2. Semi-Automatic Mode - is an optional mode. The system allows for a certain percentage of the solar
generation to be reserved towards battery charging and/or export to grid. The system determines the energy
supply requirement with the priority: Site Loads > Battery Charge (& Grid Export) > Grid Export > Battery
Discharge > Grid Import. The operating sequence is as follows:
a. Solar generation is mainly utilised to supply the connected loads.
b. When site loads are lower than solar generation, excess solar energy is divided between battery charging
and/or export to utility grid. E.g. if PV Charge % is set to 70%, then 70% of solar generation is used to
charge the battery, whereas the remaining 30% is exported to the utility grid.
c. When site loads are lower than solar generation and battery is full (SoC 100%), the excess solar generation
is exported to the utility grid.
d. When site loads are greater than solar generation (or at night time), energy is primarily discharged from
the battery to supply these loads.
e. When the site loads are greater than both solar generation and/or battery discharge combined, the
balance is drawn from the utility grid.
3. Manual Mode - is also an optional mode. The system allows for electricity tariff arbitrage by customising
battery charge and discharge functions. The battery can be charged on-demand using either solar or utility
grid energy and can be discharged on-demand towards site loads. The entire schedule can be configured on
Energizer Homepower Cloud.
3.1. Maximum State of Charge - This setting is found on the Application
Mode window within customer app/portal. It limits the maximum
SOC capacity that the grid can charge the battery to. E.g. If set to
80%, then the grid can be used to charge until SOC hits 80%. Above
this SOC level, the grid will not be used to charge the battery.
3.2. Blank windows of time - When there are no instructions for the
Scheduler entered for a window of time then the unit will revert to
Automatic Mode until it reaches a window of time with instructions.
a. Automatic mode logic:
Site Loads > Battery Charge > Grid Export > Battery Discharge >
Grid Import.
3.3. Percentages - Within the Scheduler, you will need to input a
percentage for the instruction you want the Plant to follow.
a. This value is the percentage of the maximum inverter
capacity (3600W). E.g. For grid charge, if you input 60% then
only 2160W (~60% of 3600W) will be used to charge the battery
from the grid.

3.4. Grid Charge - Specifies when to use the grid to charge the battery. If left unticked, Energizer Homepower
will not charge from the grid.
a. E.g. 20% @ 5am - 7am - Following this instruction, the battery will charge from the grid at 720W
between the times of 5am and 7am.
When used: Designate when to charge the battery, normally during off peak periods.
This allows customers to reduce the need to consume grid power during peak periods.
3.5. PV Charge - Limits the amount of solar generation used to charge the battery (e.g. 50% @ 10am - 12pm).
a. E.g. 50% @ 10am - 12pm - With these instructions, during 5pm - 9pm, only 2160W will be available
for use from the battery. If any additional power is required, it will be drawn from the grid.
When used: Generally used to exempt scheduled periods of time from using the battery
or ensure availability of battery power by minimising consumption throughout the day.
E.g. When heat pumps are scheduled to be on during off peak periods.
3.6. Discharge to loads - Restricts how much energy is drawn from the battery during times when site loads
are greater than solar generation. Usually, early mornings and in the evenings.
a. E.g. 60% @ 5pm - 9pm - With these instructions, during 5pm - 9pm, only 2160W will be available for
use from the battery. If any additional power is required, it will be drawn from the grid.
When used: Generally used to exempt scheduled periods of time from using the battery
or ensure availability of battery power by minimising consumption throughout the day.
E.g. When heat pumps are scheduled to be on during off peak periods.
