Hi Chris The 1.1 MCU issue might have been known but they did a horrible job with my buddy.
7 x MCU 1.1 boards 1 replacement inverter to fix a failed inverter turned out to be a warranty unit that wasnt fixed and of course didn’t work. And again this system was designed with their approval, and the loads are exactly as he told them and web connected After months they finally coped to the issue with 1.1 and got him 2 new units with 1.2 boards after trying 1.2 boards in the older units which didn’t work probably due to other damage. They are still trying to get him to pay $1500 for the inverter failure which was under warranty, it’s been 2 months and still not resolved. Total time of the project and issues 6+ months. Number of field trips 15+ Hours per trip 5+ Payment for those trips 0 While it’s been good to hear all the positive reviews here, what my buddy has gone through gives me huge concern to give them my money.
