The amount of time between a green SOC indication and
load disconnect will depend on many factors including:
• rate of discharge (amount of load draw)
• 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 MPPT load outputs together in
parallel to power DC loads with a current draw greater than
25 or 30A, depending on the ProStar MPPT model in use.
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.

KEY:
G = green
G - Y - R = flashing sequencially
Y = yellow
G / Y = flashing together
R = red
G / Y - R = G and Y flashing together,
alternating with R flash

4.4.2 Status LED
The Status LED indicates charging status and any exist-
ing 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 lists
the Status LED indications.
