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!!!

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

thank you time2roll

You guys are geniuses. I left the battery in the fridge over night (a bit impatient, i know lol), then waited until it reached the room temperature like u said, and now, it is being charged like a brand new bms lol Thanks again for ur help.

Ah i c. Thanks much

So i have an 18v ryobi battery that wont charge. While there is no voltage reading at the terminals (.4ish volt), reading directly from the battery shows 18ish volts. All individual battery also reads 3.7ish. Does that mean my BMS have gone bad? Anything i can do? Edit: pics attached Thankz

thanks much. they are on the ground, 'Will's style', laying on a couple of paver blocks lol.

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...

thanks. it is without the panels. do u know the diy (milk crate that will did) lets me charge and consume at the same time?

thanks for a detailed explanation!!!

i see. i would agree with your assumption, i see a lot of youtubers talked about that, so i thought perhaps it might not last as long as an enphase, but is it that risky to use it, especially when i know i will be using it below its rating. (1000w peak array / 1500w max input) the inverter...

thanks! yeah i dont expect 100%, but didnt expect it to be too low either. I'll test each panel as u suggested. thanks again.

thanks, that makes sense.

lol, yeah, basically. i got that same brand, but with higher voltage and 1300w. this forum doesn't seem to want to deal with non UL GTI, so i didnt want to bring it up, but that's the only I could afford. it's been doing ok with 2 panels setup, but now i am trying to figure the best way to add...

first of all, please be gentle as i am a total noob lol. So i have a few panels leaning against my wall, planning to set up with a MPP all in one (so voltage would be up to 100vdc). from what I read so far is that while the all in one inverter will share the ground with the AC (?!?), i will...

i dont understand leakage current, is it like one of the factor for the power loss? when i first set it up, i did a quick measure between the two ends, from DC to AC, i think it was like around 75% to 80%, which i thought was ok. most of the time, i just monitor from the AC side. for example...

hello all i am considering a 24v setup and thinking of going with Ampere Time. they have 2 versions of the 100ah and i was wondering if anything i should be considering beside the size, the convenience of having one vs two, and an extra wire to series connect them, but being 'stuck' to a 24v...

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."

i have 4 panels basically laying on grass in my (residential) backyard, with some woods and bricks to help tilting, do i need to ground them? i don't think Will ever mentions with his on the ground set ups, am i wrong? thanks

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

the thing with my house is that i don't see the house ground rod itself. when i traced the ground wire from my main ac panel, it comes from outside of the basement wall, which is underground. so i was wondering if i can just "t-bone" connect to that main ac ground wire or not. thanks

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...

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...

do u guys have any recommendations for a $500 budget? i have no other requirements beside the budget, just want to play around. preferredly one that can charge (via solar) and discharge at the same time, if it is a possibility. thanks

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...

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.

oh... are you suggesting me not to bother with grounding/earthing the solar panels? sorry i am a beginner, so I just want to make sure. thanks

i have 2x 20ah (for now) rating lifepo4 and approximately 1kw array, what is the max load can i power during the day? beside the inverter and charge controller, is the battery still my constraint in regard my max load? for instance, i am planning on getting a 60a mppt, a 24v 1000w PSW...

yeah i know that the current battery cant accept that high current, but i thought it is the negotiation between the charge controller and the bms, ie if the battery doesnt want to draw that much current, then the controller wont put out too much, is that a wrong assumption? i want to start w...

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.
