    With the experiences I related to you with micro inverters. You might look at who is likely to help if you have problems and who has been in business the longest and perhaps if they are a branch of an electrical contractor who does other things and might be in business longer.
    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.
