The SunSaver-10L charge controller has two topology
generations: Gen 2 and Gen 3.
Both the SunSaver Gen 2 and SunSaver Gen 3 solar controllers
ship with a jumper installed. This sets the controller for charging:
l
The sealed valve, a regulated lead acid (VRLA)
l
The absorbent glass mat (AGM) batteries, used by the solar
power system
See Figure 100 below and Figure 101 – page 85.
SunSaver Gen 2
The Figure 100 depicts the SunSaver Gen 2 solar controller.

Green LED
The green LED indicator illuminates whenever sunlight is
available for battery charging and turns off at night. Because the
SunSaver uses a PWM constant voltage charging process, there is
usually some amount of energy going into the battery at any
given time. Although the charging current falls to very low levels
when the battery reaches full charge, the green LED remains
illuminated during the daytime, indicating that the controller is
working, and energy is available from the solar panel for
charging.
