Operating Modes; Adjustability - Invertek SUNSTAR SERIES Installation And Operation Manual

1.2 Operating Modes

There are three distinct and independent operating modes programmed into each SunStar.
Only one mode of operation can be selected for an individual SunStar. If a system requires a
charging controller and a load controller, two SunStars must be used.
Solar Battery Charging
The energy output of a solar array is used for recharging the system battery.
The SunStar manages the charging process to be efficient and to maximize the life of the
battery. Charging includes a bulk charging stage, PWM absorption, float and equalization.
DC Load Control
When set for DC load control, the SunStar powers loads from the battery, and protects the
battery from over-discharge with a current compensated LVD (low voltage load
disconnect).
DC Diversion Charge Control
In DC diversion mode, the SunStar will manage battery charging by diverting energy from
the battery to a dedicated diversion load. The energy source is typically wind or hydro.
