Cheaply made but works

I’m using this for a little different application. Instead of switching to a battery back up, I’m switching off of batteries to an AC/DC converter. My son-in-law is using solar power to run a 24vdc pump for his hydroponics system, but if he has no sun for a few days, the batteries don’t get charged enough. I set this up to switch power to an AC/DC converter when the battery level gets too low to keep the pump running. It’ll switch back when the batteries get a sufficient charge. Essentially, I am using the Shelly relay and MQTT to do the switching. Do note, as others have mentioned, there is a delay of about a half a second in switching between the two sources. This is not a problem with the pump. It may be for more sensitive electronics.

Great product that did exactly what we wanted. I ran 12v from our vehicle that is the primary power to our RV but it pulls from the battery when disconnected. Only 4 stars as it is just a circuit board and you have to have a housing that protects it which is a bit bizarre.

Diesel Heaters do not like this switch as the delay in switching over to battery backup is to long, Causing unit to shut off and smoke out. This switch would work on something that isnt so fragile to voltage disruption.
