We offer a cloud-based real-time Analytical Monitoring of PV installations - from small rooftop systems to large ground-based PV power plants and floating PV systems in the multi-MW range. SERIS has developed a highly reliable and scalable monitoring platform to accommodate multiple deployments in different regions across the world. We have successfully deployed over 100 systems to-date and our monitoring capabilities are operational in Singapore, Australia, Cambodia, China, Germany, India, Indonesia, Malaysia, Philippines and Vietnam.
Analytical monitoring consists of a detailed measurement of critical system parameters and their analysis through mathematical modelling and scientific-technical evaluation. The monitoring system provides instant output verification, failure detection and alarm triggers. The features of the system, which can be customised to individual requirements, include:
- 1-second temporal resolution for various DC and AC parameters of a PV system, plus meteorological parameters such as irradiances measured with different devices and inclinations, temperatures (module, ambient), relative humidity and wind speed/direction
- Central Data Management – A cloud-based Web portal for customers to access the acquired real-time and historical data from PV systems
- Tailoring of alarms according to the customer’s needs (e.g. upon inverter trips, grid outages, system underperformance, etc), including SMS service
- High-quality visualisation of measured data online or on screens for various target groups: operations managers, engineers, general public (e.g. through displays in corporate entrance areas)
- Automated daily download and data back-up routines through a secure virtual private network over 4G connection.
- Highest data security through VPN connections over 4G network
- Submission of live power and irradiance data compliant with requirements from power system operators (PSO), e.g. Singapore’s Energy Market Authority (EMA)
- ± 150 ms time synchronisation with cloud-based time servers
Upon a system failure, SERIS engineers receive a warning (e.g. via SMS), thus enabling a fast reinstatement of the PV system’s operation.
