Rich Solar MEGA 175 PRO 175W 24V N-Type Solar Panel

The Rich Solar MEGA 175 PRO is a near-square 175-watt panel with a higher operating voltage (Vmp 30.3V), so it charges 24V batteries directly and lets 12V systems run fewer, thinner wires to an MPPT controller. 18-busbar N-type TOPCon cells sit behind 3.2 mm AR-coated tempered glass in an anodized aluminum frame. A 20 ft MC4 extension cable set comes in the box.

Check your controller's PV voltage limit before wiring in series: two panels reach about 73V open-circuit before any cold-weather correction.
