Load Control Information - Morningstar SunSaver MPPT Serie Manual De Instalación Y Operación

Load Control Information

The primary purpose of the load control function is to disconnect
system loads when the battery has discharged to a low state of charge
and reconnect system loads when the battery is sufficiently recharged.
CAUTION: Do not wire an AC inverter of any size to the
load terminals of the SunSaver MPPT.
Load Control Settings
Load control is fully automatic. Choose between two (2) factory Low
Voltage Disconnect (LVD) and Low Voltage Reconnect (LVR) settings by
adjusting switch #2.
Current Compensation
All LVD and LVR setpoints are current compensated.
System Voltage
12 Volt
24 Volt
General Load Control Notes
• A 15 V maximum regulation voltage limit (30 V @ 24 V nominal) exists
for all battery types.
• Do not wire multiple SunSaver MPPT load outputs together in parallel
to power DC loads with a current draw greater than 15A.
• Exercise caution when connecting loads with specific polarity to a live
load circuit.
Protections
Solar Overload
(No LED indication) The SunSaver MPPT will limit battery current to the
15 Amp maximum rating.
Load Overload
(Battery Status LEDs: R/Y-G sequencing) If the load current exceeds the
maximum load current rating, the SS-MPPT will disconnect the load.
The SS-MPPT will attempt to reconnect the load two (2) times. Each
attempt is approximately 10 seconds apart. If the overload remains after
two (2) attempts, the load will remain disconnected until power is
removed and reapplied.
Current Compensation
–15 mV per amp of load
