CTS Modular 5kWh 10kWh 15kWh 48V LiFePO4 Battery Stackable Solar Storage with BMS for Home/Off-grid System

The global shift toward renewable energy and sustainable living is accelerating the adoption of solar power systems for residential and commercial applications. Homeowners and businesses are increasingly turning to solar energy to reduce electricity costs, achieve energy independence, and contribute to a cleaner environment. At the heart of every efficient solar system lies a reliable, high-performance battery storage solution that ensures power availability day and night.

Today, a growing number of energy storage applications — including solar self-consumption, home backup, off-grid systems, UPS, and telecom base stations — are transitioning to cleaner, safer, and more efficient lithium battery power. As lead-acid batteries are gradually phased out due to limited usable capacity (only 50-70% available without damage) and short cycle life, LiFePO4 batteries are emerging as the ideal replacement, offering nearly 100% usable capacity and 4,000+ charge-discharge cycles.

With advanced engineering and strong OEM capabilities, CTS Battery provides customized lithium battery solutions tailored to the specific energy and space requirements of each application.

Our solutions are designed to deliver:

• Reliable backup power for home and commercial use
• High energy density with reduced weight and footprint
• Safe operation in a wide temperature range
• Seamless integration with solar inverters and hybrid systems
• Whether you are installing a new solar system or upgrading an existing battery bank, CTS helps you build a safe, high-performance, and future-ready energy storage system.

Our LiFePO4 batteries are engineered with IP65 waterproof and dustproof housing, steel enclosure, and vibration-resistant construction to withstand various installation environments. With over 4,000 cycles at 80% depth of discharge, they deliver dependable performance for years to come.

Up to 50% lighter than traditional lead-acid batteries, significantly reducing installation effort and space requirements. The modular design saves valuable space and allows for flexible placement. The compact footprint makes it ideal for both wall-mounted and floor-standing installations in homes, garages, or utility rooms.

Built-in intelligent Battery Management System ensures:

• Overcharge / over-discharge protection
• Cell balancing and temperature control
• Short circuit and overcurrent protection
• Real-time SOC / SOH monitoring via CAN / RS485 / RS232

We understand that every solar system has unique power requirements. That's why we offer:

• Capacity options: 100Ah / 200Ah / 300Ah
• Voltage: 51.2V nominal (48V system)
• Parallel connection for expanded capacity
• CAN / RS485 / RS232 communication protocols
• IP65 / higher IP ratings upon request
• Size and structure tailored to installation space

Unlike other lithium chemistries, LiFePO4 offers superior thermal stability, non-toxic materials, and zero risk of thermal runaway, making it the safest choice for residential and commercial energy storage. The chemistry is inherently stable even under extreme conditions, ensuring peace of mind for homeowners.

With a maximum charging current of 100A and round-trip efficiency exceeding 95%, our batteries minimize energy loss during charge-discharge cycles, maximizing the utilization of solar energy and reducing electricity bills.
