1. Introduction Thank you for choosing eddi. Of course, we think you have made an excellent choice and are sure you will be very happy with the features, benefits, and quality of your myenergi product. eddi is an automatic power controller. It ‘tracks’ available surplus power from a grid-tied PV or Wind turbine system and varies the power to your heater to match the surplus power, therefore ensuring all of the green energy is fully utilised.
. Overview Microgeneration systems such as Solar PV and small wind turbines are at their most efficient when the generated energy is consumed on-site rather than exporting it to the grid. This is what we call 'selfconsumption'. eddi is an energy management system for use with grid-tied PV or wind turbine systems. Excess energy from the microgeneration system is used to heat water or rooms rather than exporting it to the grid. A grid current sensor (supplied) simply clips around the incoming cable.

9. Operating Modes 9.1 Waiting for Surplus 9.2 Heating 9.3 Max Temp Reached 9.4 Boosting Page 10 of 24 eddi is waiting for surplus power from the microgeneration system. The house in the centre is straight faced as grid electricity is being used by the house (0.8kW in this example). We can see that eddi hasn't started heating with surplus power yet today as there is no accumulated energy; indicated by the 0.00kWh under the water cylinder symbol. eddi is now diverting power to the heater.
10. Manual Boost A heater can be ‘boosted’ to full power for a short period regardless of the amount of available export power, this function is called Manual Boost and is activated from the main screen. Once the boost starts, the remaining boost period will be displayed, this will start with a duration of 1 hour, this can be adjusted during the boost. The boost can be cancelled at any time. 10.1 Activating Manual Boost Step 1: From the main screen, press ().
11. Boost Timer eddi can be programmed to 'boost' the heating for each heater at certain times. Boost, means that the heater will be at full power regardless of the amount of available export power. This means that power may be drawn from the mains grid supply during boost times. There are four editable time slots for each heater. Setting the duration to 0h00 will make the boost inactive 11.1 Programming Boost Times Step 1: From the main screen, press (X) to enter the Main Menu.
11.2 Economy Tariff Boosting Boosting only when economy rate electricity is available can be achieved in one of three ways: 1. Setting the boost timer to coincide with the economy tariff times. This option should be used only if the electricity meter is a dual-rate meter (modern meters are usually multi-rate). 2. Boost only at set times AND if economy rate electricity is available* 3.
12.2 Priority The priority for heater outputs can be set to Heater 1 or Heater 2. The priority heater will be heated first with the surplus power and only when fully heated will eddi start to divert power to the lower priority heater. eddi will switch back to the priority heater if it has cooled and the thermostat for the heater is closed. When heating the lower priority heater, the Check Period sets how often the priority heater is checked to see if it can store any more heat.
13.1.4 Supply Grid – Battery If the property has a static AC battery system installed, it's possible to get the eddi to work in harmony with the system, provided a CT has been installed to monitor the battery inverter. See Battery Storage for more information about battery storage systems. Setting Function Description None There is no battery system installed Limit to Gen Will limit the output of the eddi (except when boosting), to prevent unwanted draining an of AC coupled battery system.
13.2 CT config The CT1 and CT2 inputs are configured depending on the connected CT sensors. The internal CT which measures the output current also has some settings. Note: These are the same when using CTs with the harvi device, however, they are set via the Linked Devices menu rather than the CT Config menu. IMPORTANT There must be only one Grid CT set (per phase) for the whole installation. CT CTINT Description This is the internal CT which measures the output current of the eddi. CT1 CT2 CT1 input.
13.2.1 CT Groups CTs can be put in groups so that their readings are netted. For example, you might want to monitor two solar PV systems and see the total generation on the display. Use Group in the CT Config menu to set which group the CT should be in. Note: Different CT Types cannot be in the same group, the group names make this clear. Only the first 4 groups can be used for current limiting, see Group Limits below. 13.2.2 Group Limits Current limits can be set for certain CT Groups.
14 Linked Devices Up to six myenergi devices can be wirelessly linked together. By linking devices, you can use more of your own energy or have more control and visibility. Devices available now are: A microgeneration energy diverter that uses surplus power to heat water or rooms rather than eddi exporting to the grid. zappi An eco-smart electric vehicle charge point that can use surplus power to charge the car.
14.4 Device Settings Most device types have settings which can only be changed via the Linked Devices menu. For example, eddi and zappi have a setting for priority and harvi has settings to configure its CT inputs. The device settings are accessed through the Linked Devices menu; select Devices then select the appropriate device and press (+) to bring up the device settings screen. Refer to the relevant device instruction document for more information regarding the actual device settings.
14.6 Linked Devices Information The current status of all linked devices can be viewed together in the LINKED DEVICES INFO screen which can be found from the Main Menu. 1. All linked devices are shown on the left. The current device is shown in CAPITAL letters. 2. The right side shows each device’s real-time output power level 3. The priority setting for each device is shown on the far left. 4. The far right side of the screen shows the status of each device.
