Fronius solar inverter replacement-Twycross

As a Fronius Service Partner this enquiry originated from the Fronius help desk.  We were informed that the Fronius inverter had fault code 417 showing which indicates a DC card failure. The customer was offered a replacement DC card with a 1 year warranty or a replacement Fronius Galvo 1.5 inverter with a full 5 years’ manufacturers warranty.  In this case the customer decided it would be prudent to opt for the latest technology and have a new solar inverter.

This was also rectified as part of the inverter replacement/relocation work. Fronius solar inverter replacement and repair

Leamington Spa Solar PV fault diagnosis and fix

SMA SB4000TL solar inverter - Inverter showing intermittent insulation resistance fault, (fault code 35).

C Gascoigne were recently called to a site to locate and provide solar PV fault diagnosis on a suspected fault as PV cable connectors were left unsecured in puddles of water on a roof mounted array. We are currently waiting for a dry day to re-attend and safely remedy the problem.  It was also noted whilst on site that the panels had been mounted with the diode boxes at the bottom of the panels.  This may lead to water ingress as water flows down the cables and toward the boxes instead of away from the boxes.  The array frame has also been installed directly onto the felt roof, this would benefit from being installed on rubber matting to...
