I recently had an issue with my solar battery not working and contacted Sustain for help. Their response was exceptional from the very start. They arranged a visit at very short notice, and the level of communication throughout was first‑class.
The engineering team arrived promptly, quickly isolated the fault—which turned out to be a communication cable back to the CT clamp—and replaced it with zero mess or disruption. Everything was handled professionally and efficiently, and I was back up and running in no time.
A special thanks to John, who organised everything seamlessly, and to Sam, whose expertise in identifying and fixing the problem was outstanding. It's rare to receive service this good, and I couldn’t be more impressed.
Highly recommended!
