Customer Reviews
Lights are on and running sweet. Don't look elsewhere, HB 21 is the only place for an alternative power source.
HB21 contacted me personally to discuss my email enquiry and provided a sound solution, as well as dropping off the products and discussing best application and installation. I am so impressed with HB21. I will post pics of the panel and controller install on my caravan once completed. Barry Kingston, Nelson.
So to put all the cards on the table, this is an Aliexpress product that's being imported and sold. There's talk about an app and how you can control it, but the team here haven't told me what that app that is when I've asked them. I have figured out what one I think it is based on reading a bunch of Aliexpress listings for this product and it works ok. The app is somewhat average and disconnects regularly. The actual charge controller itself seems to work well and do as it says on the pack. The plugs were wired in reverse when I received it but it was fixed after returning it.
