Parameters

Name	Description	Value	Level
ski	Subject Key Identifier (SKI) SKI of the FNN control box (shown in its web interface)		optional
ip	IP address Example: 192.0.2.2		optional
productionnominalmax [W]	Installed generator power (Wp) Rated generator/module power (Wp) of the installation.		optional
consumptionnominalmax [W]	Max. consumption power (grid connection) Contractual maximum power of the grid connection point reported to the control box. This is the connection capacity agreed with the grid operator, NOT the minimum consumption power (Pmin) of the control box. Default 24.15 kVA (3x35A).		advanced
failsafeconsumptionpower [W]	Failsafe consumption limit (Pmin, LPC) Failsafe minimum consumption power (Pmin) for controllable loads applied when the heartbeat from the control box is lost; it is overwritten by the control box once it transmits its own failsafe values. (Default 4.2 kW)		advanced
failsafeproductionpower [W]	Failsafe production limit (LPP) Remaining maximum feed-in power applied when the heartbeat from the control box is lost. Initial value; it is overwritten by the control box once it transmits its own failsafe values.		advanced
failsafeduration	Failsafe minimum duration Minimum time the failsafe limit stays active once entered. Initial value (default 2h); the control box overwrites it once it transmits its own value.		advanced
