no, actually those are for the thermistors that are built into the packs. once I pulled out the built in bms, I kept the thermistor leads in case I ever wanted to use them in the future. at the time, I was way more concerned with temperature than I am now. so much of the worry out there with...

the ground isn't really meant to carry current for any length of time, it's fine to use a smaller conductor for the job. for instance, I run 240v AC about 100' to my house from my inverter, for that I use 4/0 wire as the conductors. the ground, however, is only 6awg. it just needs to be large...

I have three of the six batteries online at the moment. Because the house loads are more "gentle" than their previous jobs, the batteries are doing much better than expected. Things I have learned: When I bought them, they were being sold as ~2.2kwh, per unit. I'm seeing about 2.6kwh per due...

I don't even pretend to know what it all means, but we had an engineering firm spec everything and wet-stamp the plans. they insisted that it was over-spec'd for the area and conditions. they were more concerned with the wind-loading on the long sides, actually, since the building is long and...

three 5" x 18" LVL for the ridge beam, supported by two posts, consisting of 5" x 9" LVL. those transmit the downforce to the floor, supported by a gigantic 28" x 16" LVL beam that runs the full 24' span.

The SIP panels that make up our roof are 12-1/4" thick. The EPS foam that cores the panels makes for some pretty good noise insulation. Our roofing goes up this coming Tuesday, but we've had some hard rain in the week since the panels have gone up. I went out to listen to the noise, and TBH...

awesome advice! we just received our standing seam roof (24ga) yesterday, and it's due to be installed next week. what would you recommend for fastening the rail to the roof seam?

I'd second this as an economical choice. use the factory oil for the first thirty minutes, and then switch to a high-quality synthetic -- it's worth the $8. I've run mine daily for ~2h (to charge the batteries in my worksite tent, using a 24v multiplus) for the last 8 months and it's super rare...

That's actually pretty doable. I'm playing around with pulling the data from multiple Daly's over the BLE (different packs, wired in parallel) and collating that to send to my victron quattro. Doing the same for PylonTech-speak shouldn't be all that difficult, and would still work with my...

tryb try accessing the bms with another phone. you'll see that the password doesn't matter. the physical bms has no concept of a password, it's just some weird thing they did in the app.

yep. it's due for an update -- been busy building a house. here it is.

Ah. I do remember reading this! (thanks for the link, btw.) I don't think it's going to be much of a factor, because my system isn't ever grid-tied, and my inverter is grid-forming -- basically, you can't rely on an inverter to reliably use frequency shifting if it can't completely control the...

I'm about a month away from having the full array up on the roof. That said, I have setup a small test system with three panels and have had great success with that so far using just the frequency-shifting. I was planning to setup one of the quattro's relays to control an AC dump load and to...

My situation is, well, a little weird. We bought a 100+ acre chunk of raw forest, that had as it’s only existing infrastructure a stubby stretch of 150’ of driveway. If we were retrofitting batteries into a place that already had some existing buildings, amenities and such, I’m pretty sure that...
