I have an inverter connected to the garage where i have 4 battery (2x12v-150a=24v+2x12v-150a =24v ) in parallel, i have the 3.2kwh 24v model. Al the cablage seem correct , battery charge from utility is 60A and cut off settings is 22v ... something strange i try the capacity of my battery pack (7200kwh 50% of use=3.6kwh) the load is 600wh....Theoretical 6h of usage in battery mode... But after 45min all go to shutdown... Is somehing wrong in my settings or i have to check my battery? (battery are new)
