Modular energy portal with AC architecture for harvesting energy from electrical power sources

摘要

A modular energy harvesting portal including a housing with a bay, a plurality of inverters, a controller, and an AC bus. A first inverter has a first DC input, a first AC output, and a first power rating. The first inverter converts DC power to AC power and outputs the AC power to an AC bus. A second inverter has a second DC input, a second AC output, and a second power rating. The second inverter converts DC power to AC power and outputs the AC power to the AC bus. The inverters are positioned in the bay. The controller selectively controls a switch to couple the AC bus to an AC grid. The modular energy harvesting portal system has a power rating dependent on the number of inverters and the power rating of each of the inverters.
