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 Current Compensation

12 Volt –15 mV per amp of load

24 Volt –30 mV per amp of load

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.
