Tutum Energy Compact Installation CVO63 & CVO100
The Compact single-phase voltage optimisation system from Tutum Energy is designed for use in residential properties and small commercial buildings. The 63 Amp unit is easily fitted by a competent electrical installer and simply requires two wires in and two wires out to make it fully operational. A process that only takes around one hour.
Another attractive feature of the Tutum Energy Compact domestic voltage optimisation system is that, unlike smart meters, it does not require a complete change in behaviour and unlike solar and wind power it is not focused on renewable energy production, but rather on reducing energy consumption all day every day
Single-phase Installation
Tutum Energy Compact requires a 230V (nominal) single-phase supply, which is fed from the incoming mains to the home. The supply to the Tutum Energy system must be fitted with suitably rated protection and isolation to allow maintenance (if required) and to conform to current regulations and standards.
