Solar Inverter Printed Circuit Boards

- Resistors. Convert electrical energy into thermal energy.
- Transistors. Control the output current with a small input signal.
- Capacitors. Store electrical charge and release it when needed, helping to regulate power.
- Inductors. Store energy in the form of a magnetic field, blocking unwanted signals or interference.
- Transformers. Transfer electrical energy from one circuit to another, regulating voltage levels.
- Diodes. Allow electric current to flow in one direction.
- Sensors. Detect changes in the environment and generate electrical signals in response.
- Solid-state switches. Convert direct current to alternating current.

The choice of material for solar inverter circuit boards is critical to their performance and durability:

- FR-4 is a flame-retardant plastic laminate. It has mechanical strength, wide temperature range and high glass transition temperature.
- PTFE (polytetrafluoroethylene) - known for its electrical insulating properties, low dielectric constant and high thermal stability. It is resistant to moisture, chemicals and extreme temperatures.
- Teflon - provides low signal loss.
- Polyimide - heat resistant material.
