Thanks! But, that didn't work when I tried it with my twins. Oh! He doesn't have his set to run split phase. If I simply parallel my twins, they will charge on single phase input. They will not charge from utility if I set them to output split phase.

Another update: I did get the twin 3048LV-MKs paralleled. They do output 240V when configured that way, both via inverting from the battery and being fed 120V input. I don't have an easy way to test their load capacity in this configuration at the moment, but, meter checks do show 240V output...

Yup. I'm going to be limited with what I can do on the roof, since I can only fit 4 panels of the current type up there. Once I move elsewhere, I'll be able to install a ground mount system and will simply add that to the input of the second 3048LV-MK. But, yes, I'm expecting to see more total...

Yes. But it's doable You don't need to use the transformer post AIO. You just need it pre-AIO in order to get charging. No minisplit should draw anywhere near that much juice. You should be focusing only on inverter compressor minisplits that slowly ramp up the compressor. Not exactly...

Well, mine are essentially flat mounted in an RV roof... So there's that. LOL This is the first spring season with the system and is all new, so I'm looking forward to seeing how it performs as the seasons change. ☺️

Another update on this: With the cold, clear days with a sun higher in the sky, I've had several days of sustained, higher than sticker rating output from the panels. It's honestly been shocking to see how well just the two panels are performing when it's cool/cold and sunny. The peak, so far...

There's two things you can do: 1. You can figure out how to program the units easily so you cab run one inverter normally to limit your standby consumption, then if you need the second to come online, you set the first one to parallel mode and power on the second and you should be in business...

I'm starting to poke around my own 3048LV-MK setup and am still at the beginning of understanding how it works. Have you made any new observations since this post?

This is great to know! Thank you. =)

I'm currently running an MPP 3048LV-MK. It would be nice to have battery coms, but... I don't find it necessary, yet. The voltage input on the pv suites my needs better than the EG4, and, it's less expensive. So far, it's been working very well with only two of my four panels installed and I'm...

I really enjoy that about this forum! Thank you. ☺️

I've had a few days where input has peaked much higher. This is fascinating to me! The sun is finally high enough in the sky to clear the roof peak. When the trees start to leaf, that will kill early mooring production, but, the peak should more than make up for it. With just the two panels...

Thanks again for the additional feedback! This is all so very fascinating to me!

So fascinating! Thanks for the input! 😊

Dang. That's wild. I am still very new to all this, and the learning curve is steep and full of twists and turns that I certainly wouldn't have figured out on my own!

Hi, all! I got some fairly strange numbers today that I would like to have some feedback on. Is it possible to get ~725W input from two REC 405W rated panels (two in series currently for 810W nominal) in February in Pennsylvania? That works out to be 88% of the rated capacity, and I find the...

I have a few updates. I poked around the forum and found some suggested settings for these kinds of inverters, and, well, let's just say that they were effective, even if the cause is a silly firmware bug in the 3048LV-MK that is never going to be fixed. That being said, my goodness am I...

The reason for this is that on low power with heat guns and hair dryers, the method of running half power is to simply use a diode to cancel out half of the AC waveform, which will REALLY make most inverters not happy. When switched to full power, the whole AC waveform is used to run the...

Thank you! Everything is working well so far, though, I'm having issues figuring out what to use to separate the cells before I tape them together, but I know I just need to search a bit more.

I just topped off the battery pack again and I'm very pleased. Only .003-5V deviation ABC settles down to a reasonable voltage. I need to pick up a few things to more permanently affix the cells to each other, but, so far, the cells and the BMS work exactly how I'd expect them to work!

I'm building my first pack now: I still have a lot to learn, but, it's going well so far!

It's been a while, but things are escalating nicely. I've got two panels mounted on the roof, the 3048 working with the solar input, plugged into an outlet, and have had it running with the 20Ah Moseworth batteries. Nothing crazy, but, just proving the system. I recently bought 16 105Ah EVE...

16 cells acquired from 18650 for a surprisingly good price. Let's see how quickly they actually ship, as I've already got the notification. Thanks, @42OhmsPA!

No, I hadn't. Thank you. That's even less expensive even with shipping. Sweet!

Hi, all. I'm looking to put together my first big (for me) battery with these cells: https://eelbattery.myshopify.com/products/4pcs-eve-3-2v-100ah-genuine-grade-a-lifepo4-cells-lithium-ion-solar-energy?variant=40146648465497 EEL seems to have a decent enough reputation, and with free shipping...

Right. Dang. OK. Time to suck it up, then. Thanks!

The reason I ask is that I'd like to test the JKBMS that I bought, but honestly don't want to hook up the balance leads with the cells I have on hand for a variety of reasons that I'd rather not elaborate on at this time. If they need to be hooked up, that's fine, I just need to know so I can...

It's possible, but, for the money, it still isn't a bad deal.

That would be helpful, wouldn't it? https://www.amazon.com/dp/B0CBJTR9LL?psc=1&ref=ppx_yo2ov_dt_b_product_details

I popped the insulator off the BMS. It has a temp sensor on the board and looks fairly proper!

I took a chance and bought 4 of these to put together a test battery pack for setting up my MPP 3048LV-MK. Today I decided to pop the top off of one, as I wanted to see if the internals were decent, as the batteries have been performing rather well in my testing. I did buy a JKBMS to use for...

In case anyone needs this info in the future: Running on battery with the inverter on, my 3048 is drawing 32W.

Thank you! I do, too. I am more confident now since I have got the wiring figured out.

Most of the time, I don't notice my converter, but, that's a pretty good point! I hadn't thought of that. My AIO is under my bed, but I haven't noticed it yet, and that's before I enclose that part of the pass through with Cement board, which should help even more with noise.

Update time! Stage one complete! I forgot to get a pic of the screen showing solar input, but, the 3048 is in the general area where it will live. The reason why it took so long to get to this point is that the factory wiring wasn't connected to the gland on the roof. I had to figure out...
