Exact revision: AS340; PS400 Bifacial Portable Solar Panel (Quick Start Guide V1)

Product identity source · checked 2026-10-09 Revision source · checked 2026-10-09

The PS400 packs a 400W nameplate rating into a folding panel that weighs 9.95kg and opens to about 90 inches long. Before making room for it, check the station’s voltage limit: the panel’s 57.6V open-circuit rating rules out inputs with a lower ceiling.

BatteryRank review

Our verdict

A high-output option for a station with solar input that can accept the panel’s 57.6V Voc and corresponding current. Its 400W STC rating and wide unfolded footprint suit buyers who can give it a clear setup area; check the receiving device’s full input limits before purchase.

Review notes

Where it fits

For higher-input portable stations

The PS400 suits a station with a larger solar input and a setup with enough open ground for its roughly 90-inch unfolded length. The rear face can add output where reflected light reaches it, but a clear front-facing area remains the reliable starting point.

What changes the decision

Tradeoffs

It takes real room to unfold

At 90.2 × 38.7 in unfolded, the PS400 needs more than a narrow strip of sun. We would reserve space for the full panel footprint and reposition it as the sun moves.

The station must accept its voltage

The technical sheet lists 57.6V Voc and 8.75A Isc. Compare those ratings with the station’s permitted solar-input voltage, current and power, then check cable polarity. The separate 75V maximum system voltage is a panel limit, not its output voltage; a fitting XT60i plug alone does not establish compatibility.

Rear-side output is conditional

Anker describes up to 10% more power from dual-sided generation. That depends on reflected light at the rear surface, so we would size around the 400W STC rating rather than count on the advertised uplift.

The water rating has a practical limit

Anker lists IP68, but its product FAQ advises against heavy rain and submersion. We would pack the panel away when severe wet weather approaches.

Before connecting

Setup and compatibility

Unfold and aim it squarely at the sun

Open the panel and brackets, then angle the face so sunlight lands as close to perpendicular as practical. The Anker guide shows this setup and advises repositioning as needed.

Connect with the included cable path

The AS340 guide lists two 2.5m PV extension cables and a 0.5m PV-connector-to-XT60i charging cable. Confirm the receiving station’s Voc, current, power, polarity, and cable requirements before making the connection.

Protect hands while adjusting the frame

Anker cautions that the aluminum-alloy frame can heat up after sun exposure. Handle it carefully or wear gloves when changing its position.

Read the exact power-station manual before pairing equipment. Our solar panel pairing guide explains the input checks, and the solar recharge deficit tool estimates whether a setup can keep pace with daily use.

Exact model questions

Frequently asked questions

What is the PS400’s electrical rating?

Anker lists 400W ±5% at STC, with 57.6V Voc, 8.75A Isc, 48V Vmp, and 8.33A Imp. Compare these ratings with the receiving station’s input ceiling before connecting.

What is included for connecting the panel?

Anker’s AS340 Quick Start Guide V1 lists two 2.5m PV extension cables and a 0.5m PV-connector-to-XT60i charging cable. The technical sheet identifies the panel connector type as MC4.

Will any power station accept the PS400?

Check the station’s permitted solar-input voltage, current, power and operating conditions against the PS400’s STC ratings. Its 57.6V open-circuit voltage is too high for an input capped below that figure. The panel’s separate 75V system-voltage limit is not an output rating. Verify connector polarity and the required cable as well.

Does the rear side guarantee extra output?

No. Anker says dual-sided generation can provide up to 10% more power, while the technical sheet names 400W as the STC maximum power. Rear-side contribution depends on reflected light reaching that surface.

Is IP68 a reason to leave it out in a storm?

Anker’s product FAQ says to avoid heavy rain and submersion despite the IP68 listing. We recommend bringing the panel inside during severe weather.
