What can this solar panel add?

Estimate how much energy this panel could put back into a compatible power station during a sunny day.

Device

Estimates vary with device power use, cycling, and conditions. Check starting-power compatibility.

How we estimate

Device presets are examples: refrigerator 75W average, router alone 15W, CPAP 40W, TV 100W, and sump pump 600W while running. CPAP heating and additional network equipment can increase usage. For a custom cycling device, enter average watts over time.

Daily solar energy assumes 3 peak-sun hours and 75% yield. This is an illustration, not guaranteed output. A compatible power station is needed to store the energy.

Energy duration does not confirm that a station can run or start a device. Check its continuous and surge ratings.

AF-SA400 vs AF-S400A1

Although both models deliver a rated output of 400W, they are built for different applications. The upgraded AF-SA400 features a rigid aluminium-frame construction, increased operating voltage, and improved heat management, making it an excellent choice for permanent outdoor installations and continuous solar charging. In comparison, the AF-S400A1 offers a lightweight foldable design that is ideal for camping, RV adventures, and users who prioritise portability.

Common Questions

Will this work with my power station?

Compatibility depends on your power station’s solar input limits, connector type, voltage range, and maximum wattage. Always confirm compatibility with your exact power station model before ordering.

How fast will it recharge?

Recharge speed depends on sunlight, weather, panel angle, panel wattage, and your power station’s solar input limit.

Is this good for off-grid use?

Yes, when paired with a compatible portable power station, it can help recharge during camping, RV use, outages, and off-grid setups.

What should I check before buying?

Check wattage, open-circuit voltage, connector type, folding design, portability, and whether the panel is compatible with your specific power station model.

Can I connect more than one panel?

Only when the complete series, parallel, or series-parallel array remains within the power station’s maximum solar voltage, current, and wattage limits. Calculate array values from each panel’s Voc, Vmp, Isc, and Imp before connecting.
