• Long Lifespan:​ Designed for over 6,000 cycles. With one cycle per day, it can last more than 10 years while maintaining 80% capacity, significantly outperforming standard storage products .

• Smart Management:​ The built-in smart BMS allows real-time monitoring and APP remote control. It supports time-of-use electricity pricing modes, automatically charging during off-peak hours and discharging during peak hours to maximize electricity bill savings .

Product Parameters

Application Case

Case: A Residential PV Storage Project in Tianjin

A household in Tianjin's Binhai New Area installed a 5kW rooftop solar system paired with a Liwei 10kWh storage battery. Over one year, the system generates approximately 20kWh daily. The storage battery stores excess solar energy during the day for use at night, saving about ¥3,000 annually. During summer peak periods, an additional ¥200 per month is saved through peak/off-peak arbitrage. The system also provides backup power during grid outages, ensuring basic household electricity needs are met .

Q&A

Q1: What are the installation requirements for the home storage battery?

A: Installation requires: 1) A well-ventilated location away from direct sunlight; 2) Adequate wall or floor load-bearing capacity (wall-mounted units weigh 30-50kg); 3) Ambient temperature between -20°C and 55°C; 4) A compatible professional inverter from recommended brands .

Q2: What daily maintenance is required?

A: Routine maintenance includes: 1) Regular visual checks for bulging or deformation; 2) Keeping vents clean and dust-free monthly; 3) Avoiding deep discharge; recommended SOC between 20%-80%; 4) For long-term storage, charge to 50%-60% SOC and recharge every 3 months .

Q3: What is the warranty policy?

A: Tianjin Liwei offers a 5-year warranty. If capacity degrades beyond 20% within the warranty period, free replacement is provided. A 48-hour on-site repair service is available, covering remote areas. The company also offers recycling services for old batteries .
