I needed to be able to make parts with high temp materials so I finally broke down and got a resin printer. DLP Elegoo Saturn to be specific. The material I'm using here has a working temp of 160C so should be more than enough for diesel heater duct parts. This thing is a work of quality of I...

"Germany is adding greater risk to its playgrounds. Some of its climbing structures are now three stories high. And who is requesting this? Insurance companies. They want kids to grow up "risk competent." Ironically, "safety" culture is stunting kids' risk assessing abilities, in their...

Someone posted a sale on 105AH cells a few months back, and given the price of roughly $150 for 4 cells I figured I don't have much to lose here. Am running individual cell discharge tests at 21A and already am seeing the expected falsely advertised specs. The first cell is ~84AH. The voltage...

This came up a few times in a few threads but I just came across this ad on Facebook for plug in soft starts for power tools. Perhaps this will also work for the portable AC units folks have? Edit: orrr perhaps not at all. MAYBE since they claim it's software based they can develop one that...

Perhaps this is something I inadvertently caused but my overkill BMS just tanked from 235ah to 154ah while I've had a constant ~6 amp load. Screenshots show a time period here of only 8 minutes. During that time I updated my low temp cutoff setting and nothing else. Bug? Is this a known issue...

Tight on space. Manual says to mount these things with 10cm clearance and terminals facing down. Well. Sorry Victron but space is limited. Good thing is I'll almost never need to use the DC to DC charger. Gooder news is the space this will go in is rather significantly ventilated. If I have...

Got my overkill attached to the cells to get the lay of the land here before doing all my top balancing and testing. Noticed the app says "protection none" on the dashboard. Is that something else entirely or do I need to somehow enable the various protection parameters that I can see already...

I have a victron mppt scc. As many know they need +5v above battery voltage to enable. Does the open circuit voltage come in to play here when the scc is checking for this +5v each morning, or is it the nominal connected voltage?

About the same way I do, to be honest.

So. Here's a thing. I'm impressed by the effort so far into this install. I won't post the location because it's nobody's business though. These panels went in recently nearby. We were heading north at the time of the photo, so they're facing south and slightly west. This in and of itself...

WI state parks don't allow generators regardless of whether they're the quiet inverter type. They do allow you to sit there and idle your vehicle all day long and play music all day long for everyone to hear. I'll never understand it. Of course that means I can use my vehicle as a generator...

I'm reading the Multiplus 24/3000/70 data sheet and it states an acceptable input voltage of 95-140VAC and 45-65hz with an output of 120vac +/-2%. The sheet doesn't explicitly state it will turn a poor quality shore power source (say, 100v) into a stable 120, however these specs seem to...

Step one of building my custom cargo trailer conversion obtained. Actually I bought it for other reasons. As part of my mech E course work we had a hot work class which covered the basics of everything from oxy-acetylene and plasma cutting to brazing and welding with stick, two types of mig...

Alright. I'm doing some budgeting here as a just in case scenario. If my cells show up and they're particularly bad I would like to simply utilize them for my 12 volt backup sump pump (and then order some from amy). Since it needs to run pretty frequently if the power does go out, it would be...

I have 2x 20w and 1x 10w panels on my tongue box. This was done due to the odd size of the lid resulting in overhanging of a single 50w panel. Currently there are no fuses on any of them. Of course this means low fuse ratings are required. So I started looking... Are fuses even needed since...

Edit: nope. That won't work. How can I delete a post?

Hey. First let me say I love the fact that there are so many electrical engineers here. I'm a mech e student and journeyman tradesman myself and I dabble in control wiring for injection molding and automation equipment fairly often at work. First time slapping together something with Chinese...

Yeah. But this is very misleading.

Newish to solar, but not really new to electrical stuff. I am hoping to find more information on these types of panels and what alternative brands there are to renogys eclipse, if any. My google-fu is letting me down in favor of marketing hype. In a recent video our solar overlord Will posted...
