System Components

Lithium Battery Cluster

The main components of system consist of a battery module formed by safe, high-efficiency, long-life lithium iron phosphate cells connected in series, and a battery cluster formed by multiple modules connected in series.

Battery Management System

The core component of the svstem effectivelv protects the battery from over-charging, over-discharging, over-current, etc., and at the same time manages the equalization of the battery cells to guarantee the safe, reliable and efficient operation of the whole system.

Monitoring System

System operation data monitoring, operation strategy management, historical data logging, system status logging, etc.

PCS Power Conversion System

Bidirectional AC/DC converter can realize the bidirectional conversion of DC to AC and AC to DC, which can either convert AC to DC for charging the battery, or convert DC to AC to supply power to the load or feed back to the grid.

Air Conditioning System

The battery compartment integrates 1200W industrial air conditioner to meet the smooth operation of the svstem in different environments and prolong the service life of the system.

1P54

IP54 design for the whole system.

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.

Annual maintenance fee for the storage locker?

Roughly, for every 1 MWh, the maintenance fee is about 10,000 yuan, the maintenance fee is less in the first 3 to 5 years, and the maintenance fee after five years is about 0.5-2% of the cost of the whole set of equipment; (investing in a 1 WKH energy storage cabinet, the investment cost is about 1,450,000 yuan, and the maintenance fee after five years is about 7,000 yuan to 28,000 yuan, depending on the degree of aging on the site)
