POWER YOU CAN EXPECT 400W is the lab rating (STC); real-world output depends on sunlight heat shade cable length/gauge and the controller—MPPT recommended.
LONGER BUILT-IN LEADS 3 m (9.84 ft) MC4 leads reach farther than many short-lead panels often eliminating add-on extensions and extra connectors. Fewer joints = fewer issues.
12V: PARALLEL PRIORITY For 12 V systems choose parallel wiring for smoother charging; use series only with high-input controllers.
REPLACES 4×100W One 400W unit means less hardware to buy and wire fewer branch pieces and fewer chances of a poor connection.
WEATHER-RESISTANT CONSTRUCTION Tempered glass panel and aluminum frame with a sealed junction box—made for outdoor rain/splashes in yard settings.
MOUNTING FRIENDLY Pre-drilled holes align with common Z-brackets rails and tilt mounts for sheds and greenhouses.
