• Double-check that all cables are firmly plugged in.
• Avoid getting plugs and ports wet to prevent any potential damage.

5.1 Wall Outlet
Simply plug the B210 into a standard wall outlet to start charging. It typically takes about 4.8-5.3 hours for a full charge at an ambient temperature of 25°C (77°F), and the charging automatically stops once the battery is fully topped up. 5.2 Solar Panel(s)
Connect the solar panel(s) to B210 via the solar charging cable. With a continuous nput of 500W, B210 will automatically stop charging in 4.5-5 hours. However, please note that the charging time may vary based on weather conditions, sunlight intensity, panel
orientation, and other variables.
Note: Make sure your solar panel(s) meet the following requirements:
Voe: 11V-60V Current: 10A Max. Power: 500W Max.

Notice:

• If you unplug the solar charging cable from the B210 and you’re not using any DC outputs, the B210 will automatically shut down after about 4 hours.
  For solar panel(s) with an open circuit voltage between GOV and 145V, you can still use them to charge the B210. Simply connect the solar panel(s) to the 8210 via the PV Voltage Regulator, and you can enjoy seamless and hassle-free solar charging.
