The Rich Solar MEGA 250 is a 250W 12V off-grid solar panel built for RVs, vans, boats, cabins, marine setups, DIY solar projects, and compact off-grid power systems. It is available as MEGA 250 Silver and MEGA 250 ONYX Black model options. This panel uses tempered glass, aluminum, and monocrystalline silicon in a 60.6" × 29.9" × 1.2" frame that weighs 26.9 lb. The MEGA 250 is listed with 250W maximum power, 1500VDC maximum system voltage, 0 to +5W positive power tolerance, and a 64-cell monocrystalline module design. With an IP68 junction box, IP67 connectors, and a 25-year power output warranty, the MEGA 250 is built for properly designed 12V solar systems.
The MEGA 250 gives off-grid builders a higher-output 12V panel for mobile and compact solar layouts. It is suited for RVs, vans, boats, cabins, DIY solar projects, marine applications, and off-grid systems when paired with compatible charge control, battery storage, wiring, and mounting hardware.
This Rich Solar panel is listed as a 64-cell monocrystalline module with 25.1% maximum cell efficiency and 0 to +5W positive power tolerance. These details support its role as a compact, high-output panel for buyers comparing 12V off-grid solar options.
The MEGA 250 includes an IP68-rated junction box and IP67 connectors for outdoor protection. It is listed to withstand 2400 Pa wind, 5400 Pa snow load, and hail impact up to 35 mm at 97 km/h when installed properly.
Pre-drilled holes provide mounting support for compatible brackets, racks, and frames. IP67 connectors and listed cable length support practical panel-to-panel planning when the full solar system is properly designed.

The MEGA 250 gives mobile and off-grid builders a higher-output panel for RVs, vans, boats, cabins, and marine solar layouts. Its 250W rating helps reduce the number of panels needed compared with smaller modules when the system is properly designed.
With an IP68 junction box, IP67 connectors, and pre-drilled mounting holes, this panel is built for practical outdoor installation planning. Confirm controller, battery, wiring, inverter, and mounting compatibility before installation.
