5.12kWh rack-mount LiFePO4 battery, 8000 cycles for solar backup & off-grid power

This rack-mount energy storage battery from SUNPOK ENERGY is built as a high-performance alternative to traditional lead-acid and low-grade lithium batteries for residential and light commercial energy systems. Adopting a standard 19-inch rack-mount structural design with a rugged metal housing, it can be easily integrated into standard server racks, achieving orderly wiring and space-saving installation in garages, equipment rooms and basements.

At the technical level, the battery uses grade-A lithium iron phosphate cells with stable chemical properties, which fundamentally avoids safety risks such as thermal runaway and combustion. The built-in advanced Battery Management System (BMS) realizes full-link monitoring and protection of the battery pack, and supports RS232, RS485 and CAN communication protocols to achieve seamless docking with mainstream hybrid inverters on the market.

With a modular parallel design, the battery supports flexible capacity expansion of up to 15 units. Users can configure the number of batteries according to their own power consumption and solar system scale, which can meet the needs of daily solar self-consumption, household power outage backup, off-grid power supply and other scenarios, with high long-term investment return.

faq

Q1: What inverters are compatible with this 51.2V 100Ah LiFePO4 battery?

A: This rack-mounted battery supports standard RS232, RS485 and CAN communication protocols, making it widely compatible with most mainstream hybrid solar inverters on the market (including Deye, Growatt, Solis, GoodWe, Sungrow and more). It supports real-time data communication and coordinated control with the inverter for stable system operation.

Q2: How many battery modules can I connect in parallel? Can I expand capacity later?

A: You can connect up to 15 identical 51.2V 100Ah battery modules in parallel, scaling total energy storage from 5.12kWh up to 76.8kWh. The modular design allows you to start with a single unit and add more modules as your energy needs grow, without replacing your existing system.

Q3: What is the actual service life of the battery? What warranty does it come with?

A: Under normal operating conditions (25℃ ambient temperature, 95% depth of discharge), the battery delivers 8000+ charge-discharge cycles while retaining 80% of its original capacity, with a 30-year design service life. SUNPOK ENERGY provides a standard product warranty and professional after-sales technical support for all our energy storage batteries.

Q4: Can this battery be installed outdoors?

A: No. This rack-mounted LiFePO4 battery has an IP20 protection rating and is designed for indoor use only. It should be installed in a dry, ventilated, temperature-controlled environment such as a garage, utility room, basement or equipment closet, away from direct sunlight, rain and corrosive environments.

Q5: Does this LiFePO4 battery require regular maintenance?

A: No. Unlike lead-acid batteries, lithium iron phosphate batteries are maintenance-free. The built-in intelligent BMS automatically performs cell balancing, voltage monitoring and safety protection. You only need to perform simple visual inspections periodically to keep the casing clean and ensure terminal connections are tight.

Q6: What are the charge and discharge voltage parameters of this battery?

A: The standard float charge voltage is 58.4V, and the discharge cut-off voltage is 43.2V. The built-in BMS will automatically control the charge and discharge process within the safe voltage range to prevent overcharge and over-discharge damage.

Q7: What are the dimensions and weight? Does it fit a standard server rack?

A: The battery measures 480mm (L) × 440mm (W) × 150mm (H) and weighs 45kg. It adopts a standard rack-mount design and is fully compatible with standard 19-inch server racks, making installation neat and space-saving.

Q8: Will deep discharging damage the battery?

A: This LiFePO4 battery is designed for deep cycle use. It supports 95% depth of discharge (DOD) in daily use and can maintain 8000+ cycles under 95% DOD. The built-in BMS also provides over-discharge protection, so normal deep discharge use within the rated range will not damage the battery.

Q9: What precautions should I take for transportation and installation?

A: The battery should be transported and stored in an upright position, avoiding heavy impact and inversion. Installation must be performed by a qualified professional electrician. Please ensure proper grounding, correct positive and negative terminal connections, and disconnect power before any wiring operation.

Q10: What advantages does this LiFePO4 battery have over traditional lead-acid batteries?

A: Compared with lead-acid batteries, SUNPOK LiFePO4 rack batteries have 4-6 times longer cycle life, higher depth of discharge (95% vs 50-60% for lead-acid), higher energy density, zero maintenance requirements, better high-temperature stability, and no risk of acid leakage or toxic gas emission, making them safer and more cost-effective in the long run.
