Used for 8 months continuous service. Kept indoors in my shop. Was used in a AC coupled set up, but have now switched to high voltage controller so no longer need. Has 3 channels of MPPT tracking to allow for up to 3 solar panel arrays. Will produce 110V in 2 leads to your panel allowing you to have 220V for your use. Works well in AC coupled without direct communication with battery inverters, as long as the battery inverters are slightly higher wattage than 7000w. Otherwise, if you are wanting to build your own grid tie solar, this is a great product. SMA is the best in the business. Equiipped with a wifi for linkage to your smartphone or laptop for configuration. Comes with all manuals, mounting bracket. Intended for US only.
