Too good to be true? Exploring the idea of updating our antiquated system. If it works as advertised should do everything we need. Even has a blue tooth option for remote monitoring.

    Forgot to mention, it's the hybrid model, would post a link if I was able and if it was allowed, don't want to break forum rules.

    It looks like a typical high-frequency inverter, which more or less means no meaningful surge capacity.  It "says" 7000W surge, but for how long?  Top quality inverters rate their products as having a 60 second surge, lesser products with a 5 second surge, and low budget "cheapo" inverters with as little as a 8ms surge.  That's 8 thousands of a second!  Since they don't even specify how long a surge it can handle, I would take that as a red flag.  It will be OK for watching TV, and lights, but don't try running a circular saw.
    System 1) 15 Renogy 300w + 4 250W Astronergy panels,  Midnight 200 CC, 8 Trojan L16 bat., Schneider XW6848 NA inverter, AC-Delco 6000w gen.
    System 2) 8 YingLi 250W panels, Midnight 200CC, three 8V Rolls batteries, Schneider Conext 4024 inverter (workshop)

    So it probably is too good to be true... I need one that can run my well pump and sanitation lift pump which my present inverter does easily. It is approaching 20 years old and is used on weekends only and vacations, but I would really like to increase my battery bank voltage as well.
    I do kind of like the all in one approach also, the cost is low enough that you could buy two and have a spare. Also, at least I have heard of Renogy, some of the other hybrids not so much.

    While checking through the manual I found another concern, it states: For PV to charge 48V battery banks, you will need a minimum PV Voc voltage of 
    60VDC. It seems to me that 60 VOC is kinda low to charge a 48v battery. In my case that would be 3 series 17 volt VMP panels for 51VMP and 65.1 VOC, would that work? So this MPPT can boost and buck?

    So here's the manual;

    RIV4835CSH1S-G1【48V 3500W逆变一体机】_说明书_V1．1_20201229 (mybigcommerce.com)

    A few things caught my eye;
    Appears the max equalizing is under 60 volts, battery voltage range is also 40-60 volts.
    Many flooded lead acid batteries equalize higher than this (Rolls is 64 volts!) I use ~of 62 volts.


    I don't see a safety rating UL1741 would be for home use.



    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    It puzzles me as why a company would sell a product that will not work properly. How much harder is it to make it work in the field? Great concept poor execution. Even if it costs more, are there any hybrid inverters from Outback, Schneider or Magnum?

    Schneider  makes the XW series, which are hybrid inverters

    Perhaps 'gearing up' for a lithium battery world...sigh.

    Looks good Mike but I did not see a built in MPPT charge controller. Photowhit probably right, but our battery storage is outside in a insulated box and it has been reaching -20 degrees Fahrenheit here lately so I am a FLA user.

    Oh,   only a charger when running from genset or grid.   The solar MPPT controller is another box
