The Energizer Homepower HP-6 Series is an AC-coupled, lithium iron phosphate (LFP) based Battery Energy Storage System (BESS) designed for seamless integration with existing solar (PV) installations. It is a modular system, consisting of a Main Unit (HP-6M) and optional Sub Units (HP-6S), allowing for customization to suit various energy needs. The system intelligently measures solar generation and energy consumption using Current Transformers (CTs) and employs algorithms to charge or discharge batteries, aiming to reduce grid consumption and increase local energy usage, thereby improving overall energy efficiency and reducing export to the utility grid.
Function Description:
The HP-6 Series operates in three application modes: Automatic, Semi-Automatic, and Manual.
- Automatic Mode (Default): Prioritizes Site Loads > Battery Charge > Grid Export > Battery Discharge > Grid Import. Solar generation first supplies loads. Excess solar energy charges the battery. Once the battery is full (SoC 100%), excess solar is exported to the grid. If loads exceed solar generation (or at night), energy is discharged from the battery. If loads exceed both solar and battery output, the balance is drawn from the grid.
- Semi-Automatic Mode (Optional): Allows a percentage of solar generation to be reserved for battery charging and/or grid export. Priority: Site Loads > Battery Charge (& Grid Export) > Grid Export > Battery Discharge > Grid Import. Solar generation primarily supplies loads. Excess solar is divided between battery charging and grid export based on a user-defined percentage (e.g., 70% for PV Charge means 70% charges the battery, 30% is exported). If the battery is full, excess solar is exported. If loads exceed solar (or at night), energy is discharged from the battery. If loads exceed solar and battery output, the balance is drawn from the grid.
- Manual Mode (Optional): Enables electricity tariff arbitrage by customizing battery charge and discharge schedules. Batteries can be charged on-demand from solar or grid energy and discharged on-demand to site loads. The entire schedule is configured on the Energizer Homepower Cloud. This mode includes "Maximum State of Charge" to limit grid charging (e.g., to 80% SoC) and "Blank windows of time" where the system reverts to Automatic Mode if no instructions are entered.
The system is equipped with an integrated communications module supporting Wi-Fi, 4G/LTE, or Ethernet for internet connectivity to the Energizer Homepower Cloud, enabling real-time monitoring and remote troubleshooting. It also supports Demand Response Management (DRM) functions (DRMs 0-8) for compliance with utility regulations (AS4777 & AS4755 standards in Australia & NZ), controlling inverter power output via MODBUS commands.

Usage Features:
- Installation: Designed for both indoor and outdoor installations (IP65 rated). Requires installation on a wall capable of supporting its weight, with mandatory clearances for electrical cabling and airflow. Recommended locations include garages, ventilated storage areas, or dedicated battery rooms, away from direct sunlight, extreme rainfall, snow, flammable/corrosive equipment, and areas prone to flooding or high humidity.
- Connectivity: Supports Wi-Fi, 4G/LTE, and Ethernet for internet connection. An external antenna is supplied for Wi-Fi and 4G/LTE, which also serves as a hole blocker.
- Monitoring: The Energizer Homepower Installer App and web-based monitoring platform provide comprehensive monitoring and analysis. The system also features Edge Lighting to convey operating states (Normal, Stand-by, Fault) and an LCD panel (under the Magna-Flap) for real-time information on solar generation, energy consumption, backup loads, export, and battery SoC.
- UPS Function: The Main Unit (HP-6M) can supply power to essential loads (up to 3.6 kW/16 A) in the event of grid power loss.
