The ControlBox 300 offers a wide range of open-loop and	tinuously approaching the setpoint
closed-loop control functions, e.g.:
– Specification of a fixed active power for all individual	The SINVERT PVS ControlBox 300 offers the following
SINVERT PVS inverters in the PV plant, e.g. setpoint	connection options:
value = 2 MW (active power fixed value)	– SIMATIC components with digital inputs
– Specification of a fixed reactive power for all individual	– SENTRON PAC3200 Power Monitoring Device for
SINVERT PVS inverters in the PV plant, e.g.	measuring actual values at the grid feed-in point
setpoint value = 100 kvar inductive (reactive power	– 4 x RJ45 ports
fixed value)	– 2 x fiber-optic ports, for cable lengths up to 5 km
– Specification of a fixed power factor cos ϕ for all
individual SINVERT PVS inverters in the PV plant, e.g.
setpoint value = -0.95
– Regulation of the active power for the individual
SINVERT PVS inverters in the PV plant as a function of
the active power actually measured at the grid infeed
