How it works

The inverter has a WIFI transmitter that wirelessly connects with your WIFI enabled home router in the same way your laptop, mobiles and printer probably does (user name and password).

You set up a free account via the inverter manufacturer's website and the data flows from the inverter through your router to the manufacturer website, where you can then log in from anywhere and see what's going on in real time or run historical reports.

Who's got solar WIFI that actually works well?

Fronius, Huawei, SolarEdge, Goodwe, Sungrow, ABB and finally now... SMA

What about SMA?

The new Sunny Boy (SB) 40 range from SMA includes both a WIFI and a wired solution.

The LCD screen on the inverter is gone though.

Both the wired and WIFI solution uses Web Connect

How much extra for WIFI?

Huawei, Goodwe, SMA, Fronius and Sungrow WIFI is currently included free

ABB PowerOne is about $300 extra per inverter
SolarEdge is $90

What about other brands that claim to have WIFI?

Reliable WIFI is difficult. Our experience with other brands, WIFI has not been good.

Using a smartphone or PC connected via WIFI you connect to the WIFI hotspot created by the inverter, enter your home network details and password so the inverter can transmit data through your router. You then create an account on the manufacturers website which includes the details of your inverter and then the inverter transmits the solar data every few minutes to the website which you can then view from a Smartphone app or PC.
