6 FAQs about [Photovoltaic power inverter wiring standard]

What are the requirements for photovoltaic (PV) generators?

Requirements for Photovoltaic (PV) Generators (currently in development by IEC TC 82) – will set out general installation and safety requirements for the PV equipment. The Scope of Section 712 in BS 7671:2008 includes PV power supply systems including systems with a.c. modules but, currently, excludes any form of battery storage.

Which inverter is best for solar panels?

String inverters or centralized inverters are the most common option in PV installations, suitable for solar panels wired in series or series-parallel. Centralized inverters convert DC power for the whole string, which is why they are recommended for PV systems not subjected to partial shading.

What is a photovoltaic system?

Photovoltaic (PV) systems are unique. Common logic used in other methods of electricity generation, such as motor generators, wind turbines, UPS and Stirling Engines cannot be applied. Significant changes are occurring in standardisation at international standard level where PV systems are concerned.

What is a solar panel inverter?

The solar panel inverter is one of the most important components in a PV system. This component converts DC energy generated by solar panels into AC energy at the right voltage for your appliances. The output is a pure sine wave, featuring a 120V AC voltage (U.S.) or 240V AC (Europe).

Are there any UK standards relating to a PV installation?

While many UK standards apply in general terms, at the time of writing there is still relatively little which specifically relates to a PV installation. However, there are two documents which specifically relate to the installation of these systems that are of particular relevance:

Where should a PV inverter be installed?

An inverter supplied from a PV array must preferably be installed in a dedicated circuit in which: no current-using equipment is connected, and no provision is made for the connection of current-using equipment, and no socket-outlets are permitted. An inverter must not be connected by means of a plug with contacts which may be live when exposed.
