The Rich Solar MEGA 250 PRO is a 250W 24V off-grid solar panel built for campers, tiny homes, cabins, RVs, vans, marine setups, DIY solar projects, and higher-wattage off-grid systems. It is available as the MEGA 250 PRO ONYX Black under SKU RS-M250PB and the MEGA 250 PRO Silver under SKU RS-M250P. This panel uses tempered glass, aluminum, and monocrystalline silicon, with N-Type TOPCon cells and a 16-busbar design listed in the source copy. Its 60.6" × 29.9" × 1.2" frame and 26.9 lb weight match the same physical footprint as the 12V MEGA 250, while the 36.9V maximum power voltage supports 24V voltage-class system planning. With 250W maximum power, 1500VDC maximum system voltage, listed IP68 waterproof protection for the junction box / connectors, and a 25-year power output warranty, the MEGA 250 PRO is built for properly designed high-power solar layouts.
The MEGA 250 PRO gives builders a 24V voltage-class 250W panel option for campers, tiny homes, cabins, RVs, vans, boats, and off-grid solar arrays. Its higher voltage profile can help simplify properly designed systems above 12V by reducing some panel-combining requirements, depending on controller, battery, inverter, wiring, and string design.
This Rich Solar panel is listed with TOPCon N-Type cells, 16-busbar construction, and 0 to +5W positive power tolerance. The source also lists up to 25.1% maximum efficiency, low-light performance language, and a -0.35%/°C temperature coefficient.
The source describes the MEGA 250 PRO as built for harsh environments, including salt, ammonia, sand, high temperatures, and high humidity. It also lists 3.2 mm AR-coated tempered glass, an aluminum frame, IP68 waterproof protection, PID resistance, and 100% double EL inspection; verify exact test standards before presenting these as certified environmental ratings.
Pre-drilled holes allow flexible mounting options for compatible brackets, racks, and frames. MC4 connectors with source-listed pre-attached cables help simplify panel-to-panel connection work during properly planned solar installation.

The MEGA 250 PRO gives off-grid builders a 24V panel format for higher-wattage system planning. Its 250W rating, compact footprint, and rugged component set make it useful for campers, tiny homes, cabins, vans, boats, and solar arrays.
With listed IP68 waterproof protection, MC4 connectors, source-listed pre-attached cables, and support for PWM or MPPT controllers, this panel supports practical installation planning. Confirm controller, inverter, battery, wiring, and mounting compatibility before installation.
