DOKIO 400W Monocrystalline Solar Panel with 31V Voltage, Designed for Charging 12/24V Devices - 3 m Cable, Ideal for Yard/Garden, Shed/Patio/Greenhouse Power, Off-Grid Battery Charging
Key features
- •[REAL-WORLD POWER] Rated 400W at STC; actual output varies with sun angle, temperature, shading, cable runs, and controller—MPPT helps keep charging steadier.
- •[3 m MC4 CABLE—LONGER REACH] 3 m (9.84 ft) leads give more routing freedom than short-lead panels, often reducing extra extensions and joints. Cleaner runs, fewer weak links.
- •[12V: USE PARALLEL] For most 12 V systems, parallel wiring delivers more stable performance; use series only if your controller explicitly supports higher input voltage.
- •[FEWER JOINTS VS 4×100W] One 400W panel replaces four 100W units—fewer branch pieces and connections, faster install, less risk of power loss from bad joints.
- •[OUTDOOR-READY BUILD] Tempered glass and aluminum frame with a sealed junction box—designed for rain and splashes in yard/garden applications.
