Hello,
I would like to know if there is any possible way to speed up frequency regulation by modifying the settings of the PV inverter assistant.
The system is off grid and consists of
- BYD LVL premium 15.4
- Bluesolar MPPT 150/60
- Quattro 48/8000
- Solaredge SE6000H (maximum expected PV-contribution is << 4500W)
The P(f) ramp at the Solaredge side is defined from 50.2Hz to 51.7Hz and disconnect @ 52Hz.
The Victron PV-Inverter assistant is configured for the same band with disconnect @ 52.1Hz. With 6000W inverter and 6400W PV.
I observe that once 55.2V are reached BYD sets the charging parameter to zero. However charging continues as the frequency ramp only rises slowly and therefore the SE inverter does not reduce its output fast enough. For now I throw off (via AC-OUT 2) the SE inverter once the voltage gets higher 57V. By that time frequency has only risen to 50.4Hz. Can the ramp rise time be shortened? Am I too carefull with the 57V limit? (cell details show almost 3.8V for the highest cell). Thank you in advance for your help and input!!
