F20 with no battery installed

Hi guys


I installed an 8kw inverter this week. Batteries will be coming soon, but for now I'm running without a battery.


Every time there's a power spike I'm getting an F20 error and the inverter shuts down.


I've checked no battery is selected on my inverter. Any idea why am I getting these errors?



Thanks

Hi Darren

F20 Tz_Dc OverCurr_Fault, please could you ensure that the PV current does not exceed the inverters parameters every time there is a power spike. Also bear in mind that you are limited to the maximum current you have coming down from your panels, should you try to draw more than panels can supply it will go into overcurrent fault.
