PPC
One Controller for Grid-Compliant Plant Output.
The Intellisolar Power Plant Controller (PPC) sits between the grid operator and your inverters, measuring at the Point of Interconnection (POI) and coordinating every inverter so the whole plant behaves as a single, grid-code-compliant generator.

Plant-Level Closed-Loop Control.
The PPC closes the loop between grid operator commands, POI measurements and inverter setpoints, so the plant follows dispatch and grid-code requirements automatically.
SLDC / GRID OPERATOR
Active power limits, power factor and reactive power setpoints arrive from the grid operator over SCADA.
POWER PLANT CONTROLLER
Compares POI measurements with the targets and calculates the setpoint for every inverter.
INVERTER FLEET
All online inverters follow their share of the plant setpoint, so the plant responds as one unit.
POINT OF INTERCONNECTION
POI meters feed active power, reactive power, voltage and frequency back to the controller.
SLDC / GRID OPERATOR
COMMAND RECEIVEDActive power limits, power factor and reactive power setpoints arrive from the grid operator over SCADA.

Active Power Control
CURTAILMENT & RAMP-RATE LIMITING
Limit plant output to the commanded setpoint and control how fast it changes.
Plant Control & Grid Compliance, in One View.
Monitor POI active and reactive power, grid frequency, SLDC setpoints, controller modes and inverter dispatch in real time from one supervisory interface.
Grid Compliance Without Manual Intervention.
Keep your plant compliant with the grid code and the utility's dispatch instructions while getting the most from your generation.
FOLLOW GRID DISPATCH
Act on curtailment and setpoint commands automatically and confirm the plant has responded.
STAY WITHIN GRID CODE
Hold power factor, voltage support, ramp rates and frequency response within interconnection limits.
ONE PLANT, MANY INVERTERS
Coordinate multi-vendor inverters and storage so the plant responds as a single generator.
COMPLETE AUDIT TRAIL
Keep a timestamped record of every command and response for utilities, regulators and commissioning.
