22kW 32kWh solar UPS case study-11kW solar inverters and 16kWh LiFePO4 battery project analysis

With the rapid development of renewable energy, solar energy storage systems have become an essential solution for households and businesses to improve energy self-sufficiency and reduce electricity costs. This case study showcases a high-efficiency energy storage system consisting of two MOTOMA 11kW inverters and two M90 PRO 16kWh energy storage batteries, providing stable power supply for residential and small commercial applications.

System Configuration Overview

• Inverters: 2 MOTOMA 11kW inverters
• Energy Storage Batteries: 2 M90 PRO 16kWh lithium batteries
• Total Storage Capacity: 32kWh
• Maximum Inverter Power: 22kW

Solar Panel Configuration Estimation

To maximize the efficiency of the energy storage system, we recommend installing sufficient solar panels for effective charging. Assuming each solar panel has a power output of 550W and an average daily effective sunlight duration of 5 hours, the calculation is as follows:

Required Solar Panel Power = (Total Battery Storage / Sunlight Hours) + Inverter Load

Solar Panel Power ≈ (32kWh / 5h) + 22kW = 6.4kW + 22kW = 28.4kW

Required Solar Panel Quantity = 28.4kW / 0.55kW ≈ 52 panels

Therefore, this system is recommended to be equipped with 52 x 550W solar panels to ensure daily charging needs and load supply.

Load Support Capability

With a maximum output power of 22kW, this system can support the following common loads:

• Household Applications: Central air conditioning (5kW), refrigerator (0.5kW), lighting (0.3kW), washing machine (1kW), TV (0.2kW), induction cooker (2kW), totaling approximately 9kW, which can be sustained for over 3.5 hours.
• Commercial Applications: Small office space with computers (20 units × 0.2kW), printers (2 units × 1kW), lighting (1kW), air conditioning (5kW), totaling about 10kW, which can be supported for about 3 hours.

Key Advantages

• Long Cycle Life: The M90 PRO battery supports 8000+ cycles, with a lifespan of over 10 years.
• Smart Monitoring: Supports remote monitoring and allows battery status tracking via an app for efficient management.
• High Efficiency and Safety: Equipped with an intelligent BMS system, providing multiple protections against overcharging, over-discharging, and short circuits.
• Scalability: Supports up to 15 battery packs in parallel, making it suitable for larger energy storage demands.

Conclusion

The energy storage system in this case study is ideal for users who require a stable, reliable, and scalable energy solution. It not only reduces electricity costs but also serves as a backup power source during outages. Whether for residential, commercial, or industrial applications, this system offers an efficient, intelligent, and secure green energy experience.
