Problem solved
Having used customer service in the past when my problem was fully resolved I’ve got to say 100% satisfaction again. I had a problem with my Delta 2 not charging past 50% they sorted that that for me something to do with firmware update. Then a separate issue with my 160w solar panel that I was concerned about but after some discussion and a couple of pictures they replaced it under warranty. They kept me up to date with plenty of emails great communication. I’ve got to say I would not hesitate in buying from this company plus they have offered me 8% discount on my next purchase. Thanks again for a first class service.
