I am having a problem with 2x Growatt SPF 5000 TLM inverters shutting down when Lithium batteries are full.
When in full sun the three 200a batteries will charge to capacity in 2 hours .
I need to limit the solar input by switching off the 28 x 400 watt panels , 2x strings of 14, or both inverters shut down and no power to the house .
I have tried many different settings and talked to Rosen Solar who supplied everything as a complete kit ,
but just cant get the inverters to stay on when batteries are charged .
I have tried a factory reset , adjusted settings in many ways but whatever is done the shutdowns continue .
During high summer 2 x A/C units ran 12 hours a day so this draw balanced the demand and no shut downs .
Now there is lower demand the batteries reach full very quickly , it seems weird that the inverters cant monitor the batteries and stop the charge coming in when full ?
surely this is a main function of inverters ?
Has anyone else suffered this issue ?
