Post a close up photo of your meter, including the dial showing what range you are using.

Nice job! What temperature delta are you measuring across the inside coils? (air temp coming in from the top vs out at the bottom. And at the max cooling level, what is the coldest temperature you are seeing on the output? I've got an Pioneer 12K unit I installed I think back in 2016 that has...

Is the heat coming from the fuse or the lugs and cable? And how are you measuring the drop across the fuse? If your resistance is in the connection, your fuse will not show the drop, but from the lug to the fuse it will. Or from the fuse to the wire in your cable. Are you able to pierce the...

Vote here for Rectorseal White. Amazing stuff - I don't use teflon tape anymore after finding it 20 years ago. No more weeping joints.

Thanks Dave for the confirmation that the wire looks like it does even further back. So this isn't an overheated crimp issue. I wonder if certain types of insulation used an additive that would do this as it aged. I've taken up repairing old tube radios and see this a lot with wiring inside...

First one has been working fine. It's paralleled with other 24V batteries, all together 650AH. The second 24V 100AH has yet to be connected up as I don't have long enough jumpers yet. I did perform a capacity check on the second unit. Fully charged it to 28.0V, then discharged it a 4.5 A...

Bare copper can look like this over time and when exposed to air. it doesn't have to get hot to do this. I had to throw out some old spools of wire here that looked like that when the insulation was stripped off. It didn't even get used. Strip back the insulation a lot more and see if it gets...

Late to the party here. How many pumps does it take to make a crimp with this tool? I was going to get the TH0020 tool as it is single motion, but it is out of stock on the Temco site (10% off there) plus this hydraulic one is a lot cheaper.

Ecoworthy LFP batteries are 20% off on Ebay again. I picked up another 24V 100AH battery.

I was looking to buy the TH0005 but wonder if making smaller crimps with a hydraulic is a PITA having to pump it so much. Victron with 6ga wiring, and 2 gauge between my batteries, those are not huge conductors.

the nub/tang on the removeable side takes care of retention. My 24/1200 came with a mangled retention pin on the connector. I had to bend the plastic back into shape to work like it should. I use a Wifi smart switch with a cell phone charger plugged into it which then powers a small relay...

Will, what crimper are you using and are happy with it? What's its capabilities? (or a link to a video if you have one)

I’m seeing $100.03 right now for the 500A version, $110 last week. Victron msrp pretty much makes everyone charge the same price

I have been happy with my 24/1200 Victron, except I cannot charge my EV at 10A. I get that it's over the 1KW rating (1.2KW), but for others running theirs for an hour at 1150W, in my case it is only for about 10 seconds at 1200W. One nice thing about the Victron too is the low fan noise. I'm...

Deal is confirmed. $159.99 for the 12V 100AH (which I measured at 107AH using my CBAV with a 10A load), and $335.99 for the 24V 100AH. All are after a 20% Ebay coupon. Note that taxes are charged on the full amount.

Wow! Those are great prices. Hopefully they go through them thoroughly before shipping

Looks like Eco-Worthy is repeating their 20% off sale starting tomorrow (7/15) on Ebay. Right now (7/14) their ad already shows the 24V 100AH is "$335.99 with code", but there isn't a code yet. I think I'm going to get another 24V 100AH. I rearranged my packs today and have room for 1 more.

I installed a Pioneer 12K 200V unit back in 2016 and had problems that were never resolved. It works great when it very hot outside (90+), but poorly cools with lower outdoor temps. You'd think that wouldn't be a problem but it is since the house heat soaks during the day and at night when you...

Victron Smart Shunts are already on sale for $100 https://www.amazon.com/Victron-Energy-SmartShunt-Battery-Bluetooth/dp/B0BF636VBX

I have been enjoying their $1.50 Global shipping choice. $2.00 for 5 boards + $1.50 shipping + tax comes to about $3.76 total. I send my gerbers on Monday and I get the boards in my hands the following week on Thursday. Heck, the speed of US First Class Mail these days isn't even that fast...

Distilled water rinse, followed by Isopropyl alcohol rinse, followed by compressed air, then bakeout at 60 C for a few hours.

You must mean toner transfer method? I tried that decades ago and switch to doing the photo method and never looked back. I buy pre-sensitized boards and within an hour I can make a PCB with 10mil lines/spaces repeatably. That said, if you can wait 2 weeks, you can get boards made cheap, full...

Which Temco unit did you buy? I have a large crimp tool I bought from McMaster-Carr probably 20 years ago that has served me well, but it only really smashes the terminals from 2 directions vs all around.

I bought one of the EcoWorthy 12V 100AH batteries during the Ebay 20% July 4th sale. Was $149'ish before taxes. Didn't realize the ad said it was used, but what I received looked brand new. Charged it up, put it on my CBA V and measured 105AH. I'm happy. This will be for ham radio portable...

Interesting. I built something that does the same thing using an ESP8266 with an built-in 18650 battery holder, and a wall adapter that keeps the 18650 charged but also I can sense when it drops out. Of course I have to have working internet - which my equipment stays up so I should, but...

In case anyone is interested, DC House on Ebay has the 24V 100AH battery for $410 plus another 20% off for 4th of July. Taxes are based on the original price, so out the door for me with taxes is $360. I will not be picking up another battery though as I'm where I need to be already storage...

I can't help you on specifics, but you're on the right track. You have enough solar, now you just need enough battery so you're using up what you make first before going to the grid. Others will have to help you with the best way to do that. FWIW, I disconnected my 24/7 internet loads (modem...

Ah, yes - I know about the temperature dependence part of it. I'm wondering about permanent or faster degradation of the panels themselves. Mine are flat mounted and I'm pretty sure they're looking different than when I first installed them 10 months ago. Cell borders a little more discolored...

Ammonia cycle refrigeration is so darn cool. Almost black magic

Sensors a binned for performance (NEdT) but a lot of times the differences between models are just software features (auto vs manual AGC, different LUTs), better pixel operability specs (number of bad pixels and clusters allowed). The MSX feature is awesome on the FLIR models though...

Could you please elaborate on this? I think I'm seeing evidence of not having enough but I want to hear what you mean first.

Also didn't read the whole thread, but the opening post was "I use 175 KWh per month" and "I have a 3.7 KW system" and a "$500 true up" You should have a zero bill with your system if it's working correctly for as little energy you are using (<6KWh/day)

I've been happy with my 24V 100AH EcoWorthy. Bought another Victron Smartshunt and have been using it to measure the performance of individual 24V batteries in my setup. Even the DLJBERMPW 24V 100AH has been working great. No issues with early termination of the charge (though I do terminate...

Was it the 12V mini?

No issues with mine. Sounds like your lugs are not very thick or your bolts are too long.
