Solar + storage inverter selection: inverter stacking vs. high voltage inverters

Solar + storage inverter selection: inverter stacking vs. high voltage inverters

December 7, 2018 at 8:00 am 1 comment

Scaling an energy storage system requires stacking both energy (batteries) and power (inverters). Batteries that were designed to be modular can typically be stacked without limitation. However, inverter stacking presents more challenges. The question installers must answer is at what point does it make sense to jump from a multi-inverterRead More
