Hello,
I'm new to Victron, ESS and Node-Red, so sorry if I ask stupid questions.
For the next winter I'm looking for a way to limit my grid power to 2500W. When the load in my house is low, I like to charge my battery to a certain level. But the total power from the grid must stay under 2500W.
I'm building this up step by step. The first step is to control the grid power.
As you can see on the bottom right there is something wrong with my calculation. The maximum charge power is to high. The battery would charge at 2526W.
When removing the wire from above the calculation works but the result is negative. Now idea how to do this calculation right.
Any help for this first step in a bigger project would be welcome.
Thanks.
