Solar, wind, hydroelectric, energy storage, self-consumption: a single cloud-based dashboard for all your renewable energy installations, regardless of the manufacturer.
Monitor each string inverter (SolarEdge HD-Wave, Fronius Primo, SMA Sunny Boy), each central inverter (SMA SC series, Schneider Electric Conext CL, ABB PVS-175), and each solar tracker (NEXTracker NX Horizon, Array Technologies DuraTrack). Read SunSpec Modbus registers: DC output per string (DCA, DCV, DCW), total AC output, Performance Ratio, and MPPT drop-out alerts.
Preconfigured Modbus templates for SolarEdge, Fronius, SMA, Huawei FusionSolar, and industrial BESS batteries. Open protocols: SunSpec Modbus RTU/TCP, IEC 61850, DNP3, DLMS/COSEM.
SOC, bidirectional power, temperature, mode (charge/discharge/standby)
SOC%, SOH%, total voltage, bus current, module temperature, cycle counter
500 kbps CAN interface or RS-485 Modbus RTU, depending on the firmware. 17 standard variables
Access via local JSON API on port 4444. SOC, PV power, battery power, home energy consumption
Industrial BMS compliant with IEC 61850: Over 200 data objects, ENTSO-E grid-scale storage compliance
From real-time production dashboards to ENEDIS regulatory reporting—all the business functions of a renewable energy operator in a single SaaS platform.
View real-time production in kW by inverter, by string, and by site; cumulative daily/monthly/annual kWh; and the Performance Ratio (PR), calculated continuously by comparing it to the measured irradiance (W/m²), the normalized power curve, and production forecasts based on local weather. Data is refreshed every 5 seconds via WebSocket.
When the output of an inverter or string falls below the expected threshold (based on the irradiance measured by the pyranometer), Eziwan automatically triggers a “low output” alert that includes: current value, expected value, percentage difference, and the name of the faulty string (SolarEdge optimizer ID or SMA MPPT). SMS, email, and webhook notifications are sent within 5 minutes.
Automatically generate your daily, monthly, and annual reports in PDF or Excel format: gross production (kWh), normalized production (kWh/kWp), monthly performance ratio, availability rate, and detailed system losses. Automatically send these reports via email to your lenders, fund managers, and banking partners on the 1st of each month.
String-by-string comparison of DC currents (DCA SunSpec Model 160 registers) makes it possible to detect an MPPT dropout, a module failure, or a connection fault on a specific string of the inverter. For SolarEdge installations with optimizers, monitoring is performed at the individual panel level. Precise location on the wiring diagram is important.
The Performance Ratio (PR = Actual Production / Theoretical Production) is calculated continuously and on a periodic basis. Theoretical production is calculated based on measured irradiance (Kipp & Zonen CMP3 pyranometer) or satellite data (Solargis Pvspot), depending on the configuration. The availability rate tracks every minute of downtime per piece of equipment and generates a monthly contractual availability report.
Generators with a capacity greater than 250 kWp are required to report to ENEDIS (daily production readings, hourly load curves). Eziwan automatically generates the reporting files in S21 format and transmits them via the ENEDIS CONNECT API. For solar farms subject to the TURPE HTA, 10-minute load profiles can be exported in CDX/CSV format, which is compatible with the DSO’s billing tools.
ENEDIS/RTE decrees, orders, and requirements: The Eziwan platform is designed to meet all regulatory requirements for remote monitoring and reporting by renewable energy producers in France.
SolarEdge Monitoring, Fronius Solar.web, and SMA Sunny Portal are brand-specific portals. Eziwan is the only multi-brand, multi-technology solution with a French sovereign cloud.
