Customers install only the solar modules on their home or business down to a DC disconnect switch or plug. Customers then contact their electric utility to install the Utility-Owned Battery and handle all of the interconnection details at no cost to the customer.
The advantage to the customer is that they get emergency back-up power for their ENTIRE home or business without any internal wiring changes, and they get paid for 100% of their solar generation.
The advantage to the electric utility is that they get to manage when the solar power is added to their grid, do not lose any revenue from net metering, and they have complete control of their battery for other grid needs as they see fit.
It is a WIN WIN for everyone!
