Chapter 1 SunStar Description
The SunStar is a technically advanced solar system controller. There are three operating
modes programmed into each SunStar. The manual describes solar battery charging, DC
diversion charge control or DC Load control instructions are inserted where required.
The manual will help you to become familiar with the SunStar’s features and capabilities.
This operation manual is applicable to the software version V1.05 and later version of the
SunStar units. Some of these follow:
z
Solid-state Pulse Width Modulated (PWM) charging process with four-stage control,
temperature compensation, and manual or automatic equalization to maximizes system
performance and increase battery life.
z
Electric overload and short circuit protection with automatic and manual reset
capability increase the reliability of unattended systems by eliminating blown fuses
and tripped circuit breakers.
z
Optional external battery temperature compensation (BTS) for automatic adjustment of
charge setpoints.
z
Over-temperature protection for the electronic circuitry when used in hot environment
(over 80
℃
)
z
LCD meter with easy to read mode/status messages.
z
LCD meter for remote or direct mounting on the controller. May be mounted up to 500
feet away.
z
An 8-position DIP switch to set up the controller for its intended use. All major
functions can be set with DIP switches.
z
Rated for 12, 24, 48 volt systems, and 30, 45 or 60 amps current.
z
Eight standard charging or Load programs selected with DIP switches.
z
Continuous self-testing with fault notification.
z
LED indications and pushbutton functions.
z
Complies with EMC and LVD standards for CE marking.
