Green LED: will be on or blinking when battery has been connected
On: one of the two conventional algorithms
Blinking: Battery-Life algorithms
Yellow LED: signals charge sequence
Off: no power from PV array (or PV array connected with reverse polarity)
Blinking fast: bulk charge (battery in partially charged state)
Blinking slow: absorption charged (battery charge to 80% or more)
On: float charge (battery fully charged)
Cable connection sequence (see figure 3)
First: connect the cables to the load, but ensure that all loads are switched off.
Second: connect the battery (this will allow the controller to recognize system voltage).
Third: connect the solar array (when connect with reverse polarity, the controller will heat up but will not charge the battery).
The system is now ready for use.
