Troubleshooting Guide
LCD is not powering on
•
Check all connections- at least one of the following power sources is required: PV/Grid/Battery
•
Try pressing the power button, touchscreen, or navigation buttons
Panels are connected, but DC Light is not on
•
PV voltage must be 150V-425V | It’s night
Panels are not producing
•
Check for proper wiring on all solar panel connections
•
Turn PV disconnect “ON”
•
Check that the PV input voltage is not greater than 425V
•
If the system says PV = 0V, check PV polarity
Panels are not producing much power
•
PV Wire Strip Length: 5/8”. Your batteries are charged; you can test Grid Sell to verify.
The system does not keep batteries charged
•
Check the charge setting in the Charge Menu
Auto Gen-Start not working
•
Check to make sure your generator is compatible with Auto Start
•
Make sure that the Auto Gen Start wire is adequately connected to the Sol-Ark L12K-Tr and the generator
Normal LED isn’t on
•
Sol-Ark L12K-Tr is in pass-through-only mode, only a Grid connection.
•
Sol-Ark L12K-Tr is not working correctly (Call us)
The alarm light is on
•
Check the system alarms menu to identify the alarm
Grid HM value is negative when it should be positive (only applies in limited home mode)
•
Limiter Sensors are backward, L1/L2 sensors are swapped, or incorrectly wired L1/L2 sensors. Try Auto Learn.
AC Overload Fault or Bus Unbalance Fault
•
Check Transfer Switch/Subpanel wiring
•
Check for large loads that consume more than the inverter rating (EX: AC units over 3 tons)
The system connects to grid and quickly disconnects
•
With a DMM, verify your Neutral wire connection (should be 0 Vac referenced to GND)
•
Check your Freq is set to 60Hz, and the L12K-Tr measures 120V on L1 / L2 vs. N.
•
If overloading: verify 120/240V grid input and load output wires are not swapped.
DC Overload Fault
•
Check PV voltage
•
Make sure you have not wired more than two (2) solar strings in parallel
System is beeping
•
Check the system alarms menu to see which alarm has been triggered. Most alarms will self-reset.
•
There is no battery connected. If not using a battery, select no battery and disable activate batt in Batt menu.
Turn off the center button, remove AC Grid and PV Power for the 30s (screen is dead), and then power up
to fully reset the system.
Battery cable sparks when connected
•
Put the built-in battery breaker in the off position before connecting or disconnecting batteries.
