Victron Comms with a Fronius Tauro?

Can Victron communicate and control with the Fronius Tauro as it can with Primos, Symos and Ecos?

The official statement from Fronius is that the Tauro is not approved in combination with Victron.

That’s mainly due to two reasons.

1. Flicker

2. Unable to test it thoroughly


Basically, the Tauro works with the Victron System as any Fronius inverter does.

But for now there has only been limited controlled testing possible. Some of these tests showed some flickering around the Victron zero-power point (PV equals load)

Until the software for bringing the flicker down to normal levels is available, we decided to officially not approve it.


As said, it works, but there are issues, so the risk of using the Tauro in combination with Victron is on the customers side.

As a further anecdote, there are large systems operating in the field without reporting issues as well.

Hey Guy, could you elaborate on what the implications of flickering around zero-power point would be?


Could you perhaps also elaborate on whether the Tauro supports frequency-controlled power reduction so you could hook up a battery to the system?

Hi is there some progress? We would like to use this combination at the instalation where we want to use 12x quattro 15kVA, 22x MPPT RS450/200 + 4x Fronius Tauro. So it´s could be useful to know if is it possible. Thanks. Tomas

Hi,

I have installed 6xQuattro15 and 2xTauro 50 and it is working perfectly.

1. flickering only occurs if more strings are added to the Tauro while it's inverting.

- solution to eliminate flickering, ensure all PV string are connected to the Tauro prior to AC connection. I had the flickering problem, did this and it was solved.

2. It responds to frequency shift and the setting is available.

Hi.

Will the energy ESS reverse feed limitation work when the Fronius Tauro is connected at the AC input?

Will I also need an energy meter at the power input?
