hi,
Here in Belgium we have some as capacity tariff.
It’s works little as follow, for example if you use max 1000watt over your line, you need to pay 50€ each year, if your max capacity reach 2000watt, you pay 100€, 3000watt 150€ etc…
So if you have and EV and you charge 11kw (11000watt), its 11x50 = 550€
tis charge is only use the grid, the energy price etc is seperate.
How i spending some hours already in node red, but i dont get it how i want it 
Can somebody help me out?
I have Multiplus II 5000va, and 2 batterypacks of 314ah.
I use Batterylife.
What i want is monsty for dark wintermonths.
You have a “active soc limit” on batterielife.
So in wintermonths that limit is high, around 80% so mostly battery is charging little but during day but few hours later is idle again on that active soc limit.
For me it’s fine like that, but i want 1 eception.
At everning when i cooking, it’s take like example 3000watt.
I want when the 3 phase measuring is bigger then 2500watt, that my gridpoint will set on 2500watt and that ESS will go on “optimieze without battery life” so i get the other 500watt from the battery to avoid getting peak over 3000watt on the grid.
After cooking, when my usage is stable again, i want to go back to “optimize with battery life” and gridpoint back to 0watt.
Can somebody help me out how to script it on node red?
