Well after several Discussions and listening to several people On here I have decided to go with a 48v system. The big bonus with this is I will save over $700 on wire from my panels since I hav s 230 foot run and wiring my panels 3S2P will allow me to use 6 gauge wire vs 2 gauge wire. I...

stay with me, I'm just throwing out my thoughts but. I was playing with the solar calculator looking at the best angle for year round, my results were: Summer, 70 degrees Winter, 40 degrees best year round angle 55 degrees. I understand 55 is half way between 70 and 40, I get that, splitting...

Hello all, I am new to Solar, trying to build an emergency/part time solar system, to run a few things all the time and have power when my power goes out or SHTF. I'm kind of building Will's, 4,000 watt system and improve on it if that's possible, I know the solar product world is changing...

Sorry, I'm reading and tying to learn, but here is my question. a 120amp overkill BMS will support 1536 watts, I get that, but how does this work if I have three 24 volt batteries (24 cells, wired together) I understand i will need 1 BMS for each 24 volt battery. so how much power can I pull, or...

So I am planning on driving to signature solar in Texas tomorrow and picking up 10 of the Solarever 440 watt panels. I am new to this and realize I don’t know what I don’t know. Is there any reason this won’t work with Will’s 4,000 watt 24 volt solar blueprint! It uses 2 40a mppt...

I am trying to calculate my solar panels amperage, I understand the formula, but I'm not sure which voltage to use? VOC? VMP? VMPP? these are all close, but I need to be accurate. or is IMPP the Amperage, my panels say: Max power current (IMPP) 9.93a Thanks in advance.

Looking for suggestions for how to haul solar panels, I have a trailer and plan on going to pick mine up. I know glass trucks usually transport glass on its side, but how's the best way to haul solar panels? believe it or not I could not find one single video on how to haul solar panels on youtube.

Hello all, I'm in Arkansas USA, and due to my neighbors trees I loose the sun this time of year around 3pm. I get great sun up until 3pm starting at 9:30am, but at 9:30 the sun is more in the east and not hitting the panels at a good angle. So my question is given my circumstances wound it be...

I am currently putting together my system and learning as I go, I'm curious of the advantages of a 48V system over a 24V. I read somewhere you can use smaller wire, but which wire is this referencing? I did not see that info needed on a wire sizing calculator for my wire from panels to Charge...

I cant seem to find a diagram, so I'm thinking it may not be possible, but I am considering going to 48 volts, and I have 24 cells that are 3.2 volts each. can you configure 24 cells to get 48 volts?

I have 10, 440 watt solar panels and 6 280AH lithium batteries, Do I have to many panels? how do I calculate this? or does the charge controllers limit how many panels you can use?

Need some help guys, im looking at a Samlex 24 volt 3,000 watt inverter. it has a max input of 180Amps I am running 3 24 volt 280AH LI batteries in Parallel. Battery specs says Nominal discharge 140A, max discharge current 280A Each 24 volt battery is made up of 8 lithium ion cells, to make a...

I am trying to built my own system and learning, I am trying to calculate the size wire needed from my panels to combiner box, and from combiner box to charge controller. my specs are 6x440 watt panels WIRED 2S3P VOC 52.6 VMP44.3 ISC 10.53 IMP 9.93 its about 12 feet to combiner box and 230...

Looking for some recommendations for a reliable 3,000-4,000 watt 24 volt inverter for 120V house. Guess you could say i'm building a small system for a cabin. I want to run 2 inverters for redundancy so If one dies I still got 1/2 power. I have 5,280 watts of panels 2 Midnight 150 charge...

Ran across these on ebay, out of Texas, $2,090 for 10 (ten) 440 watt panels (47.5 cents a watt) made by Solarforever out of Mexico 12 year warranty 25 year 85% Linear power warranty 9 busbar Solar Cell UL listed 20.25 model efficiency VMP+IMP =440 Looks like a good deal??? only 4.5 hours...

Looking for opinions on these 2 inverters? Or better comparable options in the same price range. (Working on a budget)

This may be an odd question but I have six, 12 V batteries and I’m thinking about going with a 48 V system, but I’m not sure if you can wire six of those batteries to get 48 bolts?

Well I am leaning and building, I think this is correct except for things I don't know, where all to put fuse's and circuit breakers, wire sizes etc. I even bought a Solar book, trying to learn. any advise or suggestions would be appreciated. any advise or assistance would be greatly appreciated.

Need math help. I have five, 440 watt panels with a 49.7 VOC each and I’m trying to string all 5 together and keep the VOC below 150 which is the max of my charge controller. Will wiring them 2s3p accomplish that?

I have a question, I have wired my cabin 2 ways. I have grid power and outlets and stuff but I have also ran a completely separate independent set of wires into most rooms for my solar. These wires are not connected to the grid in any way. I want my solar and grid Independence and away from...

Hey the link in the YouTube videos for Eve or Lishen cells go to Vericore cells? Where do I get the others or am I missing something, I’m new and just learning. Thanks.

I'm trying to calculate the size wire I need from my panels to the CC. but im not sure how to calculate or what to calculate? I know the specs of my panels VMP 40.99 IMP 9.93 ISC 10.53 VOC 52.6 but do I use this or since my panels are wired 2S3P would I then use those power numbers? Anticipated...

Looking for ideas for putting all the equipment and batteries in an out building, would like to see pics of your setups as well ideas as to if this is a good idea.

I need help I have read that The EVE-280AH Cells can discharge up to 1C-Rate or 280A for a max of 1 hour? 1st question, is that 280A per cell? with lets say 4 cells in a 12 volt battery, I believe the answer is no, that number is for a 4 cell 12v assembled battery? 2nd question, not sure how...

Hey guys, I need some help, I'm new and learning, I'm wanting to build a system with (8) 12 volt batteries to get 24 volts and i have been googling but cant find much on how to do 8 batteries? would it be like in these pics, just basically add more batteries to the center (in between the top 2...

So, I was playing on the solar calculator and I notice in the pics at the bottom they are measuring the degrees from the panel position to the vertical position. I thought you would measure your degrees from the horizon? is the pic correct?

I was looking at the SMA inverters and I don’t see any 110 V ones? Everything is 240 unless I’m missing something? Looking for a 24v to 110v Quality invwe’re.

Hello, total newbie to Solar, been reading a lot and tons of videos, so much to learn. I read my 1st step should be budget, I would like to stay under $6,000 I'm building an emergency or SHTF power backup for the house. 2nd step is I'm trying to size my system, I've found the files here about...

So I got a Kill-a-watt devise to measure my energy usage. After 48 hours and 42 minutes it shows 1.26 KWH used. But now I’m stuck trying to figure out how to calculate how many watts an hour I’m using? I think it’s 29 watts an hour but that’s seems low for a deep freeze? Anybody here know the...

My system is almost complete, I'm down to wire and connectors, where is everyone buying their wire? are there cheap resources??? thanks in advance
