No clear link to health, but glad you're verifying system specs.

Boat bilge pumps are cheap, readily available, 12V and include a float switch to turn them off when they're dry.

Yeah, I have the dry run protection in the pump. Caught that one before buying the pump, as my initial choice fell short there.

Fuck I didn't get notified you responded. Main thing I changed was my timer is mechanical, all the digital ones I tried don't last outside. All the rest was simply hardening my connections and actually using a junction box. I got one of those car lighter type outlets for the junction box for ease of plugging and unplugging the pump becauce my setup is mobile (watch out for a finished project today or this weekend) and mounted on a dolly. I also got a more heavy duty marine battery enclosure so that my connections can stay outside of that case and I don't have to rely on the battery level shown on the charge controller since that's inside the junction box. I'm using the same pump as before because it worked phenomenally before and can pump up 100feet since the highest point of my property is slightly higher than 100feet above the lowest. I got a different brand of charge controller, but I don't remember it off hand, if you want to know I can check when I'm working later. I plan to mount the solar panel on the dolley but want to leave it off for a month or so to see how I can do that without ruining my ability to drag the dolley around my property with my uTV.

Looking forward to pics of your rig. If you have a suggested annalog timer, throw it at me. I orders a digial one, but if/when it fails, I'll know what to try as a replacement.

Well I got derailed today by the sheep, but still hoping to finish by the end of the weekend.
