I've been using this solar pump controller for my backyard pond project, and overall, it's been a solid performer. The setup was straightforward—hooked it up to a 24V submersible pump and an extra solar panel. The water flow is smooth, and my wife loves the tranquil sound of the pond now. That’s a win in my book!

One thing to note: the input voltage specs can be a bit misleading. While it claims to handle up to 50V, mine struggled with a 40V solar panel setup. Switching to a 24V battery backup fixed the issue instantly. So, if you’re relying solely on panels, double-check your voltage output.

The float switch feature works like a charm, cutting off the pump when the water level is too low. No more dry-running worries! The build quality feels sturdy compared to cheaper bulk modules I’ve tried before—no hiccups after 4 months of daily use.

The manual could definitely use some clarity, though. It assumes you know that a '12V panel' actually outputs ~19V, which might confuse beginners. But once you get past that, it’s a reliable little workhorse for shallow well pumps or pond aerators.
