LVD Warning:
As the battery discharges the Battery Status LEDs will
transition from green to yellow and then from yellow
to flashing red. The flashing red indication is a warning
that a low voltage disconnect event will occur soon.
The amount of time between a green SOC
indication and load disconnect will depend on many
factors including:
• rate of discharge - based on amount of load
current
• capacity of the battery
• health of the battery
• LVD set-point
If the battery discharges to the LVD set-point the load
will disconnect and a solid red Battery Status LED
indication will be displayed.
General Load Control Notes:
Do not wire multiple ProStar load outputs together
in parallel to power DC loads with a current draw
greater than 15 or 30A, depending on the ProStar
model. Equal current sharing cannot be assured and
an over-load condition will likely occur on one or more
controllers.
Exercise caution when connecting loads with specific
polarity to a live load circuit. A reverse polarity
connection may damage the load. Always double
check load connections before applying power.
4.3 LED Indications
KEY:
G = green G - Y - R = flashing sequentially
Y = yellow G / Y = flashing together
R = red G / Y - R = G and Y flashing together,
alternating with R flash
4.3.1. Power-up
Normal power-up: Status LED flashes G, then SOC
LEDS flash G - Y - R, then SOC LEDs indicate battery
charge status with a single battery status LED.
Failed bootload: Status LED flashes G, then SOC
LEDS flash G - Y and stop on solid Y.
4.3.2 Status LED
The Status LED 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
Status LED will flash red whenever an error condition(s)
exists. Table 4.4 below, lists the Status LED indications.
