1. The parameters set in the host cannot be changed at will during use. In particular, the parameters of the battery pack will directly affect the service life. With the change of ambient temperature, the float charge voltage should be adjusted accordingly. Generally 25°C is the norm, and the floating charge voltage should increase by 18mV for every 1°C increase or decrease in ambient temperature.
2. When the UPS power supply system is self-supplied, it should be prevented from starting the UPS power supply with load, turn off each load first, and then turn on the load after the UPS power supply system starts. When the load is supplied instantaneously, there will be an impact on the battery, and the inrush current of multiple loads and the required power supply current will constitute an instantaneous overload of the UPS power supply.
3. In the case of floating charging operation, it is still in the charging and discharging maintenance, and it is necessary to ensure that the voltage and current meet the regulations. Too high voltage or current may cause thermal runaway of the battery, and too little voltage and current will cause battery power loss, which will affect the service life of the battery.
Fourth, the UPS power supply system should prevent arbitrarily increasing the rated equipment of high power in the application, and it is not allowed to operate for a long time under full load. The nature of the operation determines that the UPS power supply system operates in an uninterrupted state, which increases the high-power load, and will damage the converter when it is severe.
Fifth, the battery needs to prevent high-current charging and discharging. Although it can withstand large currents during charging, it should be prevented as much as possible in actual operation, otherwise it will cause the battery plate to swell and deform, so that the active material of the plate will fall, the internal resistance of the battery will increase, the higher the temperature rise, and the more severe the capacity will decrease.
6. The battery should be prevented from short circuit or deep discharge. The cycle life of a battery is related to the depth of discharge. The deeper the depth of discharge, the shorter the cycle life. In the capacity test or discharge maintenance, the discharge can reach 30%-50% of the capacity. Schneider UPS power supply system has a high degree of intelligence, and the energy storage battery adopts a protection-free battery. Although it brings a lot of convenience to the application, it is necessary to pay attention to the application process to ensure the safety of the operation.

The difference between an inverter and a servo drive – Schneider
In terms of frequency converters:
The abbreviated inverter can only regulate the speed of the communication motor, and the open-loop or closed-loop can be determined depending on the control method and the inverter, which is the traditional V/F control method. Now many of the frequency conversion has been set up by mathematical models, which will communicate electricity ...
