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. This setting does not require a CT to monitor the
battery, but does need a CT to monitor the solar/wind generation.
Note:
This setting is to support legacy installations – it is preferable to install a CT to
monitor the battery and use one of the settings below.
Avoid Drain
Stops the
eddi
(or other linked
myenergi
devices) draining the battery when using
surplus power from the solar or wind generator.
Avoid Charge
Effectively allows the
eddi
(or other linked
myenergi
devices) to take priority over the
battery when charging from solar or wind generation.
Avoid Both
Provides both of the above functions.
13.1.5
Supply Grid – Net Phases
When enabled, all readings from 3-phase
myenergi
devices and
harvi
units configured as 3-phase, will be
netted. This means that surplus generation on ANY phase will be considered to be available for consumption
on ANY other phase.
13.1.6
Supply Grid – Exp Threshold
This is the amount of export that must be exceeded before
eddi
starts diverting power to the heater loads.
Once diverting starts all the surplus power, less the Export Margin (see below) will be diverted to the heater
load.
13.1.7
Supply Grid – Response Delay
This setting gives 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-side battery storage system installed at the
property, this may need to be increased. For example, the storage system will be trying to charge the batteries
with the surplus power, but because
eddi
is very fast, the surplus power would have already been consumed
by
eddi
. This may be undesirable as it would usually make more economic sense to store the energy in the
batteries as priority.
13.1.8
Supply Grid – Export Margin
This sets a minimum level of export power which is maintained when
eddi
is diverting surplus power to the
heaters. Normally Export Margin would be set to 0W (zero watts) and all of the available surplus will be diverted
to the heaters, however, it is sometimes desired to have a minimum export level at all times.
