An indoor photovoltaic energy cabinet is a compact, integrated energy storage system designed to be deployed inside telecom facilities. It combines lithium battery storage, PV input, and intelligent management to ensure stable power and optimize energy usage.
Key benefits include:
Highjoule uses high-safety LFP (LiFePO₄) cells—typically 3.2V/90Ah or 280Ah modules—combined with intelligent BMS and EMS to ensure reliable indoor operation, long lifecycle, and safe charge/discharge behavior.
The cabinet accepts direct PV input via MPPT controllers, storing excess solar energy for later use. The EMS prioritizes “solar-first” logic, ensuring that daytime solar generation supports the base station load before drawing from the grid.
Yes. The cabinet includes a fast-response backup system. When the grid fails, it instantly switches to battery mode, ensuring zero-disruption to base station operations. It’s ideal for areas with frequent blackouts or poor grid quality.
Typical indoor cabinets are designed with a small footprint (e.g., 600mm × 1000mm), allowing installation in base station rooms, IDF/MDF areas, or under-rack spaces. The modular design supports scalable energy capacity from 5kWh to 30kWh or more.
Yes. It comes with a built-in intelligent control platform (EMS/BMS) that supports remote access, fault alarms, real-time SOC monitoring, load profiles, and integration with telecom network operation centers (NOCs).
Highjoule’s indoor photovoltaic energy cabinets comply with telecom industry standards and pass certifications such as CE, UL1973 (battery), IEC62619, and local fire-safety and EMC requirements, ensuring safe deployment in telecom environments.
Yes. It supports hybrid inputs—solar + grid + battery—and can be integrated with generator backups when needed. The EMS optimizes energy flow based on power quality, time-of-use pricing, and energy availability.
The system is designed for low-maintenance operation with periodic inspections. The battery modules are sealed and fan-cooled (or optional liquid cooling), and software diagnostics reduce the need for manual interventions.
