FAQ
Q: What are the advantages of lead-acid battery energy storage systems compared to lithium battery energy storage?
A: The core advantages are reflected in three aspects: ① Lower cost: the initial investment cost is 30% to 40% lower than that of lithium battery energy storage, the raw materials are easily available, the production process is mature, and it is suitable for large-scale low-cost energy storage scenarios; ② Higher reliability: The technology has been validated in the market for decades, with strong resistance to impact, overcharge and over discharge, and a lower failure rate under extreme working conditions; ③ Simplified operation and maintenance: no water replenishment, no maintenance required, no need for a professional team to be on duty, and the later operation and maintenance costs are significantly lower than those of lithium batteries; ④ Higher safety: no risk of thermal runaway, sealed design with no leakage or explosion hazards, and more controllable operation.
Q: How to choose the appropriate energy storage capacity and voltage level based on demand?
A: The selection criteria are as follows: ① Energy storage capacity: determined based on load power, backup time, or new energy generation (capacity=load power x backup time ÷ charging and discharging efficiency, if a 10kW load requires 10 hours of backup, it is recommended to choose a 120kWh capacity); ② Voltage level: 380V AC is preferred for grid connected scenarios, adapted to the voltage of the power grid; Off grid emergency scenarios can choose 48V/110V/220V AC to match the load voltage requirements. We can provide accurate selection solutions for free based on your load parameters and usage scenarios.
Q: Does the lead-acid battery energy storage system need regular maintenance? How is daily operation and maintenance carried out?
A: This product uses valve regulated lead-acid batteries, and its core advantage is maintenance free, without the need for regular water and acid replenishment. Daily operation and maintenance only need to do three things: ① Regular inspection: check the shell for damage and loose wiring every month to ensure good heat dissipation and ventilation; ② Environmental control: Avoid long-term storage/operation in environments below -30 ℃ or above 60 ℃, and take sun and rain protection measures for outdoor installation; ③ Remote monitoring: Real time monitoring of battery operation status through BMS backend, timely handling of fault warnings. Under normal circumstances, there is no need for a professional operation and maintenance team, which can significantly reduce operation and maintenance costs.
