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?
Capacitor is a simple two terminal device Terminals are metallic plates and there is a dielectric material (insulator) between them. Batteries provide energy to the connected circuits. i.e. Battery generates electrons and charge. Capacitors draw, store and release the energy. i.e. Capacitor only stores charged electrons.
Engineers choose to use a battery or capacitor based on the circuit they’re designing and what they want that item to do. They may even use a combination of batteries and capacitors. The devices are not totally interchangeable, however. Here’s why. Batteries come in many different sizes. Some of the tiniest power small devices like hearing aids.
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.
When a capacitor is connected to a battery, the charge is developed on each side of the capacitor. Also, there will be a flow of current in the circuit for some time, and then it decreases to zero. Where is energy stored in the capacitor? The energy is stored in the space that is available in the capacitor plates.
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed.
