Will this work on every house?
Voltage Optimisation is appropriate for the majority of properties. For homes with already low voltage supplies you might like to consider reducing the output voltage of VPhase below 220V.
The VX1 reduces voltage to a set level of 220V regardless of how high the mains incoming voltage rises (up to a maximum voltage reduction of approximately 30 volts). If the utility supply voltage falls to 220V or below then the VX1 enters bypass mode and stops reducing voltage. In these conditions the VX1 can not boost voltage so the site simply receives the same level of voltage as provided by the utility supply.
Some commercial Voltage Optimisation systems reduce the voltage by a set amount (e.g. a fix reduction of say 20V). These systems need to have a site survey undertaken to ensure that they do not reduce voltage at the site to below statutory limits. The VX1 regulates voltage to the set level so there is no need for a site survey. The output is 220V provided the incoming voltage is above 220V.
There is an additional risk with set reduction commercial systems that if the utility company reduces voltage too close to statutory limits, maybe for short periods or transient events, then the site could drop below statutory limits because of the fixed reduction of voltage. This would cause a “Brown Out” at the site. The VX1 does not suffer this problem. If the utility voltage drops below the VX1 set point then the VX1 simply enters bypass mode and the utility voltage is applied to the house.
