Why doesn't the inverter support lithium batteries?

The voltage is unstable. The voltage variation range of lithium batteries is relatively wide. The voltage is generally between 3.0V and 4.2V during charging, but the voltage may be lower than 3.0V during discharging, which may have an adverse effect on the stability of the inverter. The inverter must operate at a higher voltage level. If the voltage fluctuation of the lithium battery is unstable, it will easily cause the inverter to have unstable current fluctuations, which will affect the normal operation of the inverter and even cause damage to the inverter. . The inverter therefore does not support lithium batteries.
