Inverter accessories

Inverter accessories: selection and advice

An inverter rarely works alone. Meters, communication modules and connection parts complete it into a working system.

Buy accessories that match the brand and series of your inverter, because many components are manufacturer-specific. The type designation of the device is the best search aid.

You will find energy meters, smart meters and monitoring modules from Hoymiles, SolarEdge, Sungrow, Anker, Huawei and Kostal, among others.

With accessories, the details decide: a meter must match the grid type, a communication module the device generation. Therefore note the type and year of manufacture of your inverter before you order, and give us this information if you are unsure whether a part is compatible.

With meters and smart meters, the measuring method also matters. Models with current transformers measure contactlessly, others directly; whether measurement is single-phase or three-phase must match your grid connection. The product pages give the details.

Frequently asked questions

What is an energy meter for?

It measures consumption and feed-in, for example for self-consumption control and display.

Can accessories be used across brands?

Usually not; pay attention to the compatibility information.

Can I retrofit accessories?

Yes, provided your device supports the extension.

  • Fronius Ohmpilot 9.0 - 3 - NeueEnergie24 Fronius Ohmpilot 9.0 - 3 - NeueEnergie24

    Fronius Fronius Ohmpilot 9.0-3

    Deliverable in 7–14 working days  Estimated delivery time

    Fronius Ohmpilot 9.0-3 The Fronius Ohmpilot is a load controller for using surplus solar energy for water heating. Thanks to its continuously adjustable output from 0 to 9 kW, surplus PV energy can be used highly efficiently to supply household consumers. The Ohmpilot is primarily used for the intelligent control of heating elements for water heating in boilers and buffer tanks, but it can also be used for infrared heaters or towel radiators. A single-family home with average water consumption can therefore cover most of its hot water demand with solar energy from April to October. The result is maximum self-sufficiency, lower energy purchases for the household and no need for the building's main hot water supply during the summer months.
