There are two main types of inverters: pure sine wave and modified sine wave. Pure sine wave inverters produce power similar to your home electricity. They are ideal for sensitive electronics. Modified sine wave inverters are cheaper. But, they may not work well with all devices.
Power Requirements
Determine your power needs before choosing an inverter. List all the appliances you plan to use in your RV. Check their wattage ratings. Add up the total wattage. Choose an inverter that meets or exceeds this total. Consider future power needs too.
Preparing The Rv For Installation
Preparing the RV for installation is a crucial step when wiring an inverter to the breaker box. Proper preparation ensures safety and efficiency. Follow these steps to make sure your installation goes smoothly and correctly.
Shutting Off Power
First, shut off all power sources in the RV. Disconnect the RV from any external power supply. Turn off all breakers inside the RV. This prevents electrical accidents during the installation process.
Inspecting The Breaker Box
Next, inspect the breaker box. Open the box and check for any signs of wear or damage. Ensure all connections are secure and there are no loose wires. Identify the breakers you will connect to the inverter. Make a note of their positions and ratings. This will help in the wiring process.
Mounting The Inverter
Mounting the inverter in your RV is a crucial step. This ensures it operates safely and efficiently. Follow these simple steps to secure the inverter properly. Let’s dive into the details.
Selecting A Location
Choose a location that is dry and well-ventilated. The inverter needs enough air to cool down. Avoid placing it near heat sources or in damp areas.
Ensure the spot is easy to access. This helps with maintenance. It is best to mount the inverter close to the RV breaker box. This reduces the length of the wiring, minimizing power loss.
Securing The Inverter
Once you have the location, it is time to secure the inverter. Use the mounting brackets provided by the manufacturer. These ensure a firm hold.
Follow these steps:
- Mark the spots where you will drill holes.
- Drill the holes carefully.
- Align the inverter with the holes.
- Screw the mounting brackets into place.
Make sure the inverter is level. This prevents it from moving or vibrating when the RV is in motion. Double-check all screws to ensure they are tight.
