Case Study: TRUE DC Isolators within Commercial PV Arrays

ZLC Energy is a Cornish company based in Liskeard that specialises in providing zero and low carbon energy. They are a team of multi-technology consultants and installers that are trained to above industry standards, with experience of designing complex integrated systems for commercial and domestic clients.

As leaders within the zero and low carbon energy provision industry, ZLC Energy needed to source a range of TRUE DC solar isolators to compliment their photovoltaic offering for customers embarking upon either new-build, retro-fit or updating their existing technologies. Reliability was of paramount importance to ZLC Energy in order to maintain their own quality brand, and the SI range of TRUE DC Solar Isolators by IMO ticked all of their boxes, especially in regard to reliability.

Since 2009, and the launch of the first ever TRUE DC isolator with UL508 approval, IMO has been manufacturing solar isolators of the utmost quality and reliability. The SI range has surpassed an astonishing 6 million field installed units, with ZERO reported electrical failures, and the success of this range has led us to develop a compact version (called SIM) which offers a 35% reduction in overall size, yet offers increased ratings and extended mounting options. The SIM retains the high reliability technology of the current SI Series including knife edge contacts, high speed operator independent switching mechanism and full arc control with guaranteed suppression time.

The high quality manufacturing processes of the SI range are now ensuring the ZLC Energy is offering the very best to their customers.


" We use IMO products for consistent performance, reliability and availability. High Performance products supplied at Competitive Prices. We have used other isolators in the past and have had to go out and replace these due to catastrophic failures.
The IMO True DC Isolators do exactly what they say they will. We find them easier to install and have peace of mind that once installed we can almost fit and forget".
