MPP-Solar LVX-6048

Hi, be aware that when you feed the grid you are sending ac to the line. If you don't have a meter, then when there is no power on the grid your system will not feed the grid. Now when you don't have this special meter any worker can be in danger because you are sending live ac to the line or grid.

The user I quoted said they are already back feeding, so my assumption is they have the correct meter setup and safety features, but good point!
 
The main reason I chose the LVX6048 is that when the grid goes down it automatically shuts down grid feedback and only feeds my sub panel. The sub panel has our fridge, bathroom lights, TV & hotspot, you know the essential stuff! What I did not know was that it has to be UL listed to get the power company approval, that’s the reason for wanting the 6048WP. I am new to this and have done it all myself, just learning from you folks and YouTube.

Not sure where you live, but the first question burning on everyone's mind is how did you hook up grid feedback without getting approval first?
 
Well…that’s kind of why I want the WP, in case they say something about it. I am in a neighbor state of yours. But the HOW is super easy, a new breaker in the main panel wired to “AC in” on the inverter and setting 09 set to ”Gre” and it’s done. Since I live way out in the sticks I did not need any kind of building permit and I still have the old spinning meter because I signed a form to opt out of the digital meter. If I could afford enough batteries to run the air conditioning I would go off grid completely.

Nice! So does the old meter spin backwards when you feed the grid? The obvious issue there is if you back feed enough to have a lower number than the last read someone is going to be scratching their head.
 
I'm considering a purchase on a LVX-6048 as an emergency backup for my 11 year old off-grid 48V system with Xantrex/Schneider Electric XW4548 110/220VAC with Outback FM80 MPPT CC. The current system has run flawlessly non-stop (less battery replacement periods, etc) for over 11 years now, home use, not a seasonal cabin. My concern is that either the Inverter or the MPPT Charge Controller may fail due to their current age.
Would you folks here recommend the LVX-6048 as an emergency backup should either of the aforementioned existing components go down and need servicing?
It would only be used during repair periods for the current components.
I would never replace it with a voltronic base inverter, a DEYE hybride sound a lot more appropriate. ;-)
 
voltronic is the OEM for mpp..
they release the same inverters as voltronix axpert ( of which i have 3 , 8000 max) , as incould buy them within the eu, there by circumventing import taxes of 30% and that also gave me 3 years of warranty instead of 1 per EU rules)
you can buy them in EU for a good price at solarpower24.
 
Hi, the SolarPower APP does not work for me. The only difference since May is that now the three LVX6048s in parallel show up online, which they didn't on the first try, but the data on the APP is pure fantasy. According to the APP, I generate a huge amount of PV energy every night, and the values for DC and AC voltages and currents are displayed absolutely incorrectly and differently in the 3 devices.

Unfortunately, the SolarPower PC software does not work either. Many values are either displayed incorrectly or not at all. The data transfer to the PC also freezes sooner or later or the 3 LVX6048 disappear in the software.

At the beginning of my contact with the MPP Solar support team in May, the product manager Eric Hsioa and the support guy Andy Y. promised me a solution for all the reported bugs as well as for the monitoring feature. However, since the middle of June I have not received any more responses to my emails. On July 13th, after 4 unanswered emails, I asked again and for the last time:



They never got in touch with me again. No answer is also an answer. For me personally, that means that I burned $ 4,000.

So I wouldn't expect that the SolarPower APP or PC software will ever work on the LVX6048.
To my friend I say, stay away from voltronic base inverter. you can't trust a product coming with 1 yr warranty. if you do your research you will find out, most of their new hight power PV inverter has bug. mpp didn't design the inverter. buy an inverter with at least 5 yr warranty, from a brand where you can get in touch with the engineer staff.

actually, you should read up on EU warrantee rules dor this kind of hardware.
this is THE Reason i buy from italy

Yes, the meter does spin backwards! I was so excited the first time I got to see it do that! Our bill says we average about 41 killawatts per day and the panels produce 18-20 kw per day. I spoke off the record with a good friend who works for the power company and he said as long as I don’t have a zero bill then most likely no one will say anything.
 
Is there a base monthly charge for grid power?
Just to be connected to it?
Even if you use no grid power at all?

Hi, be aware, I am located in Puerto Rico during Maria and other hurricane lot of people use the power generator and they didn't had tranfer switch. There was some fatalities. You are feeding ac to the grid and you can be liable if something happens. You don't know wend the grid will lose power.
 
Long time lurker here, I have a sunny boy 3.8kw grid tied and a LVX6048 in the process of connecting. Has anybody successfully AC coupled on the load side of the LVX? I'm currently coupled on the grid side but would like to know if the grid gos down if I can safely AC couple to charge batterys
 
Quick off the wall question. The LVX6048 is perfect for my system in every way except for the lack of a UL Listing (I know the WP is a thing, it's just out of stock everywhere & double the price). I know that the LV6548 is very similar, has a UL Listing, but does NOT support grid feedback. Why can't it? Is the LV6548 missing some component or controller that I can add to enable grid feedback on the AC output side?

Im not sure about the hardware side but I know the software won't allow it thats how the make it UL COMPLIANT not LISTED and be aware it is 120v only until you have 2 or more with the 6548

That makes sense, and I just realized that the "ETL Listed" mark on the lv6548 is very much so not "UL Listed". And I am aware that it's a 120v system, and I would need them in pairs for 240 operation.
 
Lurking in this thread for a while. I may want to use the LVX6048 (NOT WP) specifically for a well pump (37a surge) and a deep freezer in the basement of a cabin. Looks like this inverter can handle the surge/well pump run no problem. My only concern is the inverter on consumption. Is it still in the 200W consumption range and is the inverter reliable?
