Second-generation controller for decentralized energy systems

Flexible control of PV, grid export, self-consumption, and gensets

Overview

ECpv2

Description

The ECpv2 is the second-generation ENcombi plug-and-play controller for decentralized PV plants, with or without gensets. Building on the proven ECpv platform, ECpv2 adds a wide range of new features designed to give you even more flexibility, performance, and control.

The controller connects seamlessly to inverters, controllers, and power meters via RS-485 or TCP/IP, giving you full control of grid export and self-consumption. It supports curtailment during negative energy prices and enables safe and efficient genset operation in hybrid plants, helping to significantly reduce fuel consumption. ECpv2 also supports load power meters as well as analogue sensors for weather data and fuel measurements.

Using the ECpanel, you get a true plug-and-play HMI operator panel without any need for application programming. Configuration, commissioning, and monitoring are easily handled through ECweb, which guides you step by step and provides comprehensive monitoring tools and detailed reports—accessible from both PC and mobile devices.

With the integrated EClogic feature, you can create custom control logics using a simple yet powerful programming tool. For advanced monitoring, the ECcloud remote monitoring system allows live and historical data visualization and analysis of your PV and PV-Genset plants.

The ECpv2 hardware is a high-quality, fast, and extremely compact unit, making it easy to install in almost any electrical cabinet. This makes it especially well suited for brownfield projects and retrofit installations.

Depending on the selected variant, ECpv2 supports: Up to 32 solar inverters Up to 16 PV feeders Up to 16 mains connections Up to 16 gensets in all PV/Genset variants

Product FAQ

ECpv2

ECpv2 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 with the license file downloaded from ECcloud at encombi.online.

Can I control more than 32 inverters, or mix inverter brands?

Yes, by stacking controllers. One ECpv2 controls up to 32 inverters of the same make.

For more, or for a mix of makes, each inverter cluster gets its own ECpv2, and a master ECpv2 sees each cluster as one large SunSpec inverter. A master handles up to 32 clusters, and masters can be stacked again. Gensets can be stacked the same way.

Does a PC or panel need to stay connected?

No. ECweb is only needed for commissioning; control of the PV, gensets and grid runs without it.

What happens to my settings when I update the software?

An update resets all settings and energy counters to their defaults.

Back up the settings and counters first (on the controller, a USB stick or the ENcombi cloud) and load them back afterwards. Updates are done with a USB stick or by swapping the SD card.

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.

Through EClogic, an RRCR signal can also pass power references from a superior control system.
