Smart Panel

In 2017, as Switchgear specialists, Twyver executed a Smart Panel project with a new client. Having presented the Smart Panel at the Smart Factory Expo (NEC, Birmingham) last November 2016 for the first time, this is the first order of the Twyver Smart Panel allowing remote control/notifications via a Smartphone.


The project will entail the supply of a generator and the addition of an auto-changeover section to an existing Switchboard, the changeover section will be complete with outgoing supplies and automatic control.


One of the client major criteria is the special requirement of automatic text message response to allow the client to monitor the status of the generator (e.g. when the Generator is called to start and when the system returns to mains and the Generator stops). Being aware of the status of the board at all times will allow the client to monitor fuel use and maintenance requirements on the generator.
