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 the loads.
e. When site loads are greater than the sum of solar generation and battery output, the balance is drawn from
the utility grid.
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 export to utility grid. E.g., if PV Charge % is set to 70%, then 70% of solar generation is used to charge
the battery, and 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.
