Battery levels, shutoff and resuming of operations

You can check the charge status of the batteries from page "ENERGY" 2.1.2. In this page you can see the current level of charge, as well as the "actions" that the robot will take, based on the voltage of the battery pack.

If the batteries discharged during the night, the FD20 is capable of resuming the operations autonomously, once the solar panels have provided enough energy to recharge them. However, there is one exception: if the batteries drops below the shutoff level, then the robot would have to be restarted manually.

The FD20 has been equipped with two different types of batteries:

• Until model year 2020, they have been equipped with 4 pcs. AGM batteries
• From model year 2021, they have been equipped with 2 pcs. Lithium batteries

To understand when the robot stops, shutoff or resume autonomously its operations, there are 4 battery levels to consider:

 

• FULL CHARGE LEVEL (28V Lithium, 26V AGM) - the battery of the robot has reached its maximum capacity and cannot absorb further energy
  
  
• IDLE LEVEL (24V Lithium, 22.5V AGM) - 10 minutes after reaching the robot stops the autonomous operation, but the basic components are still turned on. This allow the robot to resume autonomously the operations in the morning
  
  
• SHUTOFF LEVEL (23V Lithium, 21V AGM) - the robot shuts off completely and must be restarted manually in the field, once the batteries are charged again. This is a safety measure to extend the life of the battery pack
  
  
• RESUMING LEVEL (26V Lithium, 24.5V AGM) - 30 minutes after STABLY reaching this level, the droid will start again the autonomous operations, ONLY IF the battery did not drop to the SHUTOFF LEVEL during the night. If the batteries reached the SHUTOFF LEVEL, the robot WILL NOT start again in the morning, as all the systems have been shut off.
