Models: ARF-FWP-80M, ARF-FWP-100M, ARF-FWP-120M
Charging of your battery will be regulated by a waterproof,
high-efficiency MPPT solar charge controller - mounted on
the back of the solar kit. This controller constantly measures
your battery’s state of charge in order to select the most
appropriate charging parameters (voltage, current and
charging program). The Maximum Power Point Tracking
(MPPT) functionality offers increased efficiency compared to
standard PWM charge controllers, and ensures that the
solar panel provides as much power as possible. The
controller also provides the following important protection
functions for your battery:
-
Overcharge
protection
- one of the most important
functions of the controller. When your battery is full, the
controller will either switch to a trickle-charging mode
where it will continue to gently top-up the battery, or it
will stop the charging completely.
-
Reverse current
protection
- stops the power flow
from the battery into the solar panel at night.
-
Reverse polarity
protection
- if you accidentally
connect the kit to the battery using the wrong polarity,
your system is safe.
-
Load protection
– if you have connected a 12V load to
the controller (optional), the controller will be protected
from short circuits, excessive current and overheating.
In addition, the charge controller has a temperature sensor
which measures the ambient temperature. To regulate the
speed of chemical reaction inside the battery, the controller
will choose a slightly higher charging voltage in low ambient
temperatures, and a lower voltage in high temperatures.
