2.0 General Information
2.1 Overview
Thank you for selecting the SunSaver MPPT charge
controller with TrakStar Technology
TM
. The SunSaver MPPT
(SS-MPPT) is an advanced maximum power point tracking
solar battery charger and load controller for stand-alone PV
systems. The controller features a smart tracking algorithm
that maximizes the energy from the solar module(s) and
also provides load control to prevent over-discharge of the
battery.
The SS-MPPT battery charging process has been
optimized for long battery life and improved system
performance. Self-diagnostics and electronic error protection
prevent damage when installation mistakes or system faults
occur. The controller also features four (4) settings switches
for adjustability, a meter port, and terminals for remote
battery temperature measurement (optional).
Using MSView
TM
PC software, the SS-MPPT can be
programmed with custom settings to function as a lighting
controller to turn the system loads on and off at specied
intervals throughout the day and night. See section 4.7 for
more information.
Although the SS-MPPT is very simple to congure and
use, please take the time to read this operator’s manual and
become familiar with the controller. This will help you make
full use of the many advantages the SS-MPPT can provide
for your PV system.
