PV & Battery Energy Management System

This system integrates photovoltaic (PV) generation input, lithium iron phosphate (LiFePO4) battery storage, and bi-directional inverter control into a single architecture. It regulates power dispatch between solar arrays, energy storage units, local loads, and the utility grid. Manufactured in a 20,000+ m2 production facility with an annual battery pack capacity of 1 GWh, the unit is engineered for commercial, industrial, and residential microgrids requiring automated load shifting, peak shaving, and uninterrupted backup power.

Cell Sorting & Consistency: Automated cell grading machines sort lithium-ion cells by capacity and internal resistance prior to assembly, minimizing cell imbalance during deep-cycle operations.

Structural Integration: Enclosures utilize heavy-gauge sheet metal with weatherproof gasket sealing, protecting internal components against moisture and dust ingress in outdoor installations.

BMS Architecture: Multi-tier Battery Management System (BMS) continuously monitors individual cell voltages, pack temperature, and current throughput to prevent overcharging, deep discharge, and thermal runaways.

Thermal Regulation: Air-cooled and liquid-cooled configurations maintain uniform cell temperatures, mitigating degradation across high-ambient-temperature deployments.

Core Subsystems: PV combiner interface, bi-directional power conversion system (PCS), LFP battery rack, BMS master/slave controllers, and central Energy Management System (EMS) HMI.

Electrical Layout: Pre-wired internal busbars, integrated DC/AC circuit breakers, surge protection devices (SPD), and emergency hardware trip loops.

Mechanical Build: Modular rack-mount battery modules combined with a floor-standing or wall-mounted master control cabinet, utilizing automated laser welding for internal current collectors.

Commercial & Industrial (C&I) Peak Shaving: Discharges stored energy during peak utility tariff windows to suppress maximum demand charges.

Commercial Load Shifting: Stores low-cost grid or excess solar energy during off-peak hours and utilizes it during high-rate periods.

Telecom Backup Power: Provides stable DC/AC microgrid support for remote cellular towers prone to unstable local grid infrastructure.

Off-Grid Microgrids: Acts as the primary frequency and voltage regulation source for isolated rural communities or remote industrial sites.

Inverter Integration: Compatible with standard high-voltage and low-voltage hybrid inverters through open-protocol CAN/RS485 communication.

SCADA & EMS Interoperability: Supports Modbus TCP/IP protocols for integration into third-party plant controllers and energy management software.

Retrofit Capabilities: Can be coupled with existing solar PV installations via AC-coupling topologies without rewiring existing generation arrays.

OEM/ODM Engineering: Custom enclosure dimensions, custom paint finishes, and tailored BMS firmware logic available for volume procurement.

Capacity Scalability: Modular rack designs allow parallel expansion of battery banks up to MWh-scale deployments.

Logistics & Packaging: UN38.3 certified packaging compliant with hazardous material shipping regulations for ocean and land freight.

In-House Verification Lines: Every production batch undergoes automated optical inspection (AOI), laser weld integrity checks on automated assembly lines, and high/low-temperature environmental chamber testing.

Cyclic Performance Validation: Automated battery cycle testing systems execute continuous charge-discharge profiling to verify capacity retention before final packaging.

Quality Frameworks: Production operations strictly conform to ISO9001 quality management mandates and ISO14001 environmental safety protocols.
