What is your setting for cut out? This can happen if your setting is that high. 

Also, please advise if its only the screen that's switching off or everything including Output:

 

1. It could be that the cut off Voltage in set point 29 is too high/ Please ensure your battery is in constant communication with the battery through BMS.

2. It could be that you have set the inverter on Power save mode and if the loads go to below a 100W the inverter goes into Idle mode i=and switch off.

3. It could also n=be that the inverter was over-loaded at the time and by design, to protect itself it will switch off instead of blowing up a component to self distruct.

 

Please advise accordingly to proceed.

Hi SEGEN SOLAR and Scorp007

My cut off v is 44v as per Hubble settings .

The inverter switch of completely no power going out and battery was at 70% according to batt indicator and 50% shown on inverter and load on 2500w .

I'm installing a Hubble cloud link this week the i will have more info what i picked up the inverter don't show correct battery percentage as indicator on battery . we had power failure yesterday for 14hrs and bat went down to 25% on inverter but batt Led's show 50 (kodak OG7.2 with 2 x Hubble am2 5.5kw no BMS link between inverter and batt )

@Riaancam  is grid on or off at the time?

Also what is the discharge ampere rating of your batteries? I am trying to ascertain wether your 7.2kw machine  peak discharge demand can be met by the battery. 

EDIT : Ok I noted you mentioned machine was idle, no load power. Ignore my questions.

BritishRacingGreen we had a power failure of 14hrs and I don't have panels on yet waiting for stock so no incoming power .

The first trip was in online mode and second was batt mode both was max load of 2500w and max batt A of 29A and inverter switch of completely
