Myenergi Eddi+ Manual

Introduction

eddi+ is a 3-phase energy regulator, with manual/automatic action for use with microgeneration systems. Excess energy from the microgeneration system is used to heat water or rooms rather than exporting it to the grid. Grid current sensors simply clip around the incoming cables. These sensors are used to monitor excess power so eddi+ can automatically adjust the voltage to connected heater. eddi+ can effectively balance excess power across all three phases. eddi+ utilises myenergi's proprietary varisine™ technology to ensure compliance with worldwide power grid standards.

Installation

1. Remove eddi+ from packaging.
   
2. Place device on a flat surface, loosen the pozi-head captive screw (1) and lift cover off in a tilting motion.
   
3. Loosen the two mounting bracket screws (2) and separate the bracket from the eddi+.
   
4. Place the bracket against the wall of the chosen location and mark the holes ready for drilling and fixing.
   Suitable fixings must be used dependant on application/mounting surface. To be determined by the installer.
5. Pierce holes in grommets and pass all cables through and terminate to the corresponding terminals relative to the installation.

ELECTRIC SHOCK - An electric shock can be fatal; electrical connection work shall only be carried out by a competent person.

Supply
Supply cable shall meet the requirements of the local wiring regulations.
Strip 8mm insulation from conductors and insert into the terminals. The eddi+ should be connected to a 3-phase 230/400V AC 50Hz supply.

Loads
Only purely resistive loads shall be used with eddi+. The following criteria shall be observed:

• Maximum rating of load: 3kW per phase
• Minimum load rating: 150W
• The load's neutral conductor shall be connected to the load output N terminal
• No electronic controls shall be connected to the load terminals; mechanical thermostats only
• No timers shall be connected to the load terminals, including mechanical timers

Ethernet
If applicable, ensure Ethernet is inserted into the RJ45 port.

6. Fit CT(s) to live conductors as necessary, with arrow marked in direction of current flow.
   
   Only one Grid CT (per phase) for the whole installation. Extending CT To extend the CT sensor cable, a single pair from a CAT5 cable may be used.
   Extending CT
   To extend the CT sensor cable, a single pair from a CAT5 cable may be used.
   

7. Clamp all cables, using the cable clamps provided.
   
8. Refit the eddi+ cover and tighten the pozi-head screw (1) to secure.
   
9. Carry out all relevant tests and inspections in accordance with local regulations, before applying power.
10. Once powered up, follow through the installation assistant set-up screens to configure the device settings. This will include setting a passcode to the Installer Settings Menu.

Installer Settings

Phase Rotation
Phase Rotation is only used on three phase devices and should correspond to the wiring of the input terminals. Only the following specific options are available:

• 1/2/3 (Ph-1 to "L1", Ph-2 to "L2", Ph-3 to "L3")
• 2/3/1 (Ph-2 to "L1", Ph-3 to "L2", Ph-1 to "L3")
• 3/1/2 (Ph-3 to "L1", Ph-1 to "L2", Ph-2 to "L3")

Device Limit
The maximum current that eddi+ will draw per phase (including when boosting). This is useful if the supply current is limited.

Grid Limit /Import Limit
The limit that can be drawn from the grid connection i.e. maximum import current or the main property fuse rating. This is a global limit so all paired myenergi devices will be included when limiting.

Third Party AC Battery
If the property has a static AC-coupled battery system installed, it's possible to get the eddi+ to operate as shown in the following table, provided a CT has been installed to monitor the battery inverter.

Net Phases
All meter readings from 3-phase myenergi devices will be netted. This means that surplus generation on ANY phase will be considered to be available for consumption on ANY other phase. T his will allow eddi+ to monitor the total grid export and import figures. You will need to net the three phases. To do this, in the eddi+ device menu, navigate to; Supply Grid > Net Phases and enable net phasing.

Exp Threshold
The amount of export that must be exceeded before eddi+ starts diverting power to the connected load. Once diverting starts, all the surplus power less the Export Margin (see below) will be diverted to the connected load.

Export Margin
Sets a minimum level of export power which is maintained when eddi+ is diverting surplus power to the heater. Normally Export Margin would be set to 0W (zero watts) and all available surplus will be diverted to the load, however, it is sometimes desired to have a minimum export level at all times.

Response Delay
Sets a delay before eddi+ starts to divert power (after the Export Threshold is exceeded). The default setting is 0s (zero seconds), however, if there is an AC-coupled battery storage system installed at the property, this may need to be increased.

Load Balancing/Current Limiting
CTs can also be used to limit the current drawn by myenergi devices to avoid overloading circuits; this is referred to as load balancing or load curtailment. There are four different ways to limit current and they can be used alone or combined for more complex situations.

Relays and eSense
eddi+ relays and eSense options allow for numerous wiring configurations and includes the following features:

• Two independent relays rated at 250V AC, 16A.
• eSense input (Range 3.3-230Vrms. Volt Free Contact; 24V DC Supplied from the zappi).
• Two temperatures sensor inputs (PT1000)

The two relays can be independently set for several functions, or they can be set to operate as a pair.
The relay functions include:

• Export Threshold
• Import Threshold
• Operate when heating
• De-stratification pump control
• Timed operation
