A traditional Solar PV Installation can often be wired so that the output voltage from the Solar PV Invertor is fed into a spare way on the Consumers Distribution Board, along side all the outgoing circuits to the dwelling.
To enable the Electricity generated by the Solar PV system to be fed back into the grid, the Solar PV Invertor will have to step the voltage up above the existing mains voltage.
The problem this can have with a traditional wiring configuration into the main distribution board is that all the appliances within the house are now subjected to an even higher voltage than the original mains voltage.
For electrical dependant loads this can mean they consume more power due to the increased voltage being above and beyond what they need to function correctly and the extra power ends up being Increased losses often generating heat and often shortening the electrical life of expensive appliances.
To the consumer this means higher electricity bills and a reduction in savings from their Solar PV Investment.
All Electrical Equipment in Europe since c1992 now carries the CE mark. This means that all electrical appliances must operate on a voltage range between 207V and 253V. The optimum voltage is 220V so any voltage higher than this is where the waste is generated and result in un necessarily higher electricity bills.
Apex Energy UK have designed a voltage optimisation unit to work specifically with Solar PV Installations and will optimise the voltage to the house ensuring the appliances are not subjected to the higher voltages as a result this reduces the total load drawn from the house and means more of what is being generated by the Solar PV system can be exported
