Basic understanding of a PCS Inverters

Today’s session dives deeper into the fundamentals of Sunsynk’s C&I Power Hub and the role of the PCS (Power Control System). We explore the difference between on-grid vs off-grid systems, why on-grid is more cost-effective, and how it’s ideal for energy storage, grid balancing, load shaving, and buy-low/sell-high strategies. The video explains how a PCS works as a bidirectional inverter – charging and discharging batteries – but without the extra components of a hybrid system (no MPPTs, ATS or full transfer switch). We also break down star vs delta configurations, how voltages are calculated, and why PCS units are mostly three-phase. There’s an in-depth look at transformer use, their benefits (galvanic isolation, safety in certain jurisdictions like Hong Kong), and their drawbacks (losses, inefficiency at low loads, harmonics, and power factor issues). Finally, we highlight why a PCS is only one part of the full system – it needs the EMS and HMI to function properly – and set the stage for the next video, where we’ll cover the STS (Seamless Transfer Switch). This video provides the technical grounding to understand how PCS fits into a modern power hub and why choosing the right configuration matters for efficiency, compliance, and cost. #Sunsynk #PowerHub #PCS #EnergyStorage #HybridInverter #CNI #CleanEnergy #SolarEnergy #BatteryStorage #GridBalancing #LoadShaving #Renewables #StarDelta #EnergyManagement #GreenTech #SmartPower #Transformer #Efficiency #OnGrid #OffGrid #EnergySolutions
