Yeah, i am getting a 12v for my kayak, and thought maybe i can put it into use on those time i dont go out kayaking. I'll save up for another battery and will go w 2s2p then. I do have a little over 1k array. Thanks y'all for your comment.

Yeah, i would agree, but i only have 36v battery at this time.

Hello, my current set up is a 24v 100ah, 12/24v renogy controller, and a 24/36/48v inverter. I am looking to upgrade from the 24v to 36v, so beside getting another controller, is there any other way (budget preferred) to support charging my pack at a higher voltage? Thanks so much in advance.

My true problem is that due to my budget, my 100ah battery pack doesnt last the entire day, but yet, during peak hours, my array produces more and fully charges this pack, so the BMS stops taking charge. Since i have a couple of 12v but only 20ah (so i cant add them to the 100ah pack) and a...

Sounds interesting. But how can i do that? My current panel array is a 1kw, 60v i think, and i thought it might be too high for 12v scc. Are you saying that i can parallel at the main SCC solar input, another "Y connector"? Thanks

Ah i c. Thanks much

My current system is: panels to 24v SCC to 24v lifepo4 Now i want to also put a 12v and a small inverter to use to power some led. M my question, is there a way to charge the 12v with this system, without a AC charger that is. TiA

i currently have 3 lugs stack on each other and tightened up with a nut and bolt, but thought a breaker might be a bit better. but now, it sounds like i would be the only one who would put a breaker on the negative wire lol thanks for your response

Hello all, i didnt plan it out very well and found out that i forgot one more bus bar for the negative wire for 40a SCC + battery + inverter, but then i have a 50a breaker laying around, can i use that instead of a bus bar? so battery will be on one side while the SCC and inverters to be one...

this i didn't know. thanks.

nope. i have nothing else connected, especially the inverter. the SCC wasnt connected to my panels either. just the battery and the bms. is a 40a SCC considered a 'reasonable size capacitor'? it turns on instantly the moment i connect the wire.

Hi, so i just assembled my lifepo4 back, double check everything w bms and all. but when i connected the pos wire (neg has already connected to the bms neg) to the pos battery, i got sparked. nothing else was connected to either battery nor the mppt at the time, and i was 99% sure i didnt...

thanks so much again time2roll. so much to learn still lol

out of 8, one lowest at 3.226 and two highest at 3.231. should I put them in certain order? does it make any difference? thanks

I'm rewatching Will's videos, in this one, his pinned comment said: "Nowadays, you just slap a bms on the cells and it's good to go. It will top balance your pack and you don't need to think about anything. So don't worry about top or bottom balancing. Use a BMS and you are set."

in your first sentence, do you mean that i must get a bench top power supply? thanks

so, i am building a 24v 100ah pack with a 8S overkill bms and raw cell but just realize that i dont have a dedicated 24v charger. so question is, can i charge it via the mppt? i understand that it will take longer than an ac charger and probably take multiple days, but beside that, any reason...

thank you time2roll

no, i dont feel anything strange when i touch it, for now anyways. but in the future, what would be the worst if i don't bond the array? would all i feel are 'some juice'? thanks

the more i read about this grounding/earthing topic, the more confused i am lol. 'for dummies', can someone please let me know if i have to ground my panels. my set up: a few 36v panels laying on the ground (not ground mounted nor roof mounted), connecting to a mppt, then to the battery...

i don't know about the wireless sensor, but those SUN GTIL 1000/2000w has something that you might call 'fail safe' basically, beside the internal CT limiter that you can enable or disable, there is also 2 other options to put the 'upper limit': by amp or by power. so let's say the CT says...

thanks for a detailed explanation!!!

Hello, Another newbie question. So, my DC monitor reads 35v open circuit at the Mppt terminal when amperage is zero, but as soon as it starts to 'pull', amperage starts to rise, the voltage then drops to as low as 20ish. is this a normal behavior or do i need to upgrade my cable? i am...

yeah, i agree with all of your assessment. another question for you, what protection devices do you have for your setup? i see that a lot of people invested in SPD for both AC and DC sides but i also see that many ppl dont have any. Especially for a battery based like yours and mine, i m...

i only have one right now, just wanted to see how well it works. how's about you? and are you running it off a battery or straight from PV? i am thinking of building a 24v pack, still trying to find a good aliexpress seller.

thank you very much. i dont know where i got the idea that the leg side doesn't matter so i never tried. and yep, you are correct, changed the CT to the other leg and it appears to work now. and yea, i set the upper limit because the limiter didn't work. all good now. thanks so much again!!!

hello, i have this Sun gtil2 1000w that is supposed to support the limiter, but for some reason, it doesnt appear to be working correctly for me, unless i configured it wrong or misunderstood the number. my current set up: the limiter goes from Internal to one of the main leg in US 2 phase...

perfect!! that's what i hope to hear. thanks so much for confirming. and yes, the voltage limit is set by my Renogy mppt. thanks again

yes, 2 of the same panels per set. and that spec is per panel.

so, i have 4 mixing panels that I need to keep below 100v. with the follow specs, does it matter how my 2S2P should be (2S small panels in series vs 1 large 1 small in series)? i assume no since the wattage would be the same, right? but would like a confirm in case i miss something. tia...

wow! thanks much!

thanks. i actually wanted to diy it too. but from what i read, the eve cells from AliExpress sellers are kinda hits or misses, no? do you mind sharing where you get your raw cells?

no. yea, that was the reason for my question. although, adding a 6awg cable and a balacing device, the cost isn't too different. but i do have a 12v trolling motor, i might need this ability to take one out for backup. so i was looking for a strong reason to go with the one 24v. thanks so...

i am considering plug and play right now. ampere time to be specific due to budget. i dont need the low temperature cut off so i think I'll be fine w this.

they are both the same, 100a continuous charge/discharge, 100a bms
