Monitoring and Big Data Analytics for improved production
Renovagy has long-since provided monitoring across PV installations, for rapid location and repair of faults. In Munich, affiliate Big Data for Business Solutions (BD4BS), will show the results of using Big Data and Machine Learning in processing monitoring data to improve predictive maintenance and pre-empt faults.
Renovagy’s string monitoring solution for measuring current is now installed across 9.5GW of installed PV capacity worldwide. The company reckons monitoring systems, typically representing 0.001% of CAPEX, can improve OPEX by 4-5% ($1m over the lifespan of a 100MW plant).
Grids and micro-grids
In response to new grid codes in Spain and elsewhere, Renovagy is now immersed in intelligent and micro-grids—essential to an energy transition combining generation, storage and hybrid systems, says CEO Miguel Ángel Ayuso.
Renovagy solutions cover online and self-supply systems and include control of grid frequency and PV storage, as well as controlling grid connection and disconnection.
Through its Power Plan Controller (PPC)—Renovagy already offers rapid response control on Mexico’s demanding grid. It is adaptable to all types of central invertors and invertor strings.
Renovagy provides turnkey solutions for residential and industrial PV, covering everything from designing systems to operations and including the license and even PPA processing. Systems can be stand-alone—a fast growing market—or grid connected, with or without storage.
Through affiliate Energytion, Renovagy also integrates electric vehicle charging, combining its own energy control systems with in-house storage and rapid charging solutions, as well as microgrids.
In Munich, Renovagy will show its latest solution for balancing vehicle recharging with multiple charger systems connected to a single meter.
Innovations include rapid and semi-rapid chargers. The latter is a slim-line 43 kW AC unit (wall mounted or on-stand), with integrated meter and line protection. It is scalable from domestic use to large-scale infrastructures with multiple chargers, with OCPP server control, user control and management system for multiplatform billing.
Renovagy claims its rapid-charger models are “the most efficient on the market”, with SiC and PCBA technologies. They are low maintenance, without air filters, yet equipped for latest generation high-voltage 500-1000V vehicles in DC. They are very small, flat wall-mounted units, ranging from 25-50 kW in DC and 22-43 kW in AC, capable of integrating self consumption storage. The 32” tactile screen facilitates interactivity in commercial car parks.
Energytion will show its LiFePO4, lithium batteries of 4.1 and 9 kWh, scalable both in series and parallel. It will also present details of a 5 MWh lithium battery storage plant to enter operations in the Canaries this summer. Costs of lithium batteries have fallen in four years. The company expects the trend to continue.
The company will also exhibit its energy management system (EMS), for residential and commercial use, based on advanced AI. It balances storage, electric vehicle recharging, self-consumption and generation and external power supply. It integrates weather predictions with power production and price predictions and is capable of smoothing power peaks and load modulations.
