Overview

ECpvX

Description

ECpvX is the ENcombi plug and play controller for microgrids and BESS control. Pick any interface protocol from our list and connect - it is that easy!

ECpvX works as grid interface for frequency and arbitrage interface and offers grid energy pricing for 30 energy markets in Europe.

Connect with solar inverters, BESS systems, genset controllers and power meters via RS-485 or TCP/IP and the ECpvX will be able to balance your power sources.

Using the ECpanel, you have a plug and play HMI operator panel without doing any application programming.

Setup and monitoring is easily done via the ECweb, describing every step of the setup and providing you with a wide range of monitoring and reports - run it on your PC or on mobile devices. With the new EClogic feature, you can program custom logics - a simple and powerful tool.

Use the ECcloud remote monitoring system web app for live and historical data visualization and analysis or your PV and PV-Genset plants. You can get to try it out for a full 90 days free of charge when purchasing any ECpvX variant.

The hardware is a high quality, fast and extremely compact unit allowing you to fit it into almost any electrical cabinet at your site when doing brownfield projects.

As standard, the unit covers up to 16 PV feeders, 1 Energy Storage System and 16 main connections in all variants and up to 16 gensets in all variants. Unused metering points can be utilized for load measurement via power meters.

Product FAQ

ECpvX

ECpvX questions

What are the hardware specs?

A DIN rail unit of 107 × 22.5 × 119 mm (H × W × D), weighing about 200 g.

It runs on 24 VDC ±15% (250 mA max) and operates from −20 °C to +70 °C. It has 1 × Ethernet and 2 × isolated RS485 ports, and an 8 GB industrial-grade SD card is included.

Can I upgrade to another variant later?

Yes. All five variants run on the same hardware.

After buying a license or extra, you activate it in ECweb, either online or from a USB stick.

Can the battery keep the site running if the grid fails?

Yes, with grid backup enabled the battery continues operating without the grid.

You can also keep a reserve: below a set state of charge the battery stops discharging, and it resumes once it is back above a second threshold. The same backup settings exist for operation alongside gensets.

When several systems ask for battery power, which one wins?

There is a fixed priority, from lowest to highest: normal control, ECopti, the charge/discharge scheduler, ECapi, Modbus, ECgrid, P(f) grid support (LFSM), RRCR and IEC104 commands from the grid operator, and an ECpvX master.

Whatever is in control, the state-of-charge window and transformer protection always limit the power.

Can a grid operator or SCADA system send commands?

Yes. Grid operators can limit the whole plant, PV and battery combined, via RRCR or via IEC104 through an external converter.

A SCADA or PLC can send power demands as a Modbus TCP client or a Modbus RTU master on a free COM port, and ECapi accepts them over REST.

Can I schedule when the battery charges and discharges?

Yes. ECpvX has an hour-by-hour charge/discharge scheduler.

Can I go beyond 32 inverters, or mix inverter brands?

Yes, by stacking. Each cluster of up to 32 inverters of the same make gets its own ECpvX, and a master ECpvX controls them all. Gensets can be stacked the same way.

For many batteries, ECpvX Cluster pools a group of ECpvX controllers under one master.
