FAQ
How is the early warning of the security system realized?
BMS three levels, a first level of warning, the second level of alarm power reduction, three levels of power outages; temperature, smoke, combustible gas detection, the use of propane fire extinguishing, there are remote and on-site alarms, far infrared video monitoring and recording and other ways.
How is ultra-high voltage converted to supply voltage?
Inside the enterprise, the ultra-high voltage of the utility power is converted into supply voltage by means of a substation or transformer to supply normal equipment use and energy storage setups.
Warranty issues, cycle count issues, how many cycles is a normal battery?
Warranty 5 years, the first three years free of charge, the next two years to charge the cost of accessories, travel costs; the normal cycle life of the battery in 6000
The normal cycle life of the battery is more than 6000 times, 1 charging and 1 discharging per day can be used for more than 15 years, 2 charging and 2 discharging can be used for more than 8 years.
How do you maximize the efficiency of 2 charging and 2 discharging?
Valley-peak, flat-peak (full charge and discharge) This maximizes system utilization.
What are the configuration facilities of the storage cabinets?
It consists of battery pack, battery management system BMS, energy storage converter PCS, energy management system EMS, fire protection system, monitoring system and other related auxiliary systems.
system, monitoring system and other related auxiliary systems, small size, large storage capacity, high temperature and low temperature resistance.
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 troubled by power outages, pulling the power limit, not affecting normal production.
(3) State subsidies, equipment credit for corporate income tax.
(4) Emergency disaster preparedness standby.
(5) Reduce carbon emissions, grid-connected operation, all benefits, data open and transparent, national grid monitoring and accounting.
(6) Lithium iron phosphate battery will not trigger its own thermal runaway, no explosion, no fire.
How big of a footprint do you really need for an energy storage locker, how big is 20 feet how big is 40 feet?
(1) The size of 20-foot container is: 6.058*2.438*2591 meters; 40-foot container size is:
12.192*2.438*2591 meters (1.5-2 meters position is reserved around the box for maintenance).
