3U High Voltage Rack Battery

I. Core Advantages

1. Standard 3U/19-inch rack, high-voltage platform

3U height, 19-inch standard cabinet size, directly installed without cabinet modification, extremely compatible with the data center/cabinet.

High-voltage DC (HV) design: system voltage can reach 200~500V+, compatible with mainstream high-voltage PCS/inverters, lower line loss, higher efficiency, and better cost.

2. High energy density + modular flexible expansion

Single module typically 5–6kWh (51.2V/100Ah level), 3–12 units connected in series to form a high-voltage cluster, capacity ranging from 15kWh to 60+kWh as needed for expansion.

Support for multiple parallel connections, industrial/commercial / energy storage stations can expand from tens of kWh to several MWh smoothly, without wasting the initial investment.

3. Grade A lithium iron phosphate, ultra-long cycle + wide temperature operation

Using LiFePO4 Grade A battery cells, cycle life ≥ 6000 times @ 80% DOD, lifespan 10 years +.

Ultra-wide temperature range: charging - 10℃~60℃, discharging - 30℃~60℃, stable operation in high humidity 5%–95%, suitable for high/low temperature / outdoor data centers.

4. Intelligent BMS + multiple safety protections

Built-in industrial-grade intelligent BMS: overcharge / overdischarge / overcurrent / short circuit / overtemperature / balancing full protection, active + passive balancing, good cell consistency.

RS485/CAN/RS232 multiple communication ports, support remote monitoring, data collection, alarms, can be connected to the customer's cloud platform.

Metallic reinforcement, insulation strengthening, IP protection + air switch dual protection, safer operation.

5. Easy installation, easy transportation, easy maintenance

Rack-mounted + front/back maintenance, front panel operation, no need to move the cabinet; modular design, each module weighs approximately 35–45kg, 2 people can quickly install.

Friendly for ocean transportation: standard box size, stable stacking, no on-site welding / wiring, ready for installation upon arrival.

6. High cost-effectiveness, compatible with mainstream inverters / PCS

Has entered the white list of many leading inverters / PCS (such as Deye, SMA, Goodwe, etc.), ready to use, highly compatible.

High-voltage architecture reduces copper bars / cables / losses, lower system BOS cost, for traders: good profit margin, fewer after-sales services, low repair rate.

II. Application Scenarios

1. Communication base stations / data center backup power

5G base stations, data centers, IDU/ODU, edge computing sites: replace lead-acid batteries, long lifespan, small footprint, less maintenance.

2. Industrial and commercial energy storage (C&I ESS)

Factories, shopping malls, office buildings, parks: peak-valley arbitrage, demand management, backup power, off-grid / grid-connected.

3. Household / villa high-voltage energy storage (main force in Europe / overseas households)

Combined with high-voltage inverters: self-power supply, photovoltaic energy storage, emergency backup, grid-connected / off-grid.

4. Off-grid / microgrid (photovoltaic + energy storage integration)

Islands, mining areas, pastures, remote villages: photovoltaic + 3U high-voltage battery + PCS form off-grid power stations.

5. UPS backup power + medical / precision equipment

Hospitals, laboratories, precision manufacturing: high-voltage UPS, long delay, high reliability.

6. Container energy storage / large-scale energy storage station (front-end unit)

Stack 3U racks in containers to form high-voltage energy storage clusters, standardized, easy replication, quick delivery.

III. Solution Capability

1. Full-stack high-voltage energy storage solution design

Can be customized according to customer needs: voltage level (200–500V), capacity (15kWh–MWh level), cabinet configuration, BMS communication protocol. 1. Provide system diagrams, wiring diagrams, layout diagrams, construction instructions. Traders/contractors can directly use them.

2. Multi-brand PCS / inverter deep compatibility

Compatible with mainstream high-voltage inverters, providing test reports + whitelist support. Customers can achieve successful on-site debugging in one go.

3. Standard + non-standard rapid customization

Standard 3U models are in regular stock, with fast delivery time; special voltage / capacity / communication can be quickly customized within 2-4 weeks.

4. Global certifications + compliant delivery

Full series of CE, RoHS, UN38.3, MSDS, IEC62619 certifications are complete. Export is worry-free, customs clearance is smooth.

5. Localized technical support + after-sales guarantee

Provide English materials, overseas installation videos, remote debugging; key markets can support local warehouses + local after-sales services.

Warranty: 5-year standard warranty, can be upgraded to 10 years, reducing customer risks.
