I want to change my grid connection from 150A 3 phase to 80A 3 phase to save costs. The problem is I need to provision for load spikes that exceed the 80A supply and I do not have control over the loads (Commercial tenants). I am planning to add 3 x 15Kw Quatro inverters to the supply, but I want to know if there is a way to allow and control feedback from the battery bank / charge controllers to negate / mitigate load spikes when the loads reaches 70A or higher on a phase or more. So if a phase needs 100A, I want to supply 30A from the inverter / battery bank instead of causing the grid to trip.
Can this be done in ESS, MQQT or Modbus if I add a 3 phase CT meter to monitor the loads? How would one program this and what equipment is needed?
