FAQ

FAQ

1.Q: What working modes does your energy storage system support, and can it be connected to a photovoltaic system?
A: It supports three working modes: off-grid, grid-connected and hybrid power supply. It can seamlessly connect to photovoltaic inverters to realize self-consumption, surplus power storage and grid power supply, maximizing the utilization of clean energy.

2.Q: What is the cycle life of the battery of the energy storage system, and how long is the warranty period?
A: It uses lithium iron phosphate battery cells with a cycle life of ≥6000 times (remaining capacity ≥80%). The battery pack provides a 5-year warranty, the entire system provides a 2-year warranty, and lifelong maintenance is supported.

3.Q: What core protection functions does the BMS of the energy storage system have?
A: The BMS has overcharge, overdischarge, overtemperature, overcurrent, short-circuit and cell balancing protection functions, which real-time monitor the battery status to ensure the safe and stable operation of the system and avoid potential safety hazards.

4.Q: What conditions are required for the installation and commissioning of the energy storage system, and does your company provide technical support?
A: A flat and ventilated installation site (indoor/outdoor) and access to voltage lines that meet specifications are required. Our company provides complete installation drawings and operation manuals, supports remote commissioning, and can also arrange engineers to provide on-site guidance (fees are negotiable separately).

5.Q: What is the energy efficiency level of the energy storage system, and what should be paid attention to in daily operation and maintenance?
A: The comprehensive charge-discharge efficiency of the system is ≥95%, reaching the leading energy efficiency level in the industry. For daily operation and maintenance, it is necessary to regularly check the battery temperature, clean the heat dissipation vents, avoid heavy object extrusion or exposure to the sun, and non-professionals are not allowed to disassemble the equipment.
