Product Description

Battery module
Using Lifepo4 cells from leading brands such as EVE and REPT, with a single pack capacity of 16.07kWh and a total capacity of 980kWh / 1200kWh, and the cycle life over 8000 cycles.
PCS (Power Conversion System)
It enables bidirectional conversion between DC power from the battery and AC power from the grid/load. Simultaneously, it stabilizes voltage and frequency, regulates charging and discharging power, and receives commands from the BMS to ensure safe and stable system operation.
EMS (Energy Management System)
Overall scheduling of all equipment, including batteries, PCS, and distribution cabinets. It intelligently controls charging and discharging strategies based on grid demand, electricity prices, or load conditions, monitors operational status in real time, uploads data, and enables system safety protection, energy consumption optimization, and remote scheduling.

Bidirectional Energy Conversion: Achieves bidirectional conversion between DC and AC power via PCS, enabling charging and energy storage during periods of low electricity prices or surplus photovoltaic power, and discharging to supply power during peak demand or grid failures.
Photovoltaic Synergistic Optimization: Works in conjunction with the photovoltaic system to smooth out fluctuations in photovoltaic output, store excess photovoltaic energy, and improve the utilization rate of renewable energy.
Backup Power Guarantee: Provides uninterrupted power to critical loads through rapid switching in the event of grid or diesel generator (DG) failures via STS static transfer switch.
