My gate opener was connect to a 240V power outlet on the wall through a AC 240V to AC 16V transformer. The gate opener has a 12V battery inside. This is specification of the gate opener: Motor: 120 Watt 12v DC Transformer: 16v AC 1 Amp Battery change voltage: 13.8v DC

Few weeks ago, the 240v power outlet on the wall was broken and cannot provide power anymore. It is the only 240 power outlet near by the gate and very difficult to replace the cable because it is placed under ground.

One work around soultion I planed is to connect a converter (Input AC 240V, Output DC 12V,2.8A) to another 240V power outlet in the house, then extend the 12V power out put through a heavy duty garden electrical cable to the gate. Then, connect the cable to a DC 12V to AC 240V (1000W) inverter. Then connect the inverter's output to the gate opener's transformer (AC 240V 24W to AC 16V 1A).

It looks working for me, but will this cause higher electricity cost as the inverter will run at all the time. Is this a feasible solution? any damage to the gate opener??

  • \$\begingroup\$ 240v to 16v transformer is fixed connect to the opener. If use DC12V to AC16V, have to cut off the connection of the trnasformer. \$\endgroup\$

  • \$\begingroup\$ I do think you should depict something, as I don't quite understand. \$\endgroup\$ Nov 7, 2021 at 23:19
  • \$\begingroup\$ Is this a feasible solution? it is unknown ... the problem is unclear ... as @MarkoBuršič says, please provide a diagram of the gate system \$\endgroup\$
