Domestic Voltage Optimisation (DVO) is an energy-saving technology used to reduce the voltage supplied to electrical equipment to the optimal level for efficient operation. often with the aim of saving energy, extending appliance life, and lowering electricity bills. Here's a breakdown of what it involves:
Most electrical grids supply voltage at levels higher than needed—typically 230V to 250V, while most equipment in the UK is designed to operate optimally at 220V. VO systems reduce this voltage to a more efficient level, usually through a transformer-based device.
