Select a Battery Type
The SunSaver provides a Battery Select Jumper to
choose the battery type. See Section 7.0 Technical
Specications for detailed charging information for each
battery type.
The battery select jumper is secured in the terminal block
between terminal #6 and terminal #7 as shown in gure 2a.
The second column in table 1 species whether the jumper
should be removed or remain in place, depending on the
desired battery type.

Choose Regulation Method (optional)
Choose between Pulse Width Modulation (PWM) charging
or Slow Switching charging. PWM charging is the default
regulation method and is the method recommended for most
systems.
Slow Switching regulation should only be selected if noise
or interference exists in the system due to PWM charging.
This regulation method limits the switching frequency to 10
Hz (maximum), which can eliminate noise issues in some
systems.
PWM charging is selected by default. To enable Slow
Switching regulation do the following:
1. Remove all four screws that secure the faceplate on
the SunSaver. See Figure 2b.
2. Gently pry the faceplate off the SunSaver.
Occasionally, epoxy encapsulant will cause the
faceplate to stick. Use a small at-head screw driver
to separate the faceplate from the SunSaver body.
See Figure 2c.
3. A loop of wire protrudes from the epoxy. Cut the loop
with wire clippers to switch the regulation method to
Slow Switching. See Figure 2d.
4. Tape the cut ends with electrical tape to prevent
contact with the faceplate.
5. Replace the faceplate and secure with the four
screws.
