Solution Overview
EMS SOLUTION
Customer Pain Points
PV output fluctuates
Weather and irradiance changes cause PV power to vary frequently, and storage dispatch must be reviewed against PV-side behavior.
Generation and load do not always match
Daytime PV output may not align with site load, making surplus management and storage absorption important.
Anti-backflow is multi-variable
Grid-point power, load power, and storage power need to be monitored together.
PV and storage data are split
Inverters, BMS, PCS, and meters often sit in different systems.
Revenue and energy accounting is unclear
Generation, consumption, charge/discharge energy, and surplus power need one accounting view.
Exceptions need cross-device context
PV curtailment, storage not charging, or reverse power needs a cross-device trace.
EMS SOLUTION
Solution Description
PV-storage EMS starts from PV-side data. It connects inverters, combiners, weather sensors, storage PCS, BMS, grid meters, anti-backflow meters, and load meters to show generation, consumption, charging, and discharging in one energy flow.
Storage dispatch is reviewed together with PV output, site load, and grid-point power, so a PV-storage site is not operated like a generic storage plant.
The platform records generation, consumption, charge/discharge energy, self-consumption, and surplus power conditions for PV consumption review and anti-backflow strategy tuning.
