Thanks very much!

It's a bit more of a search here in the US but I think I've found a supplier or two who has small power supplies like that. Is it really as simple as just setting the output voltage on that power supply to an appropriate voltage (14.2?) and hooking the battery up directly to its output?

That's actually a bit large for what I'm considering. Here is an example of the battery I had in mind...

That is the intention! The router doesn't need 120vac anyway. The second part of it, the "programmable charger" is where I am trying to learn. It would be quite easy to just run the router off of the battery. I just need to figure out how to maintain that battery in a way that the battery...

Hmmm... OK. Thanks for the thoughts. It sounds like the charging part of it is going to be the most demanding part of the whole thing and that my little wall wart probably isn't going to get the job done well. I think I may have confused a BMS with an actual charge controller. The...

I am wanting to build a small 12 volt UPS, specifically for and only for a household router. It runs on 12 volts. There are some lithium ion powered 12 volt mini UPS setups out there for not a lot of money but I had wondered if I couldn't do a little better than that. Reviews on them suggest...

Thank you for sharing. Lots of data there. I hadn't seen that site before but I'm pretty new here.

This thread is about as close as I see to what I am wondering about myself so I didn't start a new one. I'm hoping one or two of you guys have already been down this road. I've seen Will's video comparing several solar panels and in order to "shade" them for testing purposes, I think he placed...

Thank you all for the input, and the actual experience doing what I'm contemplating. It is helpful! It also sounds like it need not be all that expensive, either, which is great! Yeah, those motors / fans will make some noise. In their automotive applications, pretty much no one cares about...

Hmmm... each of them should be pulling about 120 watts so I'd guess they'd be running a good bit slower from just a 65 watt panel. (??) One thing about it, they'd run much quieter. Interesting.

Interesting link at Amazon. Same fan as an electric automotive cooling fan and cheaper without the little "Solar" sticker slapped on it. I've wondered about using something like those. They move a lot of air for not a whole lot of electricity. Here's a question I have about a setup like this...

Grid power would be handy, no doubt. It would also be over $2k before I could get the little dancing power company electrons. Plus, I really would rather not have another electric bill. It sounds like I might be able to go the AC route with panels, charge controller, and inverter but I'm...

I know what I want to accomplish but I think there are multiple ways to get there. I could use some advice in sorting it out. Goal: Greenhouse exhaust ventilation. What I need to happen, I need to move air when it is hot. It is hot when the sun is shining. It is not hot when the sun is not...

Thanks, guys! I appreciate the feedback. :)

Thanks! I was kinda hoping it was either a typo that got corrected later on or I read it wrong.

Do half cell panels play well with MPPT charge controllers? The reason I ask is because I read a comment, somewhere, that I had thought suggested this was sometimes a problem. I have looked and looked trying to find that comment again but have not been able to find it. I've seen a panel on...

Thanks for the input. About the only concern I'm pondering is whether a 2000 watt inverter is large enough to cover the surges I might expect with inductive loads, some would be, and the potential for two loads starting at once may be too much for it even if it's quite enough to run them once...

Thanks for the input! Is this the inverter you're talking about? Definitely economical at $250. https://reliableinverters.com/products/2000w-power-inverter-12vdc-24vdc-or-48vdc-to-120vac-pure-sine-wave-inverter-rbp2000wstock-available-in-united-states

Thank you! That info is helpful and I'll poke around looking at those options. I saw Will's review of the EG4 6500EX yesterday. Looks like a lot of bang for the buck there, and it seemed to impress Will, which I imagine isn't that easy to do. That's probably larger than I would want most of the...

Have been looking at specs for various "solar generators" online and think that something like the Bluetti AC300+ 1*B300 system could do well for what I would like to use it for. There is no need for 220v electric and it would never be hooked to any kind of grid-tie setup. It would primarily be...

It sounds like your well pump is one of your biggest problems. I thought maybe I'd throw out a thought. Could you put in some kind of storage tank that you could draw from with an RV water pump or similar to provide you pressurized water when you need it? If you could run a generator...
