PV+ (PV Plus) Grid Voltage Optimiser

Description

Why Do I Need A PV+ ?

According to a recent report carried out by Western Power Distribution, over 50% of homes and businesses are supplied at a voltage level above 243.8V. Nearly 7% of these being supplied with a voltage above 248.8V*.

How does the PV+ help?

When generating, the inverter in your solar PV system has to increase its internal voltage above grid voltage (between 4 to 10 volts) in order to push the generated energy around your property or back to the national grid.

The increase in voltage can cause inverters to prematurely shut down on over-voltage settings. This results in a loss of generation.  The PV Plus can increase the yield from your PV system by up to 15% and prolong the lifespan of your inverter.

By monitoring the incoming supply voltage rather than the internal inverter voltage, the PV + unit allows the PV inverter to compliantly stay in circuit for longer. This prevents nuisance over voltage shut down and increasing PV generation.

Like all electrical appliances manufactured for Europe and the UK, solar PV inverters are designed to operate at 230V. Running inverters closer to their designed voltage will help prevent overheating of the appliance and increase its lifespan.

*Please note that the PV+ is only suitable for PV systems suffering from over-voltage shutdowns.
