HinaESS Hi-5 5.12kWh 51.2V Lithium Iron Phosphate Battery
The HinaESS Hi-5 is a 5.12kWh low-voltage lithium energy storage battery designed for residential and light commercial solar systems where reliability, scalability, and inverter compatibility are critical. Built using lithium iron phosphate (LiFePO₄) cells, the Hi-5 delivers stable performance, strong safety characteristics, and long service life under daily cycling conditions.
This battery is designed for 48V-class systems and integrates directly with a wide range of hybrid and inverter-charger platforms via CAN or RS485 communication.
Intended System Role and Applications
The Hi-5 battery is designed to store energy generated from solar PV systems and make it available during grid outages, load shedding, or peak demand periods. Typical applications include residential solar backup systems, hybrid inverter installations, small businesses, and modular energy storage systems requiring reliable daily cycling.
It is not a high-voltage battery and is not intended for commercial or industrial HV inverter platforms.
51.2V Low-Voltage Battery Architecture
Operating at a rated voltage of 51.2V, the HinaESS Hi-5 falls within the standard low-voltage lithium battery class used by most residential hybrid inverters. This voltage range offers a balance between safety, efficiency, and ease of installation while allowing meaningful power output when paired with correctly sized inverters.
LiFePO₄ Cell Chemistry and Performance
The battery uses LiFePO₄ cells, known for their thermal stability, resistance to thermal runaway, and consistent voltage delivery. The Hi-5 supports a 1C continuous charge and discharge rate, allowing up to 100A of continuous current, making it suitable for systems that require both backup power and daily solar cycling.
Peak discharge capability reaches 105A for 15 seconds and 120A for 0.5 seconds, supporting short-term surge loads.
Smart BMS and Active Cell Balancing
An integrated smart Battery Management System continuously monitors voltage, current, temperature, and state of charge. The system includes active balancing to improve long-term cell consistency and reduce degradation.
Multiple protection functions are built in, including over-charge, over-discharge, over-current, over-voltage, over-temperature, short-circuit protection, reverse connection protection, and low-SOC protection.
Parallel Scalability and System Expansion
The Hi-5 battery supports parallel connection of up to 32 units without the need for additional external devices. Batteries can be added or removed without affecting system operation, allowing flexible system expansion over time.
This makes the Hi-5 suitable for modular energy storage systems that grow as energy requirements increase.
Inverter Compatibility and Communication
The battery communicates via CAN and RS485 and is compatible with a wide range of inverter brands including Victron, Luxpower, Deye, Voltronic, SMA, Goodwe, Growatt, Sofar, Sol-Ark, SRNE, and Must.
Proper inverter selection and configuration are essential to ensure correct communication and battery protection.
Installation Environment and Physical Design
The Hi-5 features a compact sheet-metal enclosure with an IP20 protection rating, intended for indoor installation in dry, ventilated environments. The battery is suitable for wall-mounted or rack-based installations depending on system design.
