FAQ
1.How is the early warning of the safety system realized?
BMS three levels, the first level of warning, the second level of alarm to reduce power, three levels of power outages; there are temperature sensors, smoke sensors, combustible gas detection, the use of propane fire extinguishing, there are remote and on-site alarms, far infrared video surveillance and video recording and other ways.
2.How is ultra-high voltage converted to supply voltage?
Inside the enterprise, through the substation or transformer, the ultra-high voltage of the utility will be converted into the supply voltage, which will supply the normal equipment use and the energy storage setup use.
3.Warranty issue, cycle count issue, how many times is the normal battery cycle count?
Warranty 5 years before three years free of charge, after two years of charging accessories fees, travel costs battery's normal cycle life of more than 6,000 times a day, 1 charge and 1 discharge, can be used for more than 15 years, 2 charging and 2 discharging can be used for more than 8 years.
4.How to maximize the efficiency of 2 charging 2 discharging?
Valley-peak, flat-peak (full charging and discharging) so that the system utilization rate is maximum.
5.What are the configuration facilities of the energy storage cabinet?
By the battery battery management system BMS energy storage converter PCS energy management system EMS, fire system, monitoring system and other related auxiliary systems, small size, large storage capacity, high temperature and low temperature resistance.
6.What are the benefits of energy storage cabinets?
(1)Shaving peaks and filling valleys, saving more than 60% of electricity costs by utilizing the peak and valley price difference. (2) Not subject to power outages, blackouts and power restrictions, not affecting normal production. (3) State subsidized equipment to offset corporate income tax. (4) Emergency disaster preparedness standby. (5) reduce carbon emissions, grid-connected operation, all gains, data open and transparent national grid monitoring and accounting (6) iron phosphate battery will not trigger its own thermal runaway, no explosion or fire.
7.How much floor space do energy storage cabinets really need?
100kwh-215kwh indoor energy storage cabinet installation footprint in 4m weight of about 25T three-sided side-by-side design covers a small area. Outdoor cabinets are designed in accordance with fire protection and temperature control requirements and can be placed in the open space outside the power distribution room.
8.What is the annual maintenance cost of the energy storage cabinet?
About every 1 MWh maintenance fee of about 10,000, the first 3 ~ 5 years maintenance costs less maintenance costs after five years of maintenance costs of about a full set of equipment costs of 0.5-2%; (investment in 1WKH of the energy storage cabinet investment costs of about RMB 1.45 million yuan after five years of maintenance costs of about RMB 7,000 yuan ~ 28,000 depending on the degree of aging on the site between)
