The EcoFlow In-Series Solar Connection Cable (XT60) is a short 17 cm adapter that connects two portable solar panels with a built-in XT60 output in series before feeding them into a single XT60 input on a power station. It weighs just 40 g and adds no significant bulk to the setup. Series wiring adds the voltages together while keeping the current the same, which is useful for reaching the higher MPP window of a large power station without needing multiple inputs.

• Compact 17 cm cable that combines two XT60 panels into a single XT60 lead, ready to plug into a power station.
• Especially useful for the 110 W, 160 W, 220 W and 400 W lightweight bifacial foldable solar panels with a built-in XT60 connector.
• Series wiring adds the open circuit voltages of both panels together — always check that the sum stays under the maximum input voltage of the power station.
• Two matching panels (same model and wattage) should always be used together — do not mix different panels on the same series cable.
• Very light at only 40 g, so it stays out of the way in the panel bag.

A practical solution for boosting solar input on a large portable power station in a single-input configuration, provided the combined panel voltage stays inside the station's rated PV window.
