Integrations

The Navigator supports various inverters, batteries, EV chargers, heat pumps and energy meters. You can find an overview of all supported brands and models, with the available connection methods per model, under Integrations.

We are constantly working on adding supported devices. Is your brand or model not on the list yet? Let us know.

In the meantime, you can often still measure the consumption or generation of the device with CT clamps or an energy meter. A device without its own control input can be switched on and off with a contactor.

Each integration requires its own connection and setup, depending on the brand and model. Therefore, always follow the manual of the device under Integrations first. Then add the device in the local web app via the installation wizard or via the components.

With Modbus RTU, you connect the device with a cable to the RS-485 bus of the Navigator. With Modbus TCP, the Navigator communicates with the device via the local network. You can see which connections a device supports per model in the overview under Integrations.

The Navigator and the device must be on the same network (and the same VLAN). In addition, set a static IP address on the device, or reserve the IP address in the router (DHCP reservation). This way, the address does not change after a restart and the connection stays stable.

With some brands, such as Growatt, Huawei and SolarEdge, the battery communicates via the hybrid inverter. The Navigator then reads and controls the battery via the inverter. With other brands, such as Neovolt, SAJ and Sessy, you connect the battery directly. See Batteries for the connection method per model.

Do you see a different charge limit in the manufacturer's app than in the Navigator? Then there is usually nothing wrong. Every battery has a lower limit below which it does not discharge any further. The EMS uses the value that has been agreed with the manufacturer per brand and type. The app of the inverter or battery often only shows its own default setting. So you see two numbers, but they refer to the same protection of the battery.

This lower limit is called the minimum SOC (state of charge). It protects the lifespan of the battery and prevents the warranty from being voided. The name of the setting differs per brand, for example discharge limit, end-of-discharge SOC or reserve SOC.

With brands where the Navigator controls the battery via the inverter, such as Huawei, Growatt and SolarEdge, the manufacturer's app or portal shows the default setting of the inverter, for example 5%. The Currentt App and the Navigator show the lower limit that the EMS maintains, for example 15%. The latter value applies in practice. After a firmware update of the Navigator, this value may be tuned more precisely, so you may suddenly see a different number.

The minimum SOC is fixed and cannot be changed by you. Do not change the discharge limit in the manufacturer's app either: the EMS maintains its own lower limit anyway, and you risk voiding the warranty. In doubt whether the settings are correct? Then request support and include a screenshot of where you see the value.

An integration in beta is already supported but still in development. Does something not work as expected? Then request support.

No. With a cloud connection, all communication goes via the internet. Both the EV charger and the Navigator must therefore be online permanently. If the internet connection drops, the Navigator cannot read or control the EV charger.

The Navigator controls heat pumps via the SG-ready protocol, with two contactors. Check the specifications or installation manual beforehand to see whether the heat pump supports SG-ready. You can find an overview of brands with SG-ready heat pumps under Heat pumps.

If both SG-ready contacts open, for example due to a broken cable or a Navigator without power, the heat pump automatically switches back to Mode 2 (Normal). The heat pump then runs according to its own control, so the installation always remains functional.

Yes. You then measure the generation with an external energy meter (CT clamp or Modbus meter) on the cable group of the solar panels. This method works with all Enphase systems, regardless of the Envoy model.
