows MODE 1 IMPORT When the LED flashes ON for half a second then OFF for half a second Solamiser is detecting import energy This typically occur after dark When you are consuming electricity from the grid The immersion heater and storage heater if fitted are is always switched off in MODE 1 MODE 2 EXPORT When the LED flashes ON for two seconds then OFF for two seconds Solamiser is detecting export energy This means that excess energy from your solar panels is being sent back to the grid This will occur when your immersion heater and storage heater if fitted are both switched off Solamiser V3 User Manual MODE 3 DIVERTING TO IMMERSION HEATER When producing single pulses Solamiser is detecting that virtually no energy is flowing back to the grid Nearly all excess electricity being generated by your solar panels is being used by both your house and your immersion heater Variable amounts of energy are diverted to your immersion heater to maintain this balanced state For example if you turn on the TV the amount of energy going to the immersion heater will reduce by the amount used by the TV If the sun goes behind a cloud Solamiser will reduce power to the immersion heater to maintain balance The pulse rate of the LED in MODE 3 reflects the a

9. of Solamiser Solamiser V3 User Manual COMMISSIONING SOLAMISER Solamiser senses the current flowing through the house s main incoming power cable at a point between the main electricity meter and the consumer unit This is accomplished with a non invasive current clamp There is no need to disconnect the sealed mains cable In addition to sensing the amount of current passing between the main electricity meter and the consumer unit the current clamp also senses the direction of the current It is therefore important that the current clamp is mounted the right way round on main incoming cable otherwise the sensing direction will be reversed and will result in excessive energy use Check where the solar microgeneration system connects to the mains power system This is usually at the hot side of the consumer unit s main isolator switch as shown on the diagram above The current clamp must be placed around the main incoming cable L core only nearer to the main electricity meter than the solar connection point to ensure solar current has already been algebraically summed with mains incoming current at the current clamp s point of measurement Solamiser V3 User Manual To get the current clamp the right way round proceed as follows a Plug the current clamp s 3 5mm Jack plug into the Jack socket on the left hand side of Solamiser It is safer to plug in the current clamp before clipping round the mains cable Clip the curr
