China Solar Energy Storage System Manufacturers Suppliers Factory - Customized Service

Commercial & Residential LiFePO4 Energy Storage Systems

Direct-Factory OEM/ODM Solutions for Solar Distributors & EPC Contractors

Our energy storage systems store excess solar electricity for peak-load shifting, self-consumption optimization, and automated backup power during grid failures. Built around lithium iron phosphate (LiFePO4) cells, an integrated modular Battery Management System (BMS), and standard communication protocols, our units integrate directly into new or existing residential and commercial solar installations. Successfully deployed in over 50 MWh of commercial and residential projects across Europe, Southeast Asia, and the Americas, our hardware is field-proven for reliability.

Technical Highlights & Specifications

LiFePO4 Cell Chemistry:

Utilizes stable lithium iron phosphate chemistry designed to resist thermal runaway, supporting a wide operational temperature range of -20C to 55C without active liquid cooling in standard environments.

Lifecycle & Degradation:

Rated for 6,000 to 8,000 cycles at 80% Depth of Discharge (DoD) under nominal conditions (25C), yielding a standard operational lifespan of 10 to 15 years.

Hardware-Level BMS:

Each module tracks individual cell voltages, pack current, and board temperatures in real-time. It actively executes hardware protections against over-voltage, under-voltage, short-circuits, and cell imbalance.

Inverter Compatibility:

Ships with native support for CAN 2.0, RS485, and Modbus RTU, ensuring physical and protocol-level compatibility with major hybrid inverter brands (e.g., Deye, GoodWe, Growatt, Victron).

Modular Scalability:

Enclosures and rack-mount units support parallel expansion from 5 kWh to over 500 kWh without requiring master control replacements.

Performance Comparison

Feature	Technical Implementation	Operational Benefit
Round-Trip Efficiency	Inverter-to-battery loop efficiency up to 95%	Minimizes thermal energy loss during charge/discharge cycles.
Enclosure Rating	IP54 indoor standard; IP65 outdoor optional	Protects internal components against dust ingress and water spray.
Installation Profile	Stackable floor-mounted cabinets or wall brackets	Reduces on-site mechanical installation time for technicians.
Firmware Integration	Local LCD display, local app via Bluetooth, and remote cloud portal	Simplifies post-installation troubleshooting and diagnostics.

OEM & Customization Capabilities

As a direct manufacturing facility, we offer full-spectrum private-label production tailored to regional certification and branding requirements:

Electrical Customization:

Voltage scaling (e.g., 48V low-voltage stacks or 200V-800V high-voltage HV systems).

Enclosure Branding:

Silk-screened logos, custom sheet-metal color powder-coating, and tailored front-bezel design.

Software Localization:

Custom communication protocol mapping for proprietary inverter firmware, localized touch-screen UI, and branded cloud monitoring apps.

Regulatory Compliance:

Documentation packages provided for CE, UN38.3, RoHS, and MSDS. Target-market specific certifications (IEC 62619, UL 1973) can be arranged based on project volume.

FAQ

Q: What is the typical lead time for bulk orders?

A: Standard configurations ship within 15 to 25 days. Custom OEM housing or specialized firmware integrations require 30 to 45 days for sample approval and tooling setup.

Q: Can these batteries be added to existing solar setups?

A: Yes, provided the existing inverter is a hybrid or off-grid model with support for external battery banks via CAN or RS485 communication protocols.

Q: What maintenance is required during operation?

A: No routine maintenance or fluid replenishment is required. Periodic checks involve inspecting terminal torque connections, cleaning air intake filters (for forced-air models), and checking firmware log files via the monitoring platform.
