EcoFlow 400 W rigid solar panels - set of 2 (800 W), monocrystalline, IP68, 172.2 x 113.4 x 3.5 cm
- Two rigid monocrystalline EcoFlow 400 W solar panels (800 W in total), 23% efficiency, IP68, Voc 37.10 V, Isc 13.79 A. Panel 172.2 x 113.4 x 3.5 cm, approx. 21.8 kg.
A set of two rigid EcoFlow 400 W solar panels with a total of 800 W. The panels use monocrystalline cells with 23% efficiency, an aluminium frame and IP68 protection. They suit off-grid and grid-tied systems, including motorhome or cabin roofs.

Two 400 W panels
- rated power: 400 W per panel, 800 W per set
- monocrystalline cells, 23% efficiency
- Voc 37.10 V, Isc 13.79 A
- IP68 protection, aluminium frame
- panel dimensions 172.2 x 113.4 x 3.5 cm, weight approx. 21.8 kg

Set contents
- 2 rigid solar panels 400 W
- user manual and warranty card
Mounting brackets, feet and extension cables are not included.
Connection
Each panel has a 3-part junction box with 4 mm² wires and a solar connector. The panels can be connected in series or in parallel - the manufacturer recommends series connection. Only connect panels with the same specifications. EcoFlow portable power stations with an XT60 input need a separate cable (not included).
Mounting
- 12 mounting holes 14 x 9 mm in the frame - do not drill or modify the frame
- a tilt angle of at least 10° reduces dust build-up
- at least 20 mm between panels and at least 40 mm between the frame and the mounting surface
- when properly mounted the panel withstands a wind load of 2400 Pa and a snow load of 5400 Pa

On a motorhome roof
On a motorhome roof the panel usually lies flat; the manufacturer states a power loss of about 5-15% compared with facing the sun directly.

Panel design
- monocrystalline cells in a black aluminium frame
- 12 mounting holes in the frame
- junction box with 4 mm² wires

Questions and answers
What is the total power of the set?
800 W - the set contains two 400 W panels.
How do I connect the two panels?
In series or in parallel - the manufacturer recommends series connection. In series the open circuit voltage is approx. 74.2 V, in parallel the short circuit current is approx. 27.6 A. Check the input limits of your charge controller or power station.
Is a cable to a power station included?
No. EcoFlow power stations with an XT60 input need a separate solar-to-XT60 cable.
How much does a panel deliver in practice?
According to the manufacturer, on a sunny day (800-900 W/m², panel at approx. 50°C) one panel typically delivers 320-350 W.
Who should install the panels?
The manufacturer recommends installation by a qualified solar installation company.
