Solar SCADA & PLC Control Systems
Plant-level visibility for inverter fleets, metering, weather inputs, switchgear and grid-facing control interfaces.
Solar PV SCADA
Controls that make renewable assets operable.
Solar SCADA should give operators a clean view of generation, equipment status and constraints across the site. SES builds the integration layer around OEM inverters and plant controllers so the site is easier to operate, troubleshoot and report on.
SES role
The control and visibility layer
SES does not manufacture batteries, inverters, turbines or OEM plant controllers. We integrate them into a clear SCADA and PLC control layer so operators can see what is happening, understand why, and act with confidence.
Engineering scope
What we design, integrate and support
Clear responsibilities, structured data and operator-ready controls across grid-facing renewable assets.
Inverter fleet visibility
Aggregate inverter status, output, limits, warnings and fault data into clear operator screens and performance trends.
Metering and grid context
Bring export/import metering, transformer data and grid-facing signals into one site-level operating view.
Balance-of-plant control
Use PLC logic where deterministic sequencing, permissives, switchgear status or auxiliary system control is required.
Integration layer
Built around the equipment you already have
OEM systems stay responsible for their specialist protection and asset functions. SES makes the site coherent at plant level.
Inverters
Status, power output, fault codes, modes and setpoint handover where supported by the OEM equipment.
Weather and metering
Irradiance, wind, temperature and revenue or check metering for operational context and reporting.
Plant controller
PPC communications, mode visibility, limits, setpoints and interlock-ready signals.
MV/LV systems
Switchgear, transformer condition, auxiliary services and alarm handover into the main SCADA layer.
Operator outcomes
Less noise. Faster diagnosis. Better control.
A renewable SCADA system should help the site team make decisions, not simply collect tags.
Better curtailment context
Operators can distinguish equipment issues from grid or plant-level constraints more quickly.
Cleaner alarm handling
Inverter and site alarms are rationalised so the highest-impact events stand out.
Practical performance insight
Trends and structured tags support maintenance planning, operational review and future analytics.
Architecture
Solar plant architecture
Select each layer to see where SCADA sits around solar generation, conversion, metering and grid interfaces.
SCADA interaction: Panels
SCADA role: trending of generation performance, array/combiner fault indicators (when provided), and energy/balance context for operators.
Solar arrays convert irradiance into DC generation. SCADA typically works at inverter/combiner level rather than monitoring individual strings.
Integration with existing control systems
Solar SCADA often needs to work alongside existing control systems, Balance of Plant PLCs and established SCADA platforms. SES can help map signals, define control boundaries and integrate plant data so new solar assets fit cleanly into the wider site architecture.
Control system modernisation and SCADA migration ->Next step
Discuss the control layer before the site is locked down.
Early input on SCADA, PLC interfaces, data models and alarm philosophy prevents avoidable commissioning delays and makes the finished system easier to operate.
