Hi there!
I have an off-grid solar installation and EV being charged with Wallbox Pulsar Plus.
Currently, I control the start/stop and charging current with Home Assistant automation (through the cloud), mainly based on the batteries (lead-acid) charging current and voltage.
Changing current during charging is quite fast, taking 2-3 seconds, but starting/stopping takes about 10-15 seconds (sometimes even more). BTW I charge my Hyundai Kona EV... I imagine the time of start/stop can depend on the EV (but not sure).
When I saw that Victron has an EVCS and that it can be controlled via Node-Red, I thought it may significantly improve the EV charging changes, which is especially important for me being off-grid and willing not to strain my batteries (sometimes I have minimal loads in the house and the EV gets 7,4kW, then suddenly there come the clouds and the PV production drops to ~1kW, and the EV charger drains 6-7kW from the batteries and they suffer 15+ sec, which I do not like).
So the question to experienced EVCS/Node-Red users: how fast does EVCS react to changes ordered by Node-Red logic?
