Hi,

I just want to know if the following is normal or not.

When my battery get to 15% it disconnects. (no problem with that)
Then as the sun comes up and the solar panels start charging the batteries, it will switch on the appliances and disconnects immediately again, as if there is not enough power, it keeps doing that a lot.

Is there a setting to stop this connect/disconnect till there is enough power and only then allow power to the appliances. (for now I disconnect the main on the circuit breaker till it is on 16 or 17% SOC), but what if I am not at home.

Thanks

Adjust your setting 11 to say 22%. When you do find it disconnecting if you have grid charge it up to about 25%. It might be set not to use grid. If this problem happens every night use your timer to go to grid at a certain time. 

The switch off in the morning is because PV is still weak and then the battery is discharged again. Keep your load low in the morning until the battery is charged enough. 

More information like size of PV and number and size of battery will also help to give more help. 

Just my input to try and help.

Thanks for the reply, I do not have grid 100% off grid.

Most days we make it through just when we have two days bad weather we might not make it to the morning.
