BATTERY STATUS LEDS
The Battery Status LEDs (Fig. 2 ref. (5) ) indicate the level
of charge on the battery. The indication is based only on bat-
tery voltage setpoints, which provides an approximation of
the actual state of charge of the battery.

STATUS LED
The Status LED (Fig. 2 ref. (1) ) indicates charging status
and any existing solar input error conditions. The Status LED
is on when charging during the day and off at night. The Sta-
tus LED will flash red whenever an error condition(s) exists.

TROUBLESHOOTING
Note:
A solid red Status LED indicates that a critical fault has
been detected. Critical faults typically indicate that the
controller is damaged and requires service.
LED error indications can be interpreted as follows:
“R - G sequencing” means that the Red LED is on, then
the Green LED is on, then Red LED is on....
“R&G - Y sequencing” means that both the Red LED and
Green LED are on, then just the Yellow LED is on, then
Red and Green LED are on....
Solar Overload
If the solar current exceeds the maximum solar rating, the
controller will stop charging until the solar current returns
to within its operational rating.
High Voltage Disconnect
The battery voltage has exceeded the controller’s maxi-
mum regulation limit of 30.6V . The solar and load will be
disconnected until the battery voltage decreases to the
reconnect threshold of 28V.
High Temperature Disconnect
The heatsink temperature has exceeded 185 °F (85 °C)
and the solar and load is disconnected. The controller will
automatically reconnect when the heatsink cools to 176 °F
(80 °C).
Load Overcurrent
If the load current exceeds the maximum load current rat-
ing, the controller will disconnect the load.
The controller will attempt to reconnect the load two (2)
times approximately 10 seconds apart. If the overcurrent
condition remains after the first two (2) attempts, the fault
must be cleared by removing and reapplying power.
This error can also indicate a reverse polarity on the bat-
tery. Check wiring.
