6 FAQs about [Photovoltaic inverter power supply installation acceptance]

What type of inverter do I need for a mains-connected PV system?

Inverters for mains-connected PV systems should be type approved to the Energy Networks Association’s Engineering Recommendation G83/1 (for systems up to 16 A). NICEIC operates a Microgeneration Certiﬁcation Scheme (MCS) which covers the design installation and testing of environmental technology installation work associated with dwellings.

Should a PV inverter be isolated from the AC?

However, to allow maintenance work to be safely carried out on the inverter a means of isolation should be provided on both the DC and AC side of the inverter (Regulation Group 712.537 refers). In all cases it is essential to ensure that the PV system is securely isolated from the AC installation.

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.

How do I isolate my PV system from the AC installation?

In all cases it is essential to ensure that the PV system is securely isolated from the AC installation. At least simple separation is required between DC and the AC sides of the PV supply system to prevent DC fault currents from being fed to the AC side.

Should a PV system be isolated before electrical work is performed?

A PV system is an additional source of supply, so both the mains supply and the PV supply must be securely isolated before electrical work is performed on the installation.

Can a contractor install a PV system on a domestic installation?

However, where electrical work, such as the addition of a new circuit or the replacement of a consumer unit, is carried out on an existing domestic installation that has a PV system connected to it, the contractor may not necessarily be familiar with an installation connected to an additional source of supply.
