Have been running my 24v system for over 2 years now problem free while building my off grid house. Simple connection following instructions. I purchased all DC, AC etc. boxes as suggested by Schneider and assembly was straight forward. Have been running FLA batteries while building but am about to change to Lithium when we move in soon. We run planers, table saws, window AC unit, lights, fridge constantly, etc. as needed. Plan to stack a second Schneider box in about a year to allow running of welders and air compressors in my shop.
