Is there any options for diy batteries?

Thanks

Not sure, hopefully someone else can help with that. I have the JBD from overkill solar.

Well I got my 2 units installed last night, this morning I double checked everything and then fired them up. They seem to be working flawlessly, I just ran a load of laundry through the washer and had zero issues. My LVX6048'S power really gave my washing machine a problem. I had zero dimming of...

My 2 units arrived. Thank you @currentconnected. Merry Christmas to me!

Is there a way to build a water turbine to power this battery charger? The AC input is AC90-240V + 20% (see attachment) What components would I need to get the input voltage within this range? Would I need a dump load or cutoff switch if I went over or under the voltage? Any other info is...

My shipping label was created today! 2 units on the way.

Yes it will increase.

Just remember to allow for the coldest day of the year ever recorded in your area. Your voltage goes up the colder it gets.

I believe you can do it that way with this inverter. If you want to play it safe, you can run 4 into input 1, and 4 into input 2 for inverter1. Then on the 2nd inverter you can run 5 into input 1 and 5 into input 2.

If you have 2 mppt inputs per inverter then you can split up the 9 panels between the 2 inputs and you won't go over voltage. You would go over voltage if you ran all 9 panels in series to 1 input.

4s2p to one inverter 207v 22 amps 5s2p to the other inverter 260v 22amps I'm assuming your roof angle will not give you the optimum angle to get max PV production so the 22 amps figure will be higher than you will actually see and that is the short circuit value, not the actual value of 20.4...

What size capacitor would I need for mitigating power dips and spikes when larger loads start or stop? AC, stove, washing machine, etc.... Also my washing machine does not like the power output from a single LVX 6048, it does better when I run 2 in parallel but it is still not working properly...

Just wanted to say thanks to all that helped me through my journey into solar electric freedom. Today my system produced 27,280 watt hours before it filled my 1200ah 48v battery bank. I've been off the electric grid for a week now. I have 6.6kw of solar panels.

This makes since because I just brought the 2nd inverter online and haven't done any configuration on it yet. Thank you.

All the wires from the battery to the LVX's are the same length. But to what you said, I can get 80 amps from the large array going into the battery, while the small array has yet to put out more than 5 amps before it gets cut off by the difference between them.

I have 2 different solar arrays, one is 5520 watts, 6s 2p running on 2 wires down to the house to 1 LVX 6048. The other is 1440 watts, 6s running on the other 2 wires to a 2nd LVX 6048. When the sun comes out strong the small array cuts wattage power down to basically nothing, but when it's...

Here's a close up

As in an X pattern?

I just checked again with a different cheap multi meter and got different results. Apparently it is a bad meter. Thanks for the help

They were connected to the inverter, I get DC voltage as expected, when I check between the AC L1 and L2 lug and each wire I get 120vac

I measured from L1 lug and L2 lug from a running inverter to each of the 5 wires.

I ran a ground wire to ground the frame, but I have not connected it yet.

They are mounted on a wood frame and the panels don't make contact with the ground at all.

2) Ok, positive and negative wires to PV panels. I get DC voltage from the panels when checking the positive and negative wires like you would expect. I was getting a shock touching the panels and kneeling on the damp ground after I hooked up the panels to the inverter a couple days ago so I...

I'm in north America

Yes, hot and neutral to solar panels. And a ground wire to bond the solar panel frames back to the main earth ground.

Did you ever figure out if it was AC induction on the unterminated wires? I'm having a similar issue and trying to troubleshoot the problem. My lvx 6048 seems to put out AC voltage everywhere. I measured 100v AC voltage from L1 L2 to my garage door track, I also measured 83V AC to a random 5ft...

I'm assuming I have a short somewhere but I'm also a little stumped. My solar arrays are 400ft from the house. I ran 5 wires through plastic conduit, 2 hot, 2 neutral and 1 ground. I'm getting 120 AC voltage on every wire even though they're not connected to the LVX 6048. I get voltage from L1...

Here is what I'm referring too.

I'm pretty sure you answered a different question I had about fusing or using a breaker on the positive or negative side of the battery bank, you told me the positive side needs to have the breaker. No mention of the negative cable in your previous answer. I'm just a newbie trying to figure it...

I know this answer is late, but if you go to the parts on Will's 48v off grid schematic in the menu tab (top left corner of this page), he has a link to a 200 amp dc breaker that will do what you want. It's from signature solar, you can just take out the copper busbar they are using to make it a...

Yeah, at this point I don't plan on doing any kind of substantial capacity testing. I am at almost a month of constant charging to get them sort of top balanced. (Close, but not all the way to 3.65v) I just need to get the system running.
