The primary function of a capacitor in an inverter is to manage and optimize the flow of electrical energy. Key roles include: Voltage regulation: Inverter capacitor assist in maintaining a consistent voltage level, preventing fluctuations that could potentially harm connected devices.
The choice ultimately hinges on the inverter's design, intended use, and performance demands. Ceramic dielectric capacitors are the most commonly used inverter capacitors because of their robustness, high capacity and fast response time.
Lots of people have thought of using capacitors on inverter DC input. It doesn't do any good because that's not how capacitors work. They don't produce power, they just 'borrow' it. There already are all the capacitors the inverter needs built in to the inverter.
There are of course no capacitors inside your inverter. Re: Has anyone thought of using capacitors between the inverter and battery? Would this There are of course no capacitors inside your inverter.

Yes, like car audio where the battery size and wiring is limited by other constraints. but in general it will be more expensive than just adding batteries. Having the right batteries and wires is cheaper and works better too. Re: Has anyone thought of using capacitors between the inverter and battery?
The inverter capacitor is mainly composed of multi-layer ceramic capacitor, coated paper dielectric capacitor, dielectric capacitor, ferroelectric negative capacitor and coil. Various types of capacitors find application in inverters, each catering to specific needs:
