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 500V
• 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 is 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 15K and the generator
Normal LED isn't on
• Sol-Ark 15K is in pass-through-only mode, only a Grid connection.
• Sol-Ark 15K 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 15K measures 120V on L1 / L2 vs. N.
• If overloading: verify 120/240V grid input and load output wires are not swapped.
• If 120/208V, the L1 and L2 are phase-specific. So, you may have to swap Grid L1 / L2 for 208V applications.
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.
