All round great company

Very competitively priced, with helpful staff that knows their stuff. They went above and beyond to correct a mistake I made on my order. I will definitely be purchasing any future solar requirements from them. My only regret is not finding them sooner, I would have saved a fortune.

It’s my second victron charger, and most likely I won’t go any larger than this. It’s responsible for charging a 150 amp 51.2v
