The easy way to save fuel in any size of PV/Genset plant


If you need to control, protect and monitor your PV/genset plant - the ECpv S, M or L is for you.

To control in PV/genset plants in need of a safe hybrid operations, the ENcombi ECpv hybrid controller features a communication line directly interfacing to the solar inverters. With this - the ECpv dynamically controls the power output of all solar inverters in the system in a linear and precise double decimal resolution.

The ECpv is applied in applications that requires:

  • Fuel saving in off grid PV/genset applications
  • Fuel saving in on grid PV/genset applications when backup gensets are running.
  • Power exported towards the grid is needed to be controller or not

Reading the power produced from the solar inverters is done via a communication line to a power meter or the solar inverters own measurements. The gensets should feature either an ECpv compatible genset controller or a power meter. The power flow in and out from the public utility is also measured via a power meter if desired / power export control is a requirement.

In off grid applications, the ECpv can enable a spinning reserve in combination with a wide range of synchronizing genset controllers.

The ECpv supports breaker feedback from digital inputs as well as relay outputs. This could e.g. be applied in a Zero Export application or in case of a severe reverse power is being fed to the gensets. This will trip the solar breaker should there be power exported / reverse power fed to the gensets and inverters are not responding.

Finally the ECpv Modbus Slave port can also be used for external master control if you want to pair it with a PLC or SCADA system.

A single line example can be found here for an ECpv application:


All setup and onsite monitoring are done using our easy to use ECweb software.

The site data is freely accessible to read out via Modbus from your ECpv. The ECpv Modbus data will always be uniform for every site, no matter which brand and model of solar inverter and power meters you are using in the application.

When the ECpv is connected to the internet, it can produce consumption and production reports with values in terms of kilowatts, penetration, fuel saving, PV curtailments and performance ratio - but also report on financial performances.

In addition to live monitoring via ECweb and sharing live data via Modbus. The ECpv also logs plant data on SD card or USB - enabling a lifetime of logging directly in the unit, which you can utilize for your own analysis. Moreover, all data the ECpv reads - it can export to our ECcloud, FTP or MySQL databases, you can read much more about data acquisition and monitoring on our monitoring page.



ECpv S, M and L covers any size of solar plant and can easily interface to any genset controller, power meter and solar inverter. Check out the full list of supported models on the ECpv product page
