About This [800W CAPACITY] Two 400W panels deliver 800W (STC)—size your controller/inverter for the combined current; MPPT strongly recommended. [PARALLEL FIRST ON 12V] Prioritize parallel on 12 V for safer voltage and steadier charging; series only when your controller supports higher input voltage. [3 m LEADS PER PANEL] 3 m MC4 leads on each panel enable longer reaches without immediate extensions—fewer added connectors, simpler runs. [LESS HARDWARE THAN 8×100W] Compared with eight 100W panels, you’ll have far fewer joints/branch connectors, reducing failure points and time on the roof. [BUILT FOR OUTDOORS] Tempered glass + aluminum frame with sealed junction boxes for year-round yard/garden installations. [12/24V COMPATIBILITY] Works with AGM/Gel/LiFePO₄ banks via PWM/MPPT; also connects to many power stations via MC4 adapters. [DAMAGED ON ARRIVAL?] Please check the package at delivery.
