MEGA 250 Pro Onyx – 250W 24V Black Solar Panel
SKU:RS-M250PB
Product Information
250W 24V Solar Panel for Cabins, Tiny Homes and 24V and 48V Systems
The MEGA 250 Pro Onyx produces roughly 1000–1250Wh on a clear day. That is enough to keep lights, a fridge, water pump and device charging going in cabins, tiny homes and 24V and 48V systems.
At 36.9V nominal it suits 24V and 48V battery banks through an MPPT controller, losing less power over long cable runs than a 12V panel. Wire several in series to raise array voltage within your controller's input limit.
Anodized aluminum frame – lightweight, strong, and corrosion-resistant. MC4 connectors with 4 ft pre-attached cables for quick and easy installation. It takes standard Z-brackets on a flat roof, or a tilt mount to angle it toward winter sun. The panel measures 60.6 x 29.9 x 1.2 in and weighs 26.9 lb.
