Logging

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.

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.
