Great! Remember, now you can use that same setting, 3v down from actual batt V to switch "modes" any time you want. That is what I did when I started with the 6000xp. I just left enough capacity in the battery to be able to not waste any PV the next day, depending on clouds/weather. The...

Are discharge voltage curves different between prismatic and pouch cell LiFePo4 batteries?

Thats what drills are for.

Long sobs of autumn violins wound my heart with a monotonous languor Molasses tomorrow will bring forth Cognac The chair is against the wall

This is what I think may have happened.

signature solar. Arrived via fedex, no damage but crushed cone on top

Zoro just shipped my order.... 1 Hour and 40 minutes. That's all it took lol

YES, I have a lot of 48v light bulbs that I plan to use in any scenario that requires strict power rationing. Lights without the use of an inverter is KEY.

Thanks for this. I just purchased one and when it gets here I am going to give my ESS a colonoscopy.

Its Renogy, I would consider this greater than "remotely possible" :)

I have to say, at least we are not all using lead acid. That has a whole big box of "ifs" and maintenance. I am sure there are plenty of people on this forum that would disagree but, I am young enough to not have had much to do with lead acid. I am glad for that!

No problem. Think of it like this. The shunt cannot see anything that isnt passing thru it. The way I think you had it connected looked like it was counting all of the energy going in the battery and nothing coming out.

Right! That is a lot of power for cheap. I dont understand why this is even a question. An hour of my time is certainly work $400. Sig solar, 100AH 48v is $1398 5.1 kWh DIY 16s Eve with BMS $1790 13 kWh Its not even close!

Somewhat disagree with "Humans are very skilled at getting ourselves out of problems when our butts are on the line!" Not much faith in group think or humans in general over here. :)

Thanks for testing this.

It is a battery with 15 internal cells instead of 16. It has a charge voltage of 54.75v instead of 58.4, Almost every voltage chart I read is irrelevant because of this. Almost every battery is 16s so I cant put them in parallel with mine. Cant use any preset on anything. Need to make sure...

Regarding EMPs. If you have advanced notice, whatever mitigation efforts you try, DO NOT think everything is fine after the event. Most likely there will be 2-4 strikes even days apart to make damn sure everything is FUBAR. Best to lie low for a long while after.

really? I never knew it was like this! But I just got a couple mppts and the shunts and the usb dongles and their weird cable and useless bluetooth thingy and their.... BUT I stuck it to the man and made the poor mans cerbo with the Ras Pi

Lol, I got those shelves. That would never work. Its sagging with just the empty boxes. :)

RIGHT! not worth it in my opinion. November to Feb is almost worthless where I am so there is not way Id be using the inverters for much.

No way! hahahah

You can get a genesun solar charger at whatever voltage you want. https://sunforgellc.com/product/gvb-8/ These are super small, light, and awesome. You would probably select the custom voltage option. The link is for the boost converter. You would only use this with a PV array at LESS than you...

Did you hear that California is giving free Medical health care to illegal visitors?

Well,I guess they paid me $50 for being the early adopter. Its a great unit. I am pretty sure it does work as a stand alone mppt It has a separate on switch for the inverter part. So Im sure it will draw much less working in mppt standby mode. The inverter switch will not turn back on by itself.

Oh my! I never..

The same as the pictures that were posted minus 2 cells. As far as the JK BMS, you would simply need to make cell 16 vacant, not cell one or any other than cell 16 What happened to the cells??

I am not sure what to make of this. You have batteries connected? No frowny face on the 6000xp?

Well, no, there isnt anything more useful then those. If your bill is 1300KWH, you need more than 11KWH array in order to make that work with cloudy and crappy days. Winter in wisconsin I would want at least a 25KWh array to possibly make 1300 The best idea is to figure out what you want to do...

all of them

Hi, I have had a 6000xp for a couple months and certainly have seen this. I have seen 50 watts of input shown going into the BATTERY while it was night time not the PV IN tho. It turns out this is because I was using grid and bypassing the battery. I imagine this occurs because the inverter...

Ok cool, check that off then. Your bus bars are rated to 300 amps and you can max pull 270 amps with 2 6400xps. (6000w/44v) They might get warm :)

They are fine. you have about 1200 watt hours, You could mostly charge that (80%) on a good sunny day with 2 100 watt panels.

wow, ok. Didnt know that

That is the frustrating part. Having to look in 4 places for things... 3 of which, the web page, and the app and the "direct connect" TCP look very similar and its confusing! What I ran into was that I was setting the battery EOD voltage above the "battery warning" voltage setting that only...

This should happen naturally with your On grid EOD setting where it should be. Take note that if your battery triggers the on grid EOD it needs to be 3v higher than that votage to release. That may be your entire problem. It was my problem at first because I was playing around with the settings...

lol nicely put

VOLTAGE .. size and type has nothing to do with current voltage or general health.

The kilowatt meter is awesome and a lot of fun. I have tested just about everything in my house with the ones I have. A battery shunt is the same information but on the DC side. And is very useful to find out if your batteries are performing how they should be. You really do need to go full on...

Oh, you probably got one of those fancy ones with 1 SSID and the router chooses what to dish out. You can usually seperate the two and stop it from doing that in the settings of the router. If you can get into settings

If this is the case, you are perfectly fine. In fact, doing good I would say.

I would be pretty unhappy. I got mine at 18650batterystore.com and they are in fantastic shape. i think i remember .020 deviation at 3.1v when i tested last.

NO, you need to use a voltage setpoint without communication.

Ha! Thats the truth~!

I am certainly confused as to how that all happened. I like the way you put that tho . " That being true, Who over the age of 15 hasnt been told how to do something better? I think OP was very proud of what he had accomplished (strange to us) but that is the only reason I can think of for...

No, I rekon we all need 3000kWh to make it thru winter! That is where we all want to be! :)

Im right behind ya. I havent done a whole year yet.. Ive done june to nov at my old house and june to now at my new house. I havent covered all the months lol

Just checked them out thanks to you :) Looks nice but I am confused by the Charge/ Discharge numbers. Instead of 1C/1C its a says .5P/.5P What is a "P"???

Yes

That is right where my tiny house sits :) 70 amps. I have a 100 amp fuse after my buss bar.

They seem fine with 4 mounting points.
