If you have parallel systems and turn one system off, you with get this notification. Not a fault.
Current Leakage from inverter AC output to Ground, check Ground and neutral are connected at the main
panel
It can happen when not using batteries or if Grid Input settings are changed. This is a notification, NOT a
fault. If you switch from No Batt to Battery mode, Power the System down completely to restart.
It is usually caused by Loads too large for the inverter. If off-grid, the battery discharge amps are
programmed too low. Overloads can result in F15, F18, F20, or F26.
Ground fault. Check PV+ or PV- wiring (which must be ungrounded). Exposed PV conductors + rain can also
cause. Check that the neutral line and Ground are not double-bonded (common with portable generators).
Overloaded the Load Output: reduce loads. Wiring Short on the AC Side can also cause this error. Overloads
can result in F15, F18, F20, or F26.
It is typically caused by DC current from the battery that is too large (ex: 4 Ton AC Unit). Overloads can
result in F15, F18, F20, or F26.
Initiated Emergency Stop; see sensor pinout table.
PV Ground fault. Check PV+ or PV- wiring (which must be ungrounded or damage can occur). Typically
caused by pinched PV wire grounding the PV+ or PV-. Grounded PV wire can cause F20, F23, or F26.
An exposed PV conductor combined with moisture is faulting (can cause F16, F24, F26).
No battery connection to the Inverter and Activate Battery is enabled. Disable Activate Battery in settings
while no battery is connected.
Too much load on one leg (L1 or L2) Vs. the other leg or DC loads on the AC output when off-grid. Grounded
PV wire can cause F20, F23, or F26.
Usually, a communication error for parallel systems, check cables and MODBUS addresses

Soft Start of large motor failed
AC Overload or load shorted. Reduce heavy loads.
Grid connection lost
Software DC overcurrent
Hardware DC overcurrent
Batteries exceeded their current discharge limit
If one system faults in parallel, this normal fault will register on the other units as they disconnect from grid
Grid under voltage causes a disconnect. This will self-reset when grid stabilizes.
Cannot communicate with other parallel systems. Check Master = 1, Slaves are 2-9, ethernet cables are
connected.
Grid over Frequency (common in power outages) causes a disconnect. Will self-reset when grid stabilizes.
Grid under Frequency (common in power outages) causes a disconnect. Will self-reset when grid stabilizes.
PV may be higher than 500V. Battery voltage should not be above 59V or 63V (depending on the model).
Batteries are overly-discharged, or Lithium BMS has shut down. If battery settings are off, this can also
happen.
Sol-Ark is programmed to BMS Lithium Battery Mode but cannot communicate with a BMS
Generator Voltage or Frequency went outside the allowable range
The parallel Slave system turned off without turning off Master
It can be a lousy PV connector/connection. And sometimes a false alarm due to powerful lightning storms.
Check the built-in fans are running; ambient temp may be too high
