Issue description:

Hi!

Maybe im just thinking this wrong but im not able to get house to use loads from battery, it´s always using grid, i forced it to take from battery by cutting the mains to the house and forcing offgrid mode that way, then the battery started to feed the house (1.9kWh in picture) otherwise never. Peakshaving aint seeming to work and night time (after 19:00 until 07:00 in morning) i would like it to use battery instead but no luck.

Maybe im ust thinking wrong or missing something in the setup?

I use without battery life, but you need to look at the settings in your ess control especially the max soc and your grid set point
