Anker SOLIX PS400 400W Monocrystalline Solar Panel, 23% Efficiency, IP67, Ground Mount, Black/Blue

Anker SOLIX PS400 — High-Output Ground-Mount Solar for Off-Grid Power

The Anker SOLIX PS400 400W Monocrystalline Solar Panel, 23% Efficiency, IP67, Ground Mount, Black/Blue is built for anyone who needs serious solar generation in a portable, ground-level setup. Whether you are running a portable power station on a campsite or feeding energy into a home battery system, this panel delivers consistent output from a single 400-watt monocrystalline unit. Its 23% cell efficiency puts it among the top tier of folding panels, which means more energy captured per square metre of silicon. Because it is IP67-rated, you can deploy it outdoors in heavy rain without worry.

Core Numbers — The Specs That Matter

Why 23% Efficiency Changes Real-World Output

Cell efficiency is the single biggest driver of how much energy a panel produces at its size. At 23%, the PS400 converts more sunlight into usable power than most portable panels on the market. In practical terms, that means faster charging times for compatible power stations. Because monocrystalline cells degrade more slowly than polycrystalline alternatives, you also get steadier performance over years of use. For UK conditions, where daylight hours can be limited in winter, every percentage point of efficiency counts.

Adjustable Tilt From 30° to 80° — Catch the Low Winter Sun

The PS400 lets you set the panel angle anywhere between 30° and 80°. This matters because the sun sits much lower in the sky during British autumn and winter. By steepening the tilt angle, you can maintain a more direct angle of incidence and keep output higher when it matters most. In summer, you can flatten it out to match the overhead sun. The adjustment mechanism is straightforward and tool-free, so repositioning throughout the day takes seconds.

IP67 Weather Protection for All-Season Deployment

An IP67 rating means the panel is fully sealed against dust and can withstand immersion in water up to one metre deep. In everyday UK use, this translates to complete confidence during downpours, frost, and muddy ground conditions. You do not need to rush out and cover the panel when a storm rolls in. The robust build quality also helps protect the internal cell connections from vibration during transport.

Stackable Design for Flexible Setups

This panel is designed to stack with other units, which makes it straightforward to build a larger array as your energy needs grow. Start with a single PS400 and add more later without replacing your existing kit. The stackable form factor also simplifies storage. When folded and stacked, the panels take up less boot space, which is a practical benefit for campervan and overlanding use.

Black and Blue Finish With Ground-Level Mounting

The black and blue colour scheme is not just cosmetic. The dark cell surface maximises light absorption, while the blue backing helps with heat dissipation. Ground-level mounting keeps the panel stable in wind, especially when paired with the adjustable tilt stand. There is no need for roof racks or permanent fixtures, which makes this a strong option for renters, allotment holders, and anyone who wants a non-permanent solar installation.

Before You Order — Quick Compatibility Check

• Confirm your power station accepts solar input of at least 400 W via MC4 or a compatible adapter.
• Check the panel’s connector type matches your existing cables or charge controller.
• Measure your available ground space to ensure the panel fits at your preferred tilt angle.
• Verify your location gets sufficient direct sunlight during the hours you plan to generate.

Frequently Asked Questions

Q: How much power can the PS400 generate on a typical UK day?

A: Output depends on sunlight conditions, panel angle, and shading. Expect roughly 1.5 to 2.5 kWh on a clear summer day in southern England.

Q: Is this panel compatible with Anker SOLIX power stations?

A: Yes, the PS400 is designed to work with Anker SOLIX portable power stations using standard MC4 connectors and compatible adapters.

Q: Can I leave the panel outside permanently?

A: The IP67 rating protects against rain and dust. However, long-term UV exposure and extreme weather may shorten its lifespan, so storing it when not in use is advisable.

Q: Does the panel work on cloudy days?

A: Yes, monocrystalline cells still generate power in diffused light. Output will be lower than in direct sunshine, but charging does continue.

Q: How many PS400 panels can I stack together?

A: The panels are designed for stacking. Check your charge controller’s maximum input voltage and current to determine how many units you can safely connect.

Q: What is the tilt adjustment mechanism?

A: The integrated stand allows smooth angle changes between 30° and 80°. No tools are required to adjust the tilt position.

Our Verdict

The Anker SOLIX PS400 suits anyone who needs reliable, high-wattage solar in a ground-mount format. Its 23% efficiency and adjustable tilt make it particularly well suited to UK conditions. If you already own a compatible power station, this panel offers a strong path to energy independence outdoors. Warranty cover varies by product, so please contact us to confirm.
