The MEGA 150 is a 12V off-grid solar panel, sized as a single panel or scalable in pairs for larger arrays.
A pair of 12 AWG panel leads (3ft each) with MC4 connectors, terminating in an IP67-rated waterproof junction box — ready to wire into a charge controller.
Fourteen pre-drilled holes accept standard Z-brackets, tilt mounts, pole mounts, or ground mounts, so it fits most common RV, boat, and cabin mounting setups.
Yes — it's compatible with both on-grid and off-grid inverters and standard MPPT or PWM charge controllers rated for its voltage and current output.
Both options are the same MEGA 150 panel — the 2-panel option simply bundles two units together for a 300W array at checkout.
