What do you need for a complete configuration of the Enphase Energy Router? – 4Blue B.V.

For a complete installation of the Enphase Energy Router, there are two variants: the standard IQ Energy Router and the extended IQ Energy Router+. The difference? You will find out that and much more in this article.

What is the Enphase Energy Router?

The Enphase Energy Router is a smart switching component within the Enphase Energy Management system. It allows you to control external consumers, such as a heat pump and charging station, within the Enphase domain and that without monthly fees.

There are two variants:

IQ Energy Router: for connecting with non-Enphase EV chargers
IQ Energy Router+: for connecting both EV chargers and heat pumps via SG-ready contact

Overview of required components per variant

Variant	Application	Required additional components
IQ Energy Router	Control EV charger	- IQ Gateway (Metered)
IQ Energy Router+	Control EV charger and heat pump (SG-ready)	- IQ Gateway (Metered) - Enphase Energy Meter (included) - SG-ready relay (included)

Note: The IQ Gateway (Metered) with current transformers is always necessary to support the operation of the Energy Router.

When to choose which variant?

IQ Energy Router

Use this if you want to smartly control an external EV charger (so not an Enphase charging station), for example to store surplus solar energy.

Compatible EV chargers: See this list from Enphase
Installation diagram: View the wiring diagram (EV charger)

IQ Energy Router+

Use this if you also want to connect a heat pump with SG-ready contact to the system, alongside your EV charger.

Compatible heat pumps: See this compatibility list
- If the heat pump is not on this list but does have an SG-Ready contact, installation is still possible but Enphase has not yet created a manual for it.

Frequently asked question: Do I need a separate Energy Meter and relay?

With the IQ Energy Router+, the Energy Meter and the SG-ready relay are included in the delivery.
With the IQ Energy Router, these components are not included and also not necessary.

The IQ Gateway (Metered) with current transformers is essential in both cases because it enables real-time monitoring and energy management within the Enphase ecosystem.
