EGbatt Hbrick-HV50A 400V DC High Voltage Battery Storage System – 16kWh LiFePO4
400V DC High Voltage Battery Storage
16kWh | 314Ah | LiFePO₄ | 330-450V Working Range
Most residential battery banks run at 48V. But modern high voltage hybrid inverters (Sol-Ark, Deye, GoodWe, Growatt) are designed for a 330-450V DC input. The EGbatt Hbrick-HV50A delivers exactly that – a true 400V DC system, not a boosted 48V afterthought.
Key advantages of 400V over 48V:
Lower current → less heat, higher efficiency (≥95% round-trip)
Thinner, cheaper cables → reduced installation cost
No transformer losses → direct DC coupling to inverter
Better scalability → up to 256kWh with 16 parallel units
400V DC High Voltage Battery Storage System – EGbatt Hbrick-HV50A 16kWh LiFePO4
EGbatt Hbrick-HV50A is a true 400V DC high voltage battery storage system designed for residential hybrid inverters that require 330–450V DC input. Unlike common 48V batteries, this 16kWh LiFePO4 battery delivers higher efficiency, lower current, and seamless communication with leading HV hybrid inverters.
Why Choose a 400V DC High Voltage Battery Over 48V?
Most home battery banks run at 48V, but modern high voltage hybrid inverters from SolArk, Deye, GoodWe, and Growatt are engineered for a 330-450V DC battery input. The EGbatt Hbrick-HV50A is a native 400V DC battery storage system, not a boosted 48V unit. This gives you:
- Higher efficiency – ≥95% round-trip, less heat loss
- Lower current – thinner cables, simpler installation
- Direct coupling – no external transformer or boost converter needed
- Better scalability – up to 256kWh with 16 parallel units
If you already own or plan to buy a high voltage hybrid inverter, pairing it with a 48V battery forces you to add expensive transformers or suffer efficiency loss. The Hbrick-HV50A eliminates that compromise.

Seamless Compatibility with High Voltage Hybrid Inverters
The Hbrick-HV50A communicates via CAN bus (2.0B) and RS485 (Modbus) – the two standard protocols used by virtually all high voltage hybrid inverters. It is tested and proven to work with:
- Sol-Ark (all HV series)
- Deye (SUN-*K-SG04LP3-EU series)
- GoodWe (EH, BH, HT series)
- Growatt (MIN, MOD, SPA series)
- Sungrow (SH series)
- Sofar, LuxPower, Victron Energy (with HV interface)
No additional gateway is required for most brands. Plug the supplied RJ45 cable into the inverter’s BMS port, select “Lithium Battery” mode, and the system auto‑negotiates.
Intelligent BMS – Safety, Monitoring & Balancing
The built-in Battery Management System (BMS) continuously monitors each cell and protects against:
- Over‑voltage (>57.9V on low side)
- Under‑voltage (<46.4V)
- Over‑current (>16A)
- Short circuit
- High temperature (>60°C)
- Low temperature (<0°C)
Active cell balancing keeps all 16 series cells within ±20mV, maximizing usable capacity over thousands of cycles. The BMS sends real‑time status (voltage, current, SOC, temperature) to your inverter via CAN or RS485.
Scalable – Parallel Up to 16 Units (256kWh Total)
Start with one 16kWh high voltage battery and expand as your energy needs grow. Up to 16 EGbatt Hbrick-HV50A units can be connected in parallel, achieving:
- Total energy: up to 256 kWh
- Total power: up to 80 kW (5 kW × 16)
- Automatic master‑slave configuration – no complex programming
Parallel installation tips: Ensure voltage difference between units is <1V before connecting. Use supplied LINK2/LINK3 daisy‑chain cables. After adding new units, perform one full charge cycle to balance SOC.

Shipping Notice
EGBATT has set a high standard for shipping lithium batteries. As lithium ion batteries fall under DG (dangerous goods) category, they use high-quality DG boxes or DG wooden cases to pack the batteries along with thick foam. This ensures that the batteries are delivered to customers in the best possible condition and without any damage.
We accept shipping
- By express or Air shipping like UPS, DHL, Fedex.
- Shipping by sea to port or to door service.
- FAC to Customer's forwarder company in China.
EGBATT ensures that all of its batteries meet the MSDS and UN38.3 standards. The packaging requirements for lithium batteries shipped by sea depend on the Watt-hour rating for lithium ion cells or batteries, or the lithium metal content for lithium metal cells or batteries. The packaging needs to meet UN specifications or be strong and rigid packing that can withstand the shocks, mechanical handling, and loading encountered during transport.
Shipping Regulation
If you are an international customer, please note that products will be shipped directly from China. To place your order, please contact odmbattery@outlook.com manually, rather than ordering on the website, as shipping costs may be inaccurate for regions outside of the USA.
EGbatt understands the importance of proper handling and regulation compliance when it comes to shipping lithium ion batteries. We take great care to follow all regulations for sea and air shipping to ensure the safe and secure transport of these potentially hazardous materials.
Shipping lithium ion batteries comes with specific guidelines outlined by transportation authorities, including the International Air Transport Association (IATA) and the International Maritime Dangerous Goods (IMDG) code, to minimize the risk of fire or explosion during shipping. These guidelines cover packaging, labeling, and documentation requirements, among other things. At EGbatt, we stay up-to-date with all current regulations and guidelines to ensure we are shipping our products safely and responsibly. We understand the risks involved with transporting lithium ion batteries and take the necessary precautions to minimize those risks for both our customers and our employees.
