PV/Genset

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.

What does the system do in self-consumption applications?

In self-consumption setups, the ECpv controller ensures that solar production never exceeds the local load, preventing power from being fed back into the public grid. This works for both simple rooftop installations and advanced sites such as factories or campuses with multiple PV feed-in points. If control over PV production is lost, the ECpv can automatically trip a relay to fully disconnect the PV plant until control is restored.

How much fuel can I save?

Fuel savings depend on load profiles, generator setup, and PV system size. The ECpv prioritizes solar energy and can theoretically achieve PV penetration of up to 70% of the load, limited by minimum genset load. Due to solar availability and nighttime consumption, average diesel fuel savings are typically around 20%. We recommend careful system design and realistic calculations, or working with professional consultants.
