Solar Short Circuit
(Charging Status LED: OFF) Solar input power wires are short-circuited.
Charging automatically resumes when the short is cleared.
Load Short Circuit
(Battery Status LEDs: R/Y-G sequencing) Fully protected against load
wiring short-circuits. After two (2) automatic load reconnect attempts (10
seconds between each attempt), the fault must be cleared by removing
and reapplying power.
High Voltage Input
(Charging Status LED: R flashing) If the solar input open circuit voltage
(Voc) exceeds the 75 volt maximum rating the array will remain
disconnected until the Voc falls safely below the maximum rating.
Battery Reverse Polarity
(No LED indication, not powered) Fully protected against reverse
battery connection. No damage to the controller will result. Correct the
miswire to resume normal operation.
Damaged Local Temperature Sensor
(Charging Status LED: R on solid) The local ambient temperature sensor
is short-circuited or damaged. Charging stops to avoid over- or under-
charging. This is a critical error.
Damaged Internal Temperature Sensor
(Charging Status LED: R on solid) The internal heatsink temperature
sensor is damaged. This is a critical error.
High Temperature
(Battery Status LED: R-Y sequencing) The heatsink temperature has
exceeded safe limits and the load is disconnected. The load will
automatically reconnect when the heatsink cools to a safe temperature.
Remote Temperature Sensor (RTS)
(Battery Status LED: R/Y - G/Y sequencing) A bad RTS connection or
a severed RTS wire has disconnected the temperature sensor during
charging. Charging automatically resumes when the problem is fixed.
To resume operation without a RTS, disconnect all power to the
SunSaver MPPT and then reconnect.
High Voltage Transients
Solar, battery, and load power connections are protected against high
voltage transients. In lightning prone areas, additional external
suppression is recommended.
Programming Custom Setpoints
Custom charging and load setpoints can be programmed into SS-MPPT
non-volatile memory using a PC with Morningstar MSView software
