In the NetCol5000-A air conditioner, if a large number of air bubbles are observed in the liquid crystal mirror, it indicates that the refrigerant system lacks refrigerant, and the refrigerant should be charged as needed.
To balance the capacity loss caused by the self-discharge of the battery during the use of the battery, it is necessary to charge the battery continuously and for a long time at constant voltage, which is called ().
During the use of the battery pack, the appearance is normal, but there is no current during charging, and the voltage drop is zero at the moment of discharge, and it cannot be discharged. What could be happened in the following?
When four UPS2000G-20K parallel units are set and the number of redundant units in the parallel setting is set to "1", the capacity of the system is () KVA.
