．What is an inverter?
Inverter is an electrical device that converting direct current (DC) to alternating current (AC), the resulting AC (AC) may at any required voltage and frequency with the use of appropriate transformers, switching and control circuits. Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries.

．If the inverter which contains a charger, then can I use the power inverter and charger (PIC) the function ofinvert and charge both at the same time?
No. If the inverter has a charging function, it the switching from the charger to the inverter can be manually controlled orautomatically controlled. In both controlling modes, you cannot operate the charger and the inverter at the same time.
