Power Export 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.

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.
