5 kilowatt-hours, 10 kilowatt-hours, 15 kilowatt-hours, and 20 kilowatt-hours.

Here’s the English translation:

Application Scenarios:

• 5kWh: Suitable for small households or low-power demand scenarios, supporting lighting and small appliances.

• 10kWh: Fits medium households for daily electricity use, powering common appliances like air conditioners and refrigerators.

• 15kWh & 20kWh: Ideal for large households or spaces with multiple appliances, ensuring long-term operation of high-power devices.

Green and Environmentally Friendly
Powered by solar energy, it emits zero CO₂, sulfides, or other pollutants, helping reduce greenhouse gas emissions and aligning with global green development principles.

High Efficiency and Energy Saving
With high charge-discharge efficiency (up to ~95% in some models), it effectively reduces energy conversion and storage losses, enhancing overall energy utilization.

Economical and Durable

• Long Cycle Life: Over 6,000 cycles, minimizing replacement costs.

• Cost Savings: Use self-generated solar power during the day, sell excess power to the grid for subsidies or bill credits. In time-of-use pricing areas, charge during low-rate periods and discharge during peak rates to save on electricity bills.

Safe and Reliable
Lithium iron phosphate (LFP) batteries feature strong thermal stability, resisting thermal runaway at high temperatures and maintaining stability during collisions or punctures, thus reducing fire and explosion risks.

Intelligent Management
Built-in Battery Management System (BMS) continuously monitors parameters like voltage, current, temperature, and charge level. It optimizes charging/discharging automatically and provides multiple protections against overcharge, over-discharge, overheating, and short circuits.

Flexible and Scalable
Modular design supports stacking or parallel connection of multiple battery units, allowing flexible capacity expansion as needed. Easy to install and maintain for future upgrades.
