Inside
the System

Use ECassessment to perform feasibility studies for adding PV to a site or as a digital twin to compare expected vs actual performance for sites registered in ECcloud. ECassessment can load data from ECcloud or from CSV uploads and provides consistent graphical reporting identical to ECcloud. It supports custom datasets, up to one year of analysis, and can estimate base irradiance and temperature when weather data is missing.

Looking for a user-friendly, multi-functional logger for your site? The ECpv2 Logger interfaces directly with inverters, power meters, genset controllers and weather sensors to provide uniform Modbus data and live monitoring via ECweb. It is commonly used to integrate with onsite SCADA, capture fuel and power consumption for analysis and sizing, and log plant data locally (SD/USB) or export to ECcloud, FTP or MySQL for reporting and long-term analysis. The unit also supports breaker feedback (digital inputs) and relay outputs for protection and control.

If you need precise control of power exported to the public utility, ECpv2 Solar provides a direct interface to solar inverters and power meters and dynamically controls aggregate inverter output with linear, double-decimal precision. Typical uses include enforcing zero-export limits, allowing partial export, or capping export at a fixed power level. Production is measured via power meters or inverter measurements and grid flow is monitored by a utility power meter.

ECpv2 Solar supports breaker feedback (digital inputs) and relay outputs so it can trip breakers or signal status in enforcement scenarios. It also supports RRCR interface via digital input for export limitation and exposes a Modbus Slave port for external master control (PLC/SCADA). Onsite setup and live monitoring are available through ECweb; data can be logged locally (SD/USB) and exported to ECcloud, FTP or MySQL for reporting and analysis.

If you need to control, protect and monitor your PV/genset plant the ECpv2 S, M and L provide a scalable hybrid controller. ECpv2 interfaces directly with solar inverters, power meters and genset controllers and dynamically controls inverter output with linear, double-decimal precision to enable safe hybrid operation and fuel savings. It is used for fuel saving in both off-grid and on-grid PV/genset applications and can manage export or prevent unwanted export when required. In off-grid scenarios ECpv2 can enable spinning reserve with compatible synchronizing genset controllers. The controller supports breaker feedback (digital inputs) and relay outputs for protection, and exposes a Modbus Slave port for external master control (PLC/SCADA). Site setup and live monitoring are provided via ECweb; data can be logged locally (SD/USB) or exported to ECcloud, FTP or MySQL for reporting and analysis.

When you need to control charging, discharging and overall operation of a BESS while parallel to the grid, the ECpvX is an excellent solution. It manages active/reactive power export and supports zero-export/self-consumption, scheduled or automatic arbitrage (including ENTSO‑E spot-price integration), and grid-support modes (P/f or U/q) with configurable deadbands. ECpvX works in DC-coupled, AC-coupled or mixed systems, prioritizes PV to meet load, manages SOC-based dispatch, and logs data locally (SD/USB) or exports to ECcloud, FTP or MySQL. Monitoring, setup and remote service access are available via ECweb and EClink.

ECpvX is a scalable, universal microgrid control platform designed for safe and flexible operation of microgrids. It interfaces directly with solar inverters, BESS (battery energy management systems), genset controllers and power meters to dynamically control inverter and battery output with linear, double-decimal precision. ECpvX supports genset-parallel, grid-parallel and fully off-grid (grid-forming BESS) configurations and can be expanded over time from PV/genset to include BESS systems.
