DOKIO 800W Solar Panel 2-Pack 400W 31V

This DOKIO set pairs two 400W monocrystalline solar panels for a combined 800W (STC) output, built with tempered glass, an aluminum frame, and sealed IP65-rated junction boxes for year-round backyard use. Each panel delivers 31V output and works with 12V and 24V systems, including AGM, Gel, and LiFePO₄ batteries via PWM or MPPT controllers, and MC4 adapters connect to many portable power stations.

Using two 400W panels instead of eight 100W panels means far fewer splitters and joints, reducing failure points and keeping the array cleaner. Parallel wiring is the default for 12V to keep voltage safe and charging steady, while series wiring should only be used with suitable controllers; select a controller or inverter that handles the total current, with MPPT advised.

Key Features

Highlights

• [OUTDOOR-READY] Tempered glass and aluminum frame with sealed junction boxes for backyard year-round use.
• [WORKS WITH 24V BANKS] Compatible with AGM/Gel/LiFePO₄ via PWM/MPPT; MC4 adapters connect to many portable power stations.
• [FEWER CONNECTIONS VS 8×100W] Many fewer splitters/joints than eight 100W panels—fewer failure points and a cleaner array.
• [12V PARALLEL FIRST] Parallel wiring is the default for 12 V to keep voltage safe and charging steady; series only with suitable controllers.
• [DOUBLE THE POWER] A pair of 400W panels provides 800W (STC)—select a controller/inverter that handles the total current; MPPT is advised.
