Lol. That would be too difficult; but, yes, he can lower the amps going in simply by either lowering the charge voltage or limiting the charge (he can do that with his charger, but rather coarse adjustments - maybe in about 1A increments). Thanks!

Hahaha.. . Yeah, I know. I told him he can borrow my benchtop power supply, but says his pack is too big and heavy and not easily accessible after he put it in there. Ah, well...

The Daly BMS only disconnects the charging portion (one can still discharge), so basically, my friend will just not get to fully charge the battery until it balances out. The battery is already in service, but, instead of, say, charging to 280Ah, he probably gets to charge to only 250Ah (because...

A friend didn't top balance his cells. I would have lent him my benchtop power supply, but he didn't know I had one, and now too much hassle for him to disassemble pack (rather tight location and all that). He did connect them in parallel for two days (but reading in this forum, that didn't...

That would be high frequency inverters vs low frequency inverters. Or toroidal. They each have their own pros and cons. I used to be a big fan of the heavier ones as well. Still am. But high frequency transformers have come a long way. Am not an expert on them, so others will have to chime in.

I'm not going to out and out say Deye manufactures for Sol-Ark, but there's lots of indication that they do. Everything including the interface looks the same. Lastly, and it may not hold weight, because while Deye doesn't say it directly, their distributors do. If you try to get Deye from...

My understanding is that Deye manufactures for Sol-Ark. Sol-Ark may have requested for other features for the USA (and puerto Rico) markets. Check out also Sunsynk (also made by Deye). The distributor of Sunsynk made a video of a factory tour, and the factory was... Deye. Dunno pricing of...

I only put essential loads on the inverter, and my big appliances (like old A/Cs, heaters, etc) are still on the grid, and the inverter does battery grid sharing (like a slow, steady release). But, of course, if you're completely off grid, that doesn't apply to you.

http://www.batterysupports.com/60v-672v-57v-20a-lithium-ion-lipo-battery-charger-16s-16x-36v-p-444.html That looks like a 57.6v charger (maybe can even be set to other voltages), but not a balance charger like the one for RCs.

Do they come in 16S? If not, then I guess I still need the BMS.

Am very interested in getting a BMS that can be programmed to communicate with the Deye/Sunsynk/Sol-Ark inverters. I know there are batteries that can communicate with them (Pylontech, Dyness, Meritsun, etc), but those pre-built power walls are pricey. And this is, after all, a DIY Solar...

Haven't actually watched this (2 hours long) And Sunsynk website has the manuals (under tech support and downloads) http://www.sunsynk.com/ (better manuals than Deye website, but since they're essentially the same thing...)

It does that, too. You're talking about exporting to grid and net metering, right?

Took about 10-11 days. Hit 3.5v and stayed there (when I saw it, current was very low, like 2 amps). Put it to 3.6v, and within 2 hours if I remember correctly, it hit 3.6v. Disconnected the power supply, and after 30 minutes, it was still about 3.55v, and after about an hour, it was still 3.5...

Local guy (Philippines) makes these dongles for less than $50. He makes for many inverters and solar chargers so that people can wirelessly monitor their inverters/chargers via the Internet. I lent him my SmartShunt and he did some programing, and, voila! I can now monitor my SmartShunt...
