I hope you write up and share @how you assemble it all as that sounds like a great project.

After discussing with the household, we decided to switch pumps to one that includes dry-run protection. We also verified the batter will operate at 105°F (it's good up to 122°F). Got a sanity check on the length of hose. All seems reasonable on that front. Always good to have a buddy check to point out these things. ❤️

Did you plan this out? I can show you what I use for my pig waterer since I'm on v2 of the prototype.

I did, and then we swapped the model of pump once I realized we need dry run protection and didn't have it. We also verified the battery will operate at 105°F (it's good up to 122°F). Got a sanity check on the length of the drip irrigation system's hose. All seems reasonable on that front. Always good to have a buddy check to point out these things. ❤️ What did you change the second time around? And why?

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.

This has been on mind for ages, similar setup, but without the need for solar or any pumps A tank on an elevated platform A hood to capture rain water And gravity fed drip system Just thinking out loud

That's what we tried initially, except we ran the house gutter straight into the rain barrel. If you can find a drip irrigation system that works with low pressure, let me know. They all seem to be designed for hose pressure.

True, the pressure from gravity fed source might night be enough, especially if you have a larger area to water Maybe splitting the supply to different areas could help

That would lower the pressure. The best solution would be to find a solution that works with low pressure (larger holes and increasing in size along the length of the hose to account for the pressure drop of each hole).

What I meant was that you split the garden into two and have a barrel or a tank for each half and not split the pressure

That doesn't help. If you double your capacity with a second tank, you have the same pressure. If you have two tanks with the same total capacity, you have even less pressure. In either case, it's not going to come out of any normal soaker hose or drip irrigation system. The only way to get more pressure would be to have more water capacity. It's the weight of the water that is supplying the pressure. How much water is needed to get an acceptable pressure? I don't know, but I can tell you that 305 US gallons is not even close to enough.

I read somewhere it’s more about the height than the weight, so you can have your tank at 25feet and that should give you about 10psi So it’s about the elevation, but then how do you get the water to that elevation, either your garden is downhill and you collect rain water from your roof and then irritate or you you pump the water to an elevated tank to store the energy and then irrigate
