I am interested in buying a broken or failed P030A Fusion Box. I am planning to fabricate or upgrade the Fusion Box to manage 50 A currents (it only handles 30 A) for the AC500 5 kW controllers. Bluetti and Indiegogo offer the 30 A Fusion Box for the Split Phase 240 VAC setup which limits the output to 7.2 kW for two AC500 units, yet they promise a 10 kW setup. I wish to do this so I can setup my own 10 kW system in the future. If I am successful, I can offer the upgrade to other AC500 owners.
