5.0 TROUBLESHOOTING

AVERTISSEMENT: Risque de

décharge électrique.

Un moyen de déconnexion de tous les poteaux

d’alimentation doit être fourni. Ceux-ci se déconnecte

doit être intégrée dans le câblage xe. Ouvrir que toutes

les source d’énergie se déconnecte avant de retirer le

couvercle de la contrôleur, ou accès au câblage.

5.1 Error Indications

NOTE: If an optional Morningstar Remote Meter is

attached to the SunSaver MPPT , use the self-diagnostic

feature to determine the cause of the error indication.

Refer to the Remote Meter Operator’s Manual for more information.

Status LED Error Indications

• Solar High Voltage Disconnect Flashing red

• RTS Shorted Flashing red

• RTS Disconnected Flashing red

• Damaged local temp. sensor Solid red

• Damaged heatsink temp. sensor Solid red

• Damaged input MOSFETs Solid red

• Firmware Error Solid red

1. Heartbeat indication flickers the Status LED off briefly every 5 seconds

Battery Status LED Error Indications

• Load High Voltage Disconnect R-G sequencing

• High Temperature Disconnect R-Y sequencing

• Remote Temp. Sensor Error Y/R - G/Y sequencing

• External Wiring Error G/R-Y sequencing

• Load Overcurrent Y/R-G sequencing

• Load Short Circuit G/R-Y sequencing

• Custom Programming Fault R-Y-G sequencing

• Self-test Error R-Y-G sequencing

5.2 Common Problems

Problem: No LED indications

Solution: With a multi-meter, check the voltage at the

battery terminals on the SS-MPPT. Battery voltage must be

at least 7V to power the SS-MPPT.

Problem: The SS-MPPT is not charging the battery.

Solution: If the Status LED is solid or ashing red, see

Section 5.1 - Error Indications. If the Status LED is off,

measure the voltage across the Solar input terminals of

the SS-MPPT. Input voltage must be greater than battery

voltage. Check fuses and solar wiring connections. Check

solar array for shading.
