Product Description

Working Logic

In general, the transfer switch allows switching between the grid, an inverter, and a generator/ alternator as power sources. The grid power remains available (pass-through) when using the transfer switch. When grid power is available, the transfer switch automatically connects to the control panel terminals. If operating with an onboard vehicle alternators, starting the alternator triggers a 20 to 30-second delay before power transfers from grid power to the alternator, allowing the alternator voltage to stabilize. Once the alternator stops, the transfer switch immediately and automatically reconnects to grid power.

Switching Between the Grid and an Inverter

When both the grid and an inverter are connected to the transfer switch, the switch will prioritize grid power to supply loads. In the event of a grid power failure, the inverter will automatically take over and supply power to the loads.

Switching Between the Grid, a Generator/an Alternator, and an Inverter

The transfer switch enables seamless switching between the grid, a generator/an alternator, and an inverter when two transfer switches are installed in a system. The first transfer switch connects the grid and a generator/an alternator as two AC power sources, while the second transfer switch links the first transfer switch to the inverter. The system prioritizes grid power supply. When grid power is insufficient, the generator/alternator is selected as the power source. If the generator/alternator shuts down, the inverter supplies power.

FAQ

Q: How to Choose the Right 30A Transfer Switch?

A: Make sure to select a transfer switch that is appropriate for the current load of your system. Check the maximum current requirements of the device you will be connecting and ensure that the transfer switch is rated at 30A. Also, verify that the input voltage range supported by the switch is compatible with your system.

Q: Do You Need a Professional Electrician to Purchase and Install It?

A: Yes. The 30A transfer switch involves electrical connections and must be installed in accordance with local electrical safety codes and standards. It is recommended that qualified electricians install the device to ensure safety and compliance. Before installation, check the power and current ratings of all connected devices to avoid exceeding the maximum load.

Q: How to Install the 30A Transfer Switch Correctly?

A: Disconnect the power supply during installation and follow the wiring diagram in the product manual. Ensure that the input and output ports are properly connected and that the cables are securely fastened. For reserved wiring holes, use cables or conduits of appropriate size. During installation, electricians should consider the switch’s placement to avoid exposure to humidity or high-temperature environments.

NOTE: Relay and ground bar cables are supported in the 6–14 AWG range.

Q: What Can I Do if the Device Fails?

A: Immediately turn off the transfer switch and disconnect the power supply. If sparks or smoke are observed, it may be due to poor wiring, overload, or internal failure. Do not attempt to repair it yourself—be sure to contact a professional electrician for inspection and repair.
