SunSaver MPPT Installation and Operation Manual
4.0 OPERATION
LVD Warning
As the battery discharges the Battery Status LEDs will
transition from green to yellow and then from yellow to
ashing red. The ashing 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 (amount of load draw)
• capacity of the battery
• health of the battery
• LVD setpoint
If the battery discharges to the LVD setpoint the load will
disconnect and a solid red Battery Status LED indication
will be displayed.
General Load Control Notes
• A 15 V maximum regulation voltage limit (30 V @ 24 V
nominal) exists for all battery types. This limit ensures
that the battery and load terminal voltages will never
exceed 15 V/30 V. This protects certain DC loads that
may be damaged by high input voltage.
• Do not wire multiple SunSaver MPPT load outputs
together in parallel to power DC loads with a current
draw greater than 15A. Equal current sharing cannot
be guaranteed and an over-load condition will likely
occur on one or more controllers.
• Exercise caution when connecting loads with specic
polarity to a live load circuit. A reverse polarity connec-
tion may damage the load. Always double check load
connections before applying power.
