First-generation plug-and-play controller for decentralized PV plants

Legacy model – see ECpv2 for new installations

Overview

ECpv

Description

Introducing the first-generation ENcombi Plug-and-Play controller, designed for decentralized PV plants, with or without gensets. While we continue to support and provide bug fixes for ECpv units, we recommend using the new ECpv2 for future installations. The ECpv2 offers additional features at the same price while maintaining the same user-friendly experience as the ECpv.

Easily connect to inverters, controllers, and power meters via RS-485 or TCP/IP for comprehensive management of grid export and self-consumption. The ENcombi controller also enables safe genset operation, helping you save fuel in hybrid plants.

(see ECpv2 for new designs)

Variants ECpv Logger: Logs data from utility, gensets and PV inverters.

ECpv Solar: Only PV control. Inverter power unlimited

ECpv S: PV/Genset. Inverter power up to 100KW

ECpv M: PV/Genset. Inverter power up to 500KW

ECpv L: PV/Genset. Inverter power unlimited

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 ECpv 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 32 solar inverters, 16 PV feeders and 16 mains connections in all variants and up to 16 gensets in all PV/Genset variants

Product FAQ

ECpv

ECpv questions

What does ECpv2 have that ECpv doesn't?

ECpv2 was built on ECpv version 1.86.0 and added analogue IO modules and analogue sensors, fuel level and fuel pressure sensors with a fuel level alarm, and load meters that can also be used for control.

It also added control of multiple inverter clusters via Huawei SmartLogger, Sungrow COM100E or SMA inverter managers.

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 my ECpv to another variant?

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 with the license file downloaded from ECcloud.

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

Yes, by stacking multiple ECpv units. Stacking is supported on the Solar, S, M and L variants, not on Logger.

What happens to my settings when I update the software?

An update resets all settings and energy counters. Back them up first (on the controller, a USB stick or the ENcombi cloud) and load them back afterwards.

Updating via USB stick is supported from ECpv version 1.56.0 onwards.

What does it log, and where?

A lifetime event log, summary logs and production time-series logs, stored on USB or the SD card.

Alarms are sent by email, and logs can be sent by email or FTP.

Can a SCADA or PLC system control it?

Yes. It works as a Modbus TCP server, and as a Modbus RTU slave on an RS485 port not used for inverters, meters, gensets or sensors.
