Notes:
▪ The "I panel" value varies depending on the type of solar panel
installed. Refer to the vendor's specifications for the solar panel
being used.
▪
The FB100 can accept a maximum of about 1 Amp, limited by its
charging circuit. Therefore, it is not practical to install a solar array
that supplies significantly more than 1 Amp to the FB100. The
maximum input is 28 volts.
Do not allow the batteries to fully discharge. Either keep providing input
power or turn the device off. If the batteries fully discharge, the battery
charger board may enter thermal limiting, which prevents the batteries
from overheating but restricts input power.
Batteries provide power for the FB100 when the solar panels are not
generating sufficient output. The batteries are three D-size lead-acid
batteries providing 2.5 Amp-hours of current at 6.2 volts.
The batteries are connected in series by the Battery Charger module to
achieve the required capacity. The amount of battery capacity
determines the number of days of reserve (autonomy) desired.
When you configure the FB100 as an API compliant Electric Flow
Management (EFM) and require an internal communications card, a
solar panel, and the internal batteries, the FB100 should be able to
communicate the API audit trail information once a day to a remote host
using no additional battery source, no additional solar panel, and
maintain a 13 day autonomy in the event that the solar panel is lost.

board to provide proper charging circuitry. Use only batteries
supplied by Remote Automation Solutions in an FB100.

Overcharging Potential

If you connect the FB103 or FB104 in one of the following ways, it is
possible to overcharge the internal power batteries:
▪ External constant power (battery, battery farm, or a constant DC
source) wired to the CHG terminals with the internal batteries
installed (FB103C1/FB104C1)
▪ External solar power panel generating greater than 5 Watts
(FB103C1/FB104C1)
▪ External power source (solar or DC) wired into the TB1 terminal
located on the battery terminal board (FB103C1/FB104C1)
