    Hello Bill,

    I came across some of your great comments on the Wind&Sun forum and I raise my hat to your wealth of knowledge when it comes to solar systems. Kudos!!!

    I'm an electrical engineer and have been looking a solar for a few years now. But I have not yet made the jump and bought solar equipment. I'm now putting together an Off-grid solar system for a family member who is a senior citizen so I'm going with as reliable components as possible, especially when it come to the power electronics. I don’t want this person’s solar install to constantly have issues because the equipment is of poor quality.

    Here are the specs that I came up with after testing with a  Kill-a-Watt power meter.

    ·        Location: Caribbean

    ·        1800 W of solar panels (1800W * 0.77 panel+controller derating/28 volts charging lithium = 49.5A charging. Should be perfect for the 240Ah lithium bank used at 80% DoD)

    ·        Morningstar Charge controller 60A

    ·        3500-4000W inverter (brand TBD)

    ·        Batteries (I’m well versed in that)

    ·        Rest of the system (I’m good with that too)

     Location irradiance:

    Measured in kWh/m2/day onto a solar panel set at a 72° angle:
    (For best year-round performance)

    Questions:

    1) Would this forum have a section(s) that discusses recommended inverters?  (know hardware issues, support, etc…)

    2) I'm looking for feedback on quality, post-sale service, support etc... for the candidates below:

    ·        Magnum used to have a good reputation when it came to robustness and customer service. However I have seen a lot of respectable Youtubers complain about Magnums customer service ever since they've been acquired by Sensata Power. Some have documented the total lack of support by Sensata customer service.

    ·        Schneider: I have also come across a number of comments on the Schneider Inverters. The main issue with them seems to be stacking a number of units when trying to increase power. Apparently this was an afterthought and that does not really work well. Any thoughts on your side?

    ·        Other possible candidate would be Victron and Samlex Evo. Your advice on these (and any forum posts) would be very much appreciated.

     Thanks again

    Seb

    Hello!

    In one of your posts you refer to the Schneider Conext SW series issues. Would there be a specific forum post location pertaining  to the SW issues? I shoping for an 3000-4000W inverter but it seems like Magnum since they've been acquired by Sensata, their customer service and quality has degraded severely.
     
    Also would you have any personal inverter recommandations?

    Thanks
