Dependable Backup Power Wherever Life Takes You

The Grid Doctor 300 is one of the most compact and capable solar generators available.

It delivers 300 Watts of quiet, clean power wherever and whenever you need it most. It’s built on ultra-safe Lithium Iron Phosphate battery (LiFePO₄), and a full suite of power ports—including USB-C PD, AC, DC, and a car port.
