Reviews

  1. Richard Collins

    The support I have received has been excellent. Though it’s early days in using this, so far it seems to be a very good product

  2. S Copeland

    Terrific bit of kit from a British Company. Always prepared to give advice and guidance. I had the 11amp version first on a 140w panel and used it on my motorhome for 3 years. A new van and 240w pair of panels has meant an upgrade to the 15amp version.

  3. L Draycott

    Excellent product! So easy to install and neat! I had an old one of these fitted on my old Motorhome and it worked great. I bought a new large RV and wanted to keep both the coach battery and leisure batteries charged. This does it perfectly with a 160w solar panel. What I love most is the display as it tells me how much charge I have in the batteries and if I am wild camping I know how long I can run the batteries before I have to switch to the generator!!

  4. M Chinn

    Great unit, it looks good and maintains the charge in my two campervan batteries without any fuss or bother. Straightforward installation with no set-up configurations to worry about as the unit automatically sets it self. Clear display provides all the information you need at a glance. Sunworks provided me with email confirmation of my order and delivery date. Unit arrived on time and well packed.

  5. B Cooper

    I have just upgraded my solar regulator to the Sunworks 15amp charger, having had one of their older versions installed on my yacht for years. A truly excellent product, never faltered and easily the best looking unit on the market; taking pride of place alongside my recently fitted switch panel.

  6. C Dally

    This is an superb product much more sophisticated than the older model I have used for last 9 years. Great service and delivery and much cheaper than I paid 9 years ago so would rate this product 5 star plus. Colin

    I did a lot of research into which solar controller to fit with my new 2 x 100w flexible panels. I was cautious about buying a Far East made controller on quality and service backup grounds. I finally chose the Sunworks dual battery controller, because I heard good reports yacht owners, and the fact that it fits flat to the wall without wires showing. Before buying, I had a number of queries about the controller which were answered promptly by Sunworks by email, so my confidence started to grow.

    The controller comes with clear instructions written in good plain English – not a Far Eastern translation! When you open the pack, the controller looks good, well designed, and I could see that it would blend well with the between decks decor my Hallberg Rassy yacht – full hardwood interior.

    Fitting was straightforward, and I am not an electrician. Having followed the instructions and connected up, the controller light up immediately, separately telling me the voltages of my engine start and domestic battery bank, together with the rate and what type of charge it was performing.

    Since fitting, one of the first things I do each morning is to look at the readout with a satisfied smile knowing that any power we used overnight has gradually been replaced from dawn, and there will be no more low battery problems.

    An excellent, good looking controller, which is easy to fit – look no further!
