The Rich Solar MEGA 400 is a 400W solar panel built for residential, commercial, agriculture, grid-tie, and off-grid solar projects. This 24V voltage-class panel is sold in pallet quantities of 8, 10, or 12 panels, making it better suited for larger solar layouts than single-panel upgrades. Each panel uses tempered glass, aluminum, and monocrystalline silicon in the updated 67.8" × 44.7" × 1.2" frame that weighs 45.2 lb. With 400W maximum power, 31.0V maximum power voltage, 1500VDC maximum system voltage, and a 25A maximum series fuse rating, it is designed for properly engineered solar arrays. The MEGA 400 also includes approximately 47" panel cable length, listed source-copy cell technology details, and a 25-year limited power output warranty.
The MEGA 400 is designed for larger residential, commercial, agriculture, and off-grid solar layouts. Pallet quantities of 8, 10, or 12 panels support scaled project planning where matched panels, freight handling, and system design matter.
The provided source copy lists Mono PERC technology and a 10-busbar solar cell configuration. Verify these details in the linked RS-M400 / RS-M410 specification sheet before treating them as structured technical specs.
Rich Solar notes that the new 400W panels measure 67.8" × 44.7" × 1.2". This updated size should be used for racking, spacing, freight, layout, and installation planning instead of older MEGA 400 dimensions.
Mounting should be planned with compatible racking and hardware verified against the RS-M400 / RS-M410 specification sheet. Source-listed quick-connect cables can support series or parallel wiring only when voltage, current, controller or inverter limits, wire sizing, overcurrent protection, and full system design are properly matched.
The MEGA 400 is built for larger solar projects where panel count, output, and system design need to be planned together. Pallet options of 8, 10, or 12 panels support residential rooftops, commercial arrays, agriculture sites, and off-grid power layouts.
With a 1500VDC maximum system voltage, 25A maximum series fuse rating, and approximately 47" panel cable length, this panel is built for serious solar system planning. Confirm racking, inverter, controller, wiring, overcurrent protection, permitting, and site requirements before installation.
