FAQ
For example, the F1200/F800 supports up to 200W DC input, while the F2400/F1800 supports up to 500W DC input. Therefore, when connected to these models, the actual charging power will be limited by the power station’s maximum DC input capacity.
The same principle also applies when charging third-party brand power stations. If the third-party power station’s maximum DC input power is lower than 580W, the actual charging power will also be limited by that power station’s input specifications.
A: A traditional 12V cigarette lighter port provides a maximum output of 100W (200W for 24V systems), while the F580 delivers up to 580W of output power �?6 times faster vehicle charging.
A: Suitable for all fuel-powered vehicles equipped with 12V/24V starter batteries, including:
�?RVs / Campervans
�?Commercial vans
�?Trucks and construction vehicles
A: Compatible with hybrid vehicles (must have an alternator and starter battery).
Not compatible with pure electric vehicles due to different power system architectures.
A: The FAC580 automatically shuts off when the battery voltage drops below 12.5V (or 12V), preventing battery drain. No manual shutdown is required.
A: The dual-voltage mode (12.0V / 12.5V) helps protect the battery. With proper use, it won’t cause measurable lifespan reduction.
A: The impact is negligible �?it uses the alternator’s surplus power (<0.5L/100km under typical conditions).
�?Make sure the vehicle is turned off before installation.
�?Perform a test fit to confirm functionality before final installation.
�?Operate only one terminal (positive or negative) at a time to �?avoid short circuits or shock.
Wear protective gear such as gloves and safety goggles.
�?Professional installation is recommended for optimal safety.
�?Required: Wrench (for battery terminal bolts)
�?Optional: Drill + wooden board (if installing in the trunk)
�?Included: Hex screwdriver (for cable connection)
�?Note: Leave at least 10cm of clearance for cooling airflow.
A: Installation position is flexible �?just ensure proper ventilation for the cooling fan.
A: Yes.
Simple installation with detailed instructional videos provided.
The most complex step (routing cable from engine bay to trunk) is demonstrated step-by-step.
A: The standard package includes a 5-meter 6AWG cable. Using the original cable is recommended.
If using your own, ensure cable reliability and proper gauge.
�?After stopping the vehicle, check the following:
Are positive and negative connections correct?
�?Are cable terminals firmly secured?
�?Restart the engine and observe the indicator light.
�?Keep the engine running to charge the car battery.
If the issue persists, contact technical support.
A: Compatible with all FOSSiBOT models and third-party devices that feature MC4 solar input ports (charging rate may vary).
Ensure the third-party device supports up to 50V input voltage.
