As we mentioned earlier, there are multiple methods to disconnect
the inverter from the grid, but in the next section, we will focus on four common methods for RV inverter installation.
Four installation methods for disconnecting inverters from the power grid
1. Direct connection
Connecting your RV inverter directly to the AC distribution system of the RV through a conversion switch may be the most elegant and expensive solution for connecting inverters.
The conversion switch will automatically determine which power source to use;
For example, if shore power is available, the switch will select the shore
power inverter power if not.
If you choose to directly connect the inverter, you may want the inverter and converter to be turned on simultaneously to avoid the push-pull effect of energy.
Fortunately, you can avoid supplying power to these devices by using separate distribution boards.
Meanwhile, it is crucial to ensure that the type of switch used is based on your RV inverter and your generator (if any).
Now, if you think the direct connection method is more complicated, please read our following methods.
2. Use of relays
The use of relays is a simple and feasible method for connecting inverters.
Here, you only need to connect the extension cable from the inverter to any device you want to power.
Although this method can complete the work, you will soon realize that you will get tired of constantly inserting and removing extension cords from different devices.
Similarly, although simple, it often causes you to trip over extension cords.
3. Use of dedicated sockets
A slightly simpler option is to connect the inverter to one or more dedicated sockets.
Using this method, you can connect a new socket or disconnect an existing socket from the distribution box. Regardless of the method, the main challenge of this connection is determining the location of the socket and the difficulty of hard wiring.
One of the main drawbacks of this method is that it will mean that some sockets are not working, especially when using onshore power sources, which can be very frustrating.
4. Use a 30 ampere socket
This is another effective way to transmit power output from your inverter
This method requires the use of a 30 ampere socket installed outside the RV and then connected to the output of the inverter.
Now, when you want to power from the inverter, you need to plug the RV from the shore power source and then plug it into the socket.
However, as we mentioned earlier, when discussing direct connection methods, the inverter and converter should not be turned on simultaneously.
To overcome this stumbling block, it is necessary to first open the circuit breaker of the converter before turning on the inverter each time. Although practical, it is not feasible because you will definitely forget to pull the circuit breaker, which may cause damage.
A more practical solution here is to obtain a relay with a 120 VAC coil and a rated DC of at least 10 amperes, which will allow for safer practical operation.
In this way, when the inverter is turned on or off, the relay will automatically turn on or off the converter.
It is crucial to install the relay on or near the converter during this process. This
is because the current consumed by the relay coil can be ignored. If protection is needed, you can use light wires or cut off heavy-duty extension wires.
Now, you have four common RV installation methods. Regardless of the method you use, please ensure that your inverter is as close to the battery as possible to reduce voltage drop.
