FOSSiBOT F800 Portable Power Station | 800W 512Wh

1. It cannot. Please use the same parameters of solar panels to charge the power station. It must be same wattage and same voltage.
2. Mixing two different voltage solar panels would cause the high voltage to flow back to the low voltage, which will damage the circuit and cause damage to the solar panels and power station.

It depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use MC4 connectors and their combined voltage and current are within 12-50 volts and under 8A.
PV input requirements for F800:
Work Voltage: 12-50V
Current: under 8A
Include MC4 connectors.
Input Power: 200W Max.

By 400W AC charge: 1.5Hours

FOSSiBOT F800 Portable Power Station enables fast charging. By AC+ solar panel charge, it can be fully recharged in 1.2 hours.

4.5Hours.

A: No.

With EV-grade LiFePO4 batteries inside, F800 has more than 3500 cycles until 80%. This makes it the most durable portable power station on the market. If you charge one cycle a day, the batteries will last more than a decade.

Not, F800 is a single unit.

Use & Charge: 0-40�?(32-104�?;
Discharge: -15-40�?(-4-104�?;
Storage: -15-40�?(-4-104�?.
It performs best if you can keep it between 68°F to 86°F (20°C to 30°C).
Technically, it can power electrical devices under 0�? but please avoid charging it.

F800 supports 800W high power, it can power for 99% of your daily use appliances. F800 should work if the load doesn't exceed its rated 800W. When the load power reaches 840W, the machine will activate protection immediately.

Working time = F800's Watt-Hours * 0.85 / operating power of your device.  Example: Let's assume your device's power consumption is 400W (might be a projector), and you want to use the F800 to run your device. 512Wh*0.85/400w = Roughly 1.08 hours, the screen will show 65 mins. The screen shows actual minute when it is below 100minutes. Above 100mins below 2.5 hours will show 2 hours. Above 2.5 Hours will show 3 hours. The data is theretical lab data. Please note the actual power consumption varies based on many factors.

No. If the battery pack is faulty or even dead, please contact Customer Service.

A: When you received the machine, please recharge it to 100% battery. Then each time you use the machine, long press the main power button on top right for 3 seconds to turn on the F800. When you connect your appliances or devices to the machine, press the related on/off button. If you don't use it, press the on/off button to turn off the AC/DC/USB power, otherwise it will consume the battery.

1) Press and hold the AC button for 3 seconds to enter the frequency switching mode, the 50Hz or 60Hz icon will flash on the display, short press the AC button again to select 50Hz or 60Hz; when the icon stops flashing and displays 50Hz or 60Hz, it indicates the switch is successful.
2) Quickly press the AC button for 10 times to switch voltage between 220V and 230V.

Yes it utilizes MPPT. For those who aren't familiar with MPPT, it makes adjustments according to the fluctuating voltage of your solar panels. This results in more solar power going into your battery, even in suboptimal conditions.

F800 will auto-adjust for both 50Hz and 60Hz. You can also manually switch the output frequency on the device.

FOSSiBOT F800 has 2 versions in 2 voltage ranges:
100-120V: US/Japan
220-240V: EU

Yes, the FOSSiBOT F800 can be recharged while in use.

F800 has fans to keep its batteries cool, which run at a volume of around 50dB at 1 meter. It depends on how many watts are going in or out of the battery as well as the temperature.
