❓ Frequently Asked Questions
Q
What are the key technical differences between the 261KWh and 520KWh energy storage systems?
The main differences lie in battery capacity, dimensions, and cooling methods. The 261KWh model has a rated capacity of 314Ah, uses air cooling for the battery, and weighs about 2600kg. The 520KWh model has a rated capacity of 628Ah, utilizes liquid cooling, and weighs approximately 4900kg.
Q
How does the liquid cooling system work in the energy storage system?
The 520KWh model uses a full liquid cooling method that maintains a strict temperature difference of ≤3ºC. This guarantees optimal performance, enhances system safety, and extends the overall battery lifespan.
Q
Is this energy storage solution compatible with solar installations?
Yes, the systems support PV input with maximum PV power of up to 120KW for the 261KWh version and 240KW for the 520KWh version. They operate with an MPPT voltage range of 250-950Vdc.
Q
What is the transition time when switching from on-grid to off-grid mode?
The system features a rapid grid switching time of less than 10 milliseconds, ensuring continuous power supply for critical commercial and industrial loads.
Q
What standard certifications do your products comply with?
Our systems are certified according to global requirements, including ISO 9001, ISO 14001, ISO 18001, TUV, CE, ROHS, IEC, PID, DEWA, CB, RETIE, INMETRO, Ammonia 62716, and Salt Mist Corrosion 61710 standards.
