Pyro Shield

Faulty readings, Data Loss, Diverging behavior, Irradiance at Night, Stuck values.
These definitely represent common irradiance data problems 
that result to unreliable calculation of KPIs,
thus causing invalid performance analysis and misleading reporting.
Pyro Shield is an intelligent analytics tool for evaluation of solar plants pyranometers’ proper operation and measurement accuracy. The new analytic enables plant operators to identify communication issues, malfunctioning instruments, underperformance due to delayed maintenance or need for re-calibration.
Pyro Shield analyzes measurements by performing a set of checks for data availability, validity and consistency, as well as intra-plant pyranometers correlation. It classifies the pyranometer alarm states and periodically notifies the user on their health status through a scheduled report.
Pyro Shield comes to meet the increasing operator needs for solar plant data quality, accurate performance analysis and asset health evaluation, built on top of the standard integrated pyranometers monitoring offered by Inaccess.

Inaccess CMS: Next Generation Architecture


Inaccess releases its next generation real time architecture which provides for the collection, presentation and storage of raw data from the field deployed controllers directly to the cloud-based central management system. Thousands of raw samples can be transferred over MQTT every second offering an unparalleled insight in several fast varying parameters of the solar plant. 

The efficient use of the storage systems is achieved by individually configurable data retention per signal which can vary from a few minutes to several years meeting demanding requirements while optimizing the use of resources. 

With this new architecture Inaccess CMS is now offering the same data resolution with Inaccess local SCADA systems. At the same time, the scalable design of the database and the backend software guarantees the system capability of hosting thousands of MWs without sacrificing performance or data resolution.

Inaccess Z-PPC: Accurate control for Zero Export PV installations

An increasing number of commercial installations use PV generation to offset their energy usage, provide corporate environmental stewardship and save money. At the same time grid operators need to maintain a reliable, secure supply of electricity to existing customers.  Export power limitation schemes serve exactly these two needs, requiring a maximum power export from the installation to the grid. Inaccess Z-PPC satisfies Export Limitation requirements for the most rigorous grid, using the plant inverters and meters/relays, providing near real-time capabilities for plant active power control. 

Indicatively, Z-PPC has been successfully commissioned in the recently inaugurated IKEA store in Columbus Ohio, providing accurate zero export limitation, while maximizing energy usage compensation from the store’s 1.2MWp PV array.
