Hi there. We have installed an AC / DC coupled system with a Quatro 15, and we have used a fronius 8kw inverter for the AC coupled side of things. The customer has an induction hob that doesn't work whenever the frequency has been shifted to control the Fronius inverter. Do you have any recommendations on how we can get around this? Thank you.
Give this a looky...

With fully supported hardware, the Cerbo can throttle the Fronius as opposed to on/off with frequency shift.
Frequency shift is always used in off-grid.
A kitchen appliance which does not support a frequency shifting of 2-3Hz is trash. ;-)
Here everything if fine with my Multiplus-II 24/5000 and the Fronius Primo 8.2-1 (8,61kWp throttled to 4,4kW), 1 SmartSolar 150/70 (1,86kWp), 2 SmartSolar 250/100 (2,05kWp each) and 3 table top Induction cooker (2x 2kW and 1x 1,6kW).

I use the Aux relay on my MPII to switch my solar PV inverter to 10% in the event of grid failure by using the RRCR (Radio Ripple Control Receiver) connection on my PV inverter. Then the frequency shift function is then a back up as 10% output from my PV array is lower than my base load therefore in theory my PV inverter should never have to stop in a grid failure situation.
