We recently had a call from a client in Ratby, Leicestershire, reporting that one string of a dual string inverter would trip the Trannergy PVI4000TL solar Inverter when isolated.
C Gascoigne visited the site and the system was checked and no solar PV fault was found. However, as part of the system check we did discover a faulty main RCD which was was located on the house consumer unit which would not trip under any circumstances.
This could have left the customer and his property in danger if left unattended. The RCD unit was replaced from stock on the day and the site left safe once again. This is an excellent example of why testing should be carried out at regular intervals on all Solar PV systems.
