Fronius& victron 3-phase or 3-phase (3x8000) victron

Hi, I`m about to build my own pv plant which will include diy 60kW battery.

I also have Fronius Gen24 plus 10kW inverter and BYD 22kW battery, these could be optional, depends…

My house has 3x35A grid connection.

So, my questions are:

  1. I saw that there is now the certificate (EN50549-1)for 3x8000w multiplus 2 . Should I go with these…or should I have fronius and 3-phase multiplus ac coupled? and why so(please explain)
  2. If I go with 3-phase multiplus 8000, would they limit my grid power? 3x8000W > 3x6400W?

Battery size is either rated as capacity in Ah or energy Wh/kWh, while W/kW would be power. Your batteries can store 60kWh or 22kWh.

The Victron inverters are primarely rated in VA/kVA which is apparent power. In an AC circuit its not necessarely the same as active power W/kW. The Multiplus 48/8000 is rated at 8kVA or 6.4kW at 25°C.

I dont quite understand the actual question in point 1, are you asking if you should replace the Fronius inverter with a DC-coupled Victron PV system?

For point 2, the internal transfer switch can handle up to 100A, so when mains is available then the main fuses at 35A would be the limiting factor
