The first one I had went bad after a few months, it would discharge but not charge. Ernest was great, he supported me, stood behind this product, and eventually replaced it.
If I did it again, I might consider a purely electrical BMS without all the complexity of these Daly units; the Daly units are very full featured but with that comes complexity.
But that said I'd highly recommend Lifepo4oz as a vendor. Obviously, I've had some issues, but you can call these guys on the phone, they pick up, and they help you. There is a lot to say about that when you are spending ~13k on an off grid setup. I can't imagine my frustration if I'd have bought my kit from a faceless online vendor and something went wrong. Lifepo4oz are a good crew. Recommended.
