Emergency Power Supply (EPS) - Method 1: Connecting a Socket
To connect the EPS port to a socket, you can use a regular double socket. Normally, the EPS socket gets power from the electricity grid through the inverter. But if there's a power cut, you can use solar panels and/or batteries to power the socket.
Depending on the type of inverter you have, you might need to add a relay to create a neutral earth bond. For safety, it's important to attach an earth spike (called TT Earthing) to the socket. This helps with electrical grounding and keeps things safe in the event of a fault. Make sure to check the EPS port's amp capacity. Some inverters only supply 13 amps, so be careful not to overload the port. Overloading it could cause the inverter to shut down and possibly get damaged.
👍Advantages:
