thx Bud. I mean the charger switches off. I am not even using the actuator in this test. but now that you ask , I have had luck using using the standard PA-14 https://www.progressiveautomations.com/products/mini-linear-actuator, at worse case it's about 5A, lifting up.. going down it's...

I am looking for a module that I can use as a 12V (around 5A max) power supply that will fall back to a simple 12v 6Ah type AGM. My intent is to power the Raspberry PI circuit that I use to control the actuator that I use to open my chicken coop door. At full load these devices could use up...

Thank you all. Your help was invaluable. I posted a writeup of my project at. https://vinthewrench.substack.com/p/building-a-standby-power-system-for

good question.. the DWPH EFC-06E12D is a generic 3 wire fan.. red/black 12v - yellow is the tachometer. One of the fans was wired only for power and the other one had the tach.. the Noctua was a direct replacement, though I had to reuse the original cable. The inverter is quieter now . What...

Quick question of practicality.. Assume an array of batteries in a outdoor battery box, going to an inverter. which should be closest to the battery in current flow, the fuse or the battery disconnect switch? I am tending towards the disconnect switch (big Blue Sea SPST) first and then the...

reposting this without the saga. https://diysolarforum.com/threads/fan-on-freedom-xc-1000.25124/ basically I had a piece of hardware that was to dammed loud for use at home. I replaced their crappy fan (DWPH EFC-06E12D DC 12V 0.60A 60x60x25mm Server Cooling Fan) with a nice quiet Noctua...

I finally gave up on their tech support - damm the warranty for something that is an engineering mistake. I replaced their crappy fan (DWPH EFC-06E12D DC 12V 0.60A 60x60x25mm Server Cooling Fan) with a nice quiet Noctua NF-A6x25 https://www.amazon.com/dp/B009NQMESS. so much better now.

I just got this spam

Many thanks, I shut it down for the moment.. i bet I can get a reading of db from my iphone.. I will try to that later today. i have some photos above showing the setup.

It's hard to say. I have the smart-shunt setup, and I have seen it run the fan with no current flow to the battery, I have the float set at 13.5v. and have tried it lower, How low would you suggest?

One more problem, is that you really need the remote and bluetooth to do proper setup. The built in UI is difficult. The bluetooth has to be set each time you want to run the app. maybe they could have done a better job here.. The Victron folks who make the smartshunt seems to have gotten...

Not getting the best help out of tech support - they suggested that the transfer relay is what might be heating up. to recap- I basically have a UPS setup to drive some computer/sat gear, running somewhere between 100 - 300W, sitting in my living room. The battery is at full charge and the...

I am glad you had no mishaps. there is risk in everything we do, but we still need to get he job done. hope my tips help the next guy have an easier time. I recently had a discussion with some fire fighters about how they handle cutting holes in solar roofs.. pretty amazing stuff
