I have been using another controller similar to this one for many years. It looks and behaves the same. I bought the original (which still works) to run a small solar power station in a remote hideaway. It wasn't a problem. I currently have another controller for my current system that works fine, but I wasn't happy with the information presented. I bought this controller to replace it because it allows me to see the battery and charge voltage, charge current, load current and the amount of kW consumed. I feel like this controller gives me a much clearer view of my system's health and usage. I don't need technical support and the controller is in a weather-protected location.
