Battery cable sparks when connected
• Put the built-in battery breaker in the off position before connecting or disconnecting batteries.
Battery symbol on the home screen is red
• The battery is under-Voltage or over-Voltage
Battery symbol on the home screen is yellow
• The battery is low, or the charge/discharge current is close to the programmed limit (which is ok)
Grid symbol on the home screen is yellow
• Grid parameters are out of specified range or grid is down
System has restarted
• It happens if the system is overloaded, battery voltage is greater than 63V, or Software update
Batteries were connected backward
• The battery breaker will trip. It can cause damage!
Why is the LCD screen still on when the power button is off?
• If PV or Grid power, LCD stays on, but the inverter and loads are off.
The Batt % meter is not reaching 100%
• The system needs to go through a small discharge/charge cycle first to calibrate the battery
Generator setup is reading 0Hz
• Select "General Standard" instead of UL1741. Then widen the frequency range to 55Hz-65Hz.
Color Touchscreen is Frozen
• Press and hold the escape button [] for 7-10 seconds
Troubleshooting Phasing Issues
If the Sol-Ark screen shows the above error, there is a phasing issue with your wiring, and it may cause overload faults
(F18, F26, F34) even with the Load breaker off and WILL CAUSE DAMAGE if left unchecked.
Single Sol-Ark: To locate the improperly wired phases, measure L1 to L1 (Top Screws) between the Grid and Load
breaker; you should see 0V AC. Repeat for L2 to L2 between the Grid and Load breaker. Attempt to correct the wiring
until you are only reading 0V AC between L1 to L1 & L2 to L2.
Make sure to correct both the Grid and Load wiring; they both need to be correct.
If the error persists, you will need to check your AC wiring beyond the inverter and may also need to verify that the
phases are properly labeled coming from your meter.
