Choosing the right products

Which controller fits my site?

ECpv2 is for PV plants with or without gensets: it controls grid export and self-consumption, and saves fuel in hybrid plants.

ECpvX is for microgrids and BESS, balancing solar, batteries, gensets and power meters. ECpvH is for PV and PV-hybrid plants with on-grid hybrid inverters.

ECpv, the first generation, is still supported with bug fixes, but we recommend ECpv2 for new sites: more features at the same price.

What do Logger, Solar, S, M and L mean?

Logger only logs data from the utility, gensets and PV inverters. Solar controls PV only, with unlimited inverter power; on ECpvX, Solar controls both solar and BESS.

S, M and L are the PV/genset variants, for inverter power up to 100 kW, up to 500 kW or unlimited. On ECpvX they are microgrid variants for up to 100 kW, 500 kW or unlimited BESS and PV.

ECpvX Cluster controls up to 32 BESS.

How much can one controller handle?

ECpv2 handles up to 32 solar inverters, 16 PV feeders and 16 mains connections, plus up to 16 gensets in the PV/genset variants.

ECpvX covers 16 PV feeders, 1 energy storage system, 16 mains connections and up to 16 gensets. ECpvH covers 16 on-grid hybrid inverters, 16 PV feeders, 16 mains connections and up to 16 gensets.

Unused metering points can be used to measure load with a power meter.

Will it work with the equipment I already have?

The controllers connect to inverters, genset controllers, power meters and sensors over RS-485 or TCP/IP. Each product page lists the supported brands and models.

The hardware is compact enough for almost any electrical cabinet, which makes it well suited for retrofits.

If a site has both on-grid and hybrid inverters, possibly from different brands, ECpvH and ECpvX can be used together.

I don't have a cabinet. What are my options?

ECcube is a pre-wired, pre-assembled switchboard: connect the power and communication cables through the bottom plate and it is ready.

It comes as ECcube2 Logger or Solar and ECcubeX Logger or Solar, with the RUT241 as its standard modem.

What do the add-ons do?

ECsync gives a BESS seamless switching between on-grid and off-grid when the BESS cannot do that itself. It needs an ECpvX or ECcubeX.

ECgrid lets an ECpvX deliver frequency ancillary services, working with any third-party aggregator. ECev limits EV charger power to what the site has available.

ECopti runs on ECpvX and uses machine-learning forecasts of PV production and load to optimise self-consumption and arbitrage.
