AFERIY ‎‎AF-S400 400W Portable Foldable Solar Panel

No, it cannot. We understand your expectations for the product's performance, but it is a common phenomenon in the solar panel industry that the actual power output does not reach the rated value. The reasons are as follows:

Firstly, the rated power is measured under standard test conditions, usually tested under ideal sunlight intensity, temperature, and angle conditions (the rated power of solar panels is typically measured under standard test conditions (STC), which is power measured under conditions of 1000W/m² of light intensity, 25℃ temperature, and vertical sun angle).

However, factors such as actual installation environment, sunlight intensity, temperature, and shading can affect the power output of solar panels. These conditions may not be fully met, resulting in actual output power lower than the rated power. Therefore, under optimal conditions, the actual power output of a 400W solar panel would be around 300-320W (about 75%-80%).

To protect your portable power station and connected devices, it is recommended to ensure that the output power, voltage, and current of the solar panel are within the specifications of the AFERIY portable power station when purchasing or using it.

Yes, but it is not recommended. The AFERIY product is designed to disconnect the solar panel connection when there is no power input or insufficient energy conversion from the solar panel.

The reasons are as follows:

The AFERIY portable power station is equipped with a relay, which serves to protect the power station and connected devices from damage caused by current abnormalities such as overload and short circuit. Specifically, the relay is an electrically controlled switch device that can be opened or closed when the current or voltage reaches a set value. In portable power stations, relays are commonly used to monitor changes in current and voltage to protect the power station and connected devices.

It will consume a certain amount of power. When the AFERIY portable power station is not receiving any power input, such as when it is continuously connected to a solar panel, there will be a slight power consumption, approximately 30Wh per hour. However, if the AC switch is turned on, it will automatically shut down after 8 hours and may consume up to 20% of the power.

Therefore, it is recommended to unplug the charging plug when there is insufficient energy conversion from the solar panel, and charge when there is sufficient light and stable solar conversion.

If you must connect the solar panel when there is no sunlight at night, in order to save power consumption of your portable power station, please turn off the AC switch and other input switches.

After sunrise on the second day, it can automatically restart and resume charging.

However, please note that weak sunlight during sunrise and sunset may result in repeated charging and restarting of the product (equivalent to repeatedly plugging and unplugging the charging plug of the solar panel) and repeated activation of the internal relay of the AFERIY portable power station. It is recommended to unplug the charging plug when there is insufficient energy conversion from the solar panel and charge when there is sufficient light and stable energy conversion.

No, it is not possible to connect solar panels with different voltages and currents in series. When connecting solar panels in series or parallel, it is important to ensure that the parameters of the solar panels (such as open circuit voltage, short circuit current, etc.) are similar to avoid efficiency losses or damage to the equipment. Additionally, it is necessary to use appropriate voltage regulators or charge controllers to manage and protect the charging process of the energy storage device.

To protect your portable power station and connected devices, please follow the following recommendations: use solar panels of the same brand and with the same rated values when connecting them in series or parallel.

If you connect two solar panels with different voltages and currents in series, any damage caused to the equipment will not be covered under our warranty.

The AFERIY solar panel has undergone extensive reliability testing and has an IP65 waterproof rating. However, in order to achieve a longer lifespan in suitable environments, we do not recommend prolonged direct exposure to rainwater.

Yes, the AFERIY solar panel is compatible with most other brands of portable power stations available on the market.

However, specific compatibility depends on the interface and power specifications (output voltage, current, power) of the AFERIY solar panel and the other brand's portable power station. To ensure compatibility between the AFERIY solar panel and other brands' portable power stations, it is recommended to carefully review the product specifications and compatibility information before purchasing or contact AFERIY with the solar input interface and power specifications of the other brand's portable power station for confirmation.
