Our Shift home solar batteries have 5kW of power and 9.6-9.7kWh of storage capacity. For additional details, contact your Sunrun representative.

NEM 3 is a new rooftop solar export rate paradigm in California (effective as of mid-April 2023) for PG&E, SCE, and SDG&E customers. In simple terms, it reduces the compensation (in the form of net metering credits) that solar customers get for exporting excess energy to the electric grid. The precise value of this compensation varies with grid demand based on time, day, and month– but is on average approximately 75% lower than it was for NEM 2 systems. The Shift home solar battery helps counteract this by storing your excess energy rather than having it go straight to the grid, and enabling you to use it later to maximize the value of that energy.

In Hawaii, there is Smart Export rather than net metering – which means that unused solar energy exported to the grid by homeowners also receives lower compensation value (losing 25-65% of retail value depending on Island and time of export). Shift similarly counteracts this and boosts the value of solar in Hawaii by storing unused energy produced by your panels, which enables your home to use that energy later rather than it being sent straight to the grid.

There are a couple key differences compared to a standard solar battery system– the main one being that Shift does not provide home backup during a power outage. To unlock backup through outages, enable your solar panels to continue to produce power while the grid is down, and more– we recommend our backup battery options.
