EcoFlow PowerStream / STREAM 800W Balcony Solar + 2kWh LFP Kit — California ROI & Legal Compliance Calculator

SB 868 passed the California Legislature in August 2026 to legalize up to 1,200W plug-in solar systems on standard 120V outlets without utility interconnection fees (effective Jan 1, 2027 upon enactment). Under NEM 3.0, combining plug-in solar with a 1.6kWh–2kWh LFP battery avoids exporting at 8¢/kWh and offsets 58¢/kWh evening peak power.
