Hey guys, I have a LV6048 with 4 100ah LiTime and a 16s 100aH system both at 48 volts. I took the LiTimes off, because I needed to test something else. Last night, I plugged in my EV and went to bed - the 16s was around 54% charged. I woke up and the truck was at 1%. I walked outside and the...

I found that online.

This is how this would work? How big should each fuse be?

Ok, so to do 12 I would need 4 strings of 3 panels in series? Then all 4 wire pairs into a combiner box?

Voc- 40.25 Vmp- 33.05 Imp-9.38 Does it give a temperature coefficient? Temperature Coefficient Isc %/K 0.03 Temperature Coefficient Voc %/K -0.30 Temperature Coefficient Pmax %/K -0.38 Birmingham, AL

Ok, I am looking at 10 310w panels. I can wire them in series for 100v and 40.25a. The panels have a series fuse of 15 and a short circuit current of 9.93. If I am understanding correctly because my Isc is below my series fuse amperage I do not need to fuse? Or, am I missing something...

Ok, this is a serious question - would 8 panels be enough? I can buy 8 or 16. I just want to push the inverter as far as I can.

Ok, so 4 2s2p into the combiner box and then into 2 wire pairs - 1 into each input?

It does have 2 MPPTs - https://shopsolarkits.com/products/mpp-solar-lv6048 - I had to check. I should run 2 2s2p not 2s4p?

1. Is this correct? 2? The combiner box would go where here?

Hello everyone. I have a LV6048 and I have found some local panels I want to try. The LV6048 - The panels are REC360AA - By my math, a 2s4p would give me Solar Array Wattage: 2880W Temperature Compensated Array Voltage: 98V Controller Output Amperage: 50A Array Short Circuit Amperage...

Thank you for the response. Are there any units you would recommend that fit these parameters?

My house has a split unit on the porch. I have been thinking of building a 240v system to power it in the summer. I am a bit unsure on how to calculate needed wattage and battery needs. It only needs to work when the temp is over 90 - I live in Alabama. Voltage 240 Freq 60 Max Fuse 25A

I am working on a tool to give the user the most efficient way to wire his/her panels. It has worked with my testing, but I would love any feedback or suggestions. I have no plan for deployment - I really just made it because my classes are over and I was bored. Thanks in advance -...

Do y'all mean that both + and - wires go into it, or that I do not wire it backwards?

I'm open to any brand/type. That was just the first I found.

So, something like this? https://www.amazon.com/LANGIR-Photovoltaic-Polarized-Circuit-Certificates/dp/B012MWNSTS/ref=sr_1_11?crid=VN42APK5ZAUS&keywords=DC%2Bbreaker&qid=1682713122&sprefix=dc%2Bbreaker%2Caps%2C81&sr=8-11&th=1

The AC is running off a 2 pole 40a breaker in my box, and the batteries run through a massive fuse. It is funny you said that. I thought I saw a small spark when I was checking the screws last night.

Wait, I do have a Blue Sea switch. Will this work - https://www.amazon.com/gp/product/B07H8573R4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

I think the biggest I have on hand is 80a.

Can I do it without a disconnect? I have all the rest of the pieces.

Ok, really weird. Someone in another thread assured me it was 250 max v - I looked forever and all I found was the 145v. I have attached what I believe is the correct wiring diagram. Can you point me to a combiner box that will work for 2 2s2p strings? I plan to buy 4 more if this half is a...

Ok, I am finally ready to wire my first high voltage system, and I want to be sure before I do it. I plan to wire 4 Tallmax 335 in series into one side of my lv6048. I've been watching videos and reading forum posts, but the order of things throws me off. Currently, the system is running on...

That is what I am thinking. It will be under for the max wattage, but it will charge the batteries to charge my truck over night. EDIT: Also, will I need a fuse? Max Series Fuse Rating - 15A

VOC is 46.3

Ok, you can never see my setup. Yours is so clean.

A local seller has some new Tallmax 335 panels - VMPP 37.9, IMP 8.84 EDIT: VOC is 46.3 I have an up and running LV6548. It looks like I can run 3 in series at 114V and 8.89A. So, 9 would be 3015W. Is my math here correct? Would I need to fuse each group of 3?

Sorry to bring this back from the dead, but it is good info and it worked perfectly.

I will run those tests. Thank you for all your help.

At about 5 minutes under no load, it seems to be doing fine.

Funny you ask that! I had left my Ford EV charger plugged into that wire. When I test tonight, I will follow your sequence and unplug the charger.

5. Yes 6. This is its new error (attached) Everything seemed to be working fine, and then it started to beep. Does it think the batteries are over charged?

Ok, so I went back this morning and worked on it. 1. Pre-charge capacitors 2. Turn on battery breaker 3. Wait 4. It kicks on the output 5. I turn on the breaker 6. After about a minute it starts to fault Is it possible my setting for 11 is too low? I'm pretty sure the breaker is a double 40...

Yes, it is hooked to 4 12v Ampere batteries at 48v.

Sorry, phone was acting up. I came back to do some troubleshooting. Now it is giving fault code 56 "battery connection open."
