SMA made inverters for railway cars, I suppose providing AC power for occupants from the high voltage DC powering the train.
They've made PV and battery inverters for decades. In the early 2000's, when California had rebates for solar, SMA was > 50% of all installations and 20 other brands made up the remaining < 50%. There are more viable quality competitors now, at least for GT PV.
People here have had warranty replacements, including some who bought equipment from the defunct DC Solar.
Primarily, the equipment has a low failure rate. I had one die in warranty with a blown up PCB trace, and SMA covered shipping and swapped a board. One other blew a crater in a power transistor and I took it out of service. Meant to repair some day but bought later models for 20% the original price.
They're not cheap, but definitely worth it if your loads include motor surges or if you have lead-acid batteries which they have a reputation for taking good care of. For U.S. split-phase we either need two or a transformer but you can use one. The cost is still high, and I only put in 4x because I got a liquidation (bankruptcy) deal. For a system with larger PV array and battery, inverter is just a portion of the cost.
Schneider, Outback, Midnight, some others here also have a good reputation. I just don't know about availability and support in Israel. SMA being there is a plus.
