Please don’t cry to us when you decided to buy from an international/fake/copy seller – no support, no local warranty, no local phone number. (It happens all the time) 
There are lots of fake Chinese copies out there , perhaps saving you 100 to 200 bucks,  I say – go for it! Once bitten, twice shy.
We don’t sell proprietary modified equipment that ties you to a specific supplier for life (“not Network Locked”) thus firmware and hardware directly from the manufacturer (MPP Solar) will be supported by our products, Note: there is a proprietary version with 500V MPPT inputs that will “Hotel California” to that supplier for life (Firmware and Hardware)
The LV6548 is the latest members to our 120V/240V SPLIT PHASE inverter family and we are pleased to confirm it has UL1741 compliance (TUV certified) for US markets. Similar to the LV2424, a single LV6548 is a 120V output inverter, however split phase output (120V/240V) can be configured by using minimum 2 or more units in parallel.

  1. USA Warranty 2 years for our website customers

  7.  Each MPPT input is completely independent from the other, max 250V input per Input (4kw max array size per input),
  8. 120A Utility Charger (120A at 48V = 5.7kW or 48A at 120V)
  9. Built in Genset dry contact start/stop relay

    Since I bought my 2 LV6548 units, I had to wait for them to be in stock before they could be shipped to me.
    You shipped them BEFORE the estimated date, and they were Very well packaged, and they arrived in good shape.
    (Not too common lately)
    When I had a question about one of the PV inputs not showing up as any charging power, I was able to get directly to you on the phone, and you gave me the solution immediately.
    I don’t run across companies that under promise and over deliver like yours very often.
    I really appreciate how you run your business.
    Please keep up the good work!

    I have watched many videos for both Growatt and MPP. I am very please to have made the purchase of this unit from Watts247 and performed the similar no battery experiment and it worked incredibly nice! Do your own research and you will see why I chose this LV6548. There is one thing I want to mention that Ian, he actually responses to all of your inquiries, small or big. This is enough reason for me to continued my business with Watts247.
