The 80kW–125kW / 210kWh All-in-One BESS is an integrated commercial and industrial energy storage solution combining a Solis hybrid inverter, 210kWh LiFePO₄ battery system, BMS, and intelligent energy management in a compact and easy-to-deploy design.
The system intelligently coordinates energy flow between PV, grid, battery, and loads, enabling efficient solar energy utilization, battery charging and discharging, peak shaving, load shifting, and backup power. During normal operation, excess solar energy can be stored in the battery for later use, while during grid outages, the stored energy can provide reliable backup power for critical loads.

2. Hybrid Inverter – 100–125kW
The integrated 100–125kW hybrid inverter manages power flow between the PV system, battery, grid, and loads. It supports battery charging/discharging, solar energy utilization, peak shaving, and backup power operation.
3. Control Box
The control box provides centralized system control and communication, coordinating the battery, inverter, BMS and other components for stable and intelligent operation.
4. Air Conditioning
The integrated air-conditioning system maintains a suitable internal temperature for the battery and electrical components, helping improve battery performance, safety, and service life, particularly in outdoor or high-temperature environments.
5. Smoke Alarm / Fire Safety
The cabinet is equipped with a smoke detection system for early detection of abnormal conditions, enhancing the overall safety of the energy storage system.
The 80–125kW Solis Hybrid Inverter serves as the central energy management unit, coordinating power flow between the PV system, grid, battery, and loads. Combined with a 210kWh LiFePO₄ battery system, it provides an integrated solution for energy optimization and backup power.
PV Power Generation
Solar energy is first supplied to the loads. Excess PV power can be used to charge the 210kWh battery, maximizing solar energy utilization.
Battery Energy Storage
The 210kWh battery stores surplus solar energy and releases it when required, such as during peak-demand periods or grid outages.
Grid Interaction
The Solis hybrid inverter can manage energy exchange with the grid according to the system configuration, supporting self-consumption, peak shaving, load shifting, and backup power.
Backup Power
When the grid fails, the hybrid inverter automatically switches the designated loads to battery power, maintaining power supply to critical equipment. The actual transfer time depends on the inverter and system configuration.
Flexible Power Configuration
The inverter can be configured within the 80–125kW power range, while the 210kWh battery provides sufficient energy capacity for extended backup and daily energy management.
F&A = FAQ（Frequently Asked Questions）
Q1: What is the capacity of this energy storage system?
A: The system is equipped with a 210kWh LiFePO₄ battery and an 80–125kW Solis hybrid inverter, providing both energy storage and intelligent power management.
Q2: What is the main function of the Solis hybrid inverter?
A: The Solis hybrid inverter manages energy flow between the PV system, grid, battery, and loads, enabling solar self-consumption, battery charging/discharging, peak shaving, and backup power.
Q3: How long can the 210kWh battery provide backup power?
A: The backup duration depends on the actual load. For example, at a 100kW load, the theoretical backup time is approximately 2.1 hours. Actual runtime depends on battery SOC, system efficiency, and operating conditions.
Q4: Can the system work when the grid fails?
A: Yes. The hybrid inverter can switch to battery backup mode and supply power to designated loads during a grid outage, subject to the system configuration and backup-load capacity.
Q5: Can the battery be charged by solar panels?
A: Yes. Excess solar energy can be used to charge the battery, allowing the stored energy to be used later when solar generation is insufficient.
