3. Introduction
3.1 Basic features
The ESC-hybrid inverter can store the energy in the battery for self-use and also can convert the
DC current of the PV generator into AC current for on grid or off grid usage.
ESC-hybrid inverter with EPS can supply the energy from battery and PV generator when the
grid is lost.
The below diagram are for reference based on different local wiring rules.
Diagram A : Neutral line of alternative supply must not be isolated or switched. applies to the
wiring rules that requires Neutral line of alternative supply must NOT be isolated or switched
(applies to wiring rules AS/NZS_3000:2012 for Australia and New Zealand).
Diagram B: Neutral line of alternative supply can be isolated or switched. applies to the wiring
rules that requires the Live line and Neutral line of EPS must be disconnected with the Live line
and Neutral line of grid. (applies to most countires)

3.2 Work modes
The ESC-Hybrid inverter has below working modes for your home made energy storage system.
Work modes: Self-use (With PV Power)
Priority: load>battery>grid
This mode applies the area that has low feed-in tariff and high energy price.
The power generated from PV will be used to supply the local loads firstly, then to charge
the battery. The redundant power will export to the pubic grid.
1) Generated solar energy
2) Load consumption
3) Storage in Battery
4) Feed the remaining solar energy
into the grid

8
Work modes: Self-use (Without PV Power)
When no PV supplied, battery will discharge for local loads firstly, and. grid will supply power
when the battery capacity is not enough.
Work modes: Force time use
Priority: battery>load>grid (when charging)
Priority: load>battery>grid (when discharging)
1) Battery discharge for load
2) Grid supply power when the battery
capacity is not enough
3) Load consumption
1) Generated solar energy
2) Storage in battery
3) Load consumption
4) Grid supply power when the
battery capacity is not
enough

9
This mode applies the area that has electricity price between peak and valley. User can use
off-peak electricity to change the battery. The charging and discharging time can be set
flexibly, and it also allows choosing whether charge from the grid or not.
Work modes: Back up mode
Priority: battery>load>grid
This mode applies the area that has frequent power outages. And this mode ensures the
battery will has enough energy to supply when the grid is off.
In this mode battery will be charging forcibly in the setting time and will never be discharged
when the grid is on, and it also allows to choose whether charge from the grid or not.
Work modes: FFR Use mode
FFR (Firm Frequency Response) is a service provided by energy users to National Grid,
which uses approved assets to quickly reduce demand or increase generation to help
balance the grid and avoid power outages.
National Grid needs help when there are large deviations in system frequency caused by too
much generation compared to demand or vice versa e.g. when a power station unexpectedly
shuts down. In such events, to ensure that generation and demand can be quickly balanced
1) Generated solar energy
2) Storage in Battery
3) Load consumption
4) Grid supply power
1) Generated solar energy
2) Load consumption
3) Self-use from battery
4) Grid supply power when the
battery capacity is not enough

10
to avoid blackouts, FFR uses approved assets to quickly reduce demand or increase
generation.
FFR function decription:
