SKU: LVX6048 Categories: ,



A lot of these issues are actually caused by battery BMS being too fully charged , and the battery subsequently goes open circuit , causing instability.  Usually lowering the bulk and float voltage to reduce this chance.  also over discharge the batteries can also cause instability and failure .


Some of the issues in parallel mode: (we do not find these issues [as much]  running as single units) – this should be fixed by the firmware above.


This unit REQUIRES 240V Split phase to charge from AC power  (will not wake up with 120V only)

This LVX6048 is the latest member to MPP Solar’s 120V/240V Split Phase inverter family.  Adding several important features from our 220-240V European line, this inverter becomes the only low voltage model that offer these 7 valuable features

  1. High PV input up to 450V, allowing more serial PV connection
  2. Built-in WIFI transmitter to support monitoring on smartphones
  3. BMS communication for Pylontech, Soltaro and Weco battery systems
  4. Grid interactive (grid injection) may be enabled wherever it is allowed
  5. Battery optional – use PV panels straight to load
  6. 120V/240V split phase output without needing to parallel
  7. Parallel capable up to 9 units (54KW max)  ******
  8. Parallel kits required to connect more than one unit in parallel  (sold separately)
  9. This unit is not UL listed  (there will be a LVX6548WP waterproof model in summer 2022 that will be UL)

Note, max PV input amps = 27A. (If you panels put out 10 to 20% more than this, it will just pull a max of 27A,  a little bit of clipping at mid day, thats all)

Note this is a low frequency product, high surge capacity,  with a built in auto transformer, offering 3kw per phase

  1. Horizon Energy Systems (verified owner)

    We installed this unit on our customers home and they are thrilled with it.
    No grid tie and soon to add some LiFePo4 batteries to the system so they can store generated power for night running of mini splits for heat.
    Support from Watts24/7 is always available and an extremely valuable asset when you need help.

  2. John and Lisa Goodfellow (verified owner)

    Bought 2 of these for my 48V solar project and couldn’t be happier. Watts 24/7 has been extremely responsive and helpful with every question I’ve asked, including advice with my solar array and battery banks. Support from MPP Solar has timely and accurate when I needed them as well. We love our LVX6048’s and all of our Watts 24/7 products and services.

    Installed in machine shop and is doing very well running 2 mini splits.

    I have had these inverters running now for 5 days. I really think these are working amazingly the grid feedback seems to be working well. The only thing is that you really need to read the setup parameters carefully. If you really don’t know the answer stay with the default. My first day was spent really understanding the settings and getting them right for my batteries. If you are using the BMS function your install will probably go much smoother than mine. That being said since I figured out the battery settings for my older SOK batteries its working better than expected. I’m running 2 LVX’s in parallel and they are pushing large startup loads with ease. The AC compressors seem to kick on nicely without any soft start installed. So far I’m very happy with the results. I haven’t done any firmware updates yet. I haven’t had time to get that end working yet. I will comment further on this as time will allow.
