FAQ
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.
