SBIR phase II Whole House Multi-Port Inverter

Mission Power has designed a whole-house multi-port inverter allowing connection of multiple renewal devices for the whole house. It provides a DC connection for any DC device to directly connect. This device will be built and demonstrated in the laboratory in the phase II program. Currently, almost every new solar installation, battery, wind turbine, or vehicle charger is a separate device with separate user interfaces and separate electrical requirements for connection. Power electronics are now inexpensive enough to build this whole-house system as a standard unit for both new homes and retrofits to ease the transition to solar power and all electrical devices. The inverter will be rated for 200A, 240V (48kW) ľ the full rated power for almost every home meaning it will not have to be updated when new renewable items are added. It will be designed to connect to 40kW of solar through separate Maximum Power Point Trackers (MPPT)s. Additionally, it will allow up to 48kW battery connection, multiple wind turbines, and include a bi-directional car charging port. All these devices will be connected to this single 48kW inverter. Mission Power has an experienced management and technical team that is well suited to bringing this product into production. The team includes serious technical personnel well skilled in magnetic design, power electronics design, and simulation. Further, the team includes experienced manufacturing and business personnel motivated to get the product to production quickly. Mission Power is experienced with the SBIR program and received five DOE SBIR phase I awards in 2022 & 2023. In 2023, Mission Power was awarded a $1.2M DOE incubator award for the development of a utility scale solar inverter. This was spun out into sister company Mission Sun that is performing this award. This program will leverage learning from all these programs to maximize the performance and minimize the cost of the system.
