Common Questions
Can this panel be used in a grid-tie system?
Yes — the MEGA 400 is compatible with both grid-tie and off-grid inverters, making it suitable for utility-connected residential and commercial installations as well as fully off-grid setups.
How is this different from Rich Solar’s smaller RV-focused panels?
At 400W and 45.2 lbs, the MEGA 400 is built for fixed residential, commercial, and agricultural installations rather than mobile use — larger, heavier, and sold in bulk pallet quantities rather than as single units.
What quantities does this come in?
It’s sold in pallets of 8, 10, 12, or 36 panels. For other quantities, Rich Solar’s sales team can be reached directly by phone or email.
What’s the actual usable lifespan?
It carries a 25-year limited power output warranty plus a 10-year workmanship warranty, in line with Rich Solar’s other MEGA Series panels.
Do I need a licensed installer for a system this size?
Given the scale and voltage involved in residential, commercial, or agricultural installations — especially grid-tie systems — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
