AD-PVO 6100 GT

The AD-PVO 6100 GT photovoltaic optimizer monitors the feed-in of any surplus PV energy at a building's main connection. If the feed-in power exceeds a limit value parameterized by the operator, up to three independent load relays can be activated. These three load relays can be individually parameterized and can therefore switch loads either in phases or in steps to the total power. These switching relays can now be used to control electrical loads (e.g. electric heating element in the domestic hot water tank of the heating system, air conditioning unit or heat pump). With the AD-PVO 6100 GT, the energy is converted on site and not fed back into the public low-voltage grid. The use of this device optimizes PV systems for self-consumption and reduces the load on the public low-voltage grid. The AD-PVO 6100 GT also has various interfaces (RS485, Ethernet, WLAN, USB) for parameterizing the device or reading out measured values. A log function can be implemented with a USB stick. The temperature input can be used, for example, to measure storage temperatures and implement switch-offs and switch-overs. The two digital inputs can be parameterized as blocking inputs, for example, to ensure correct function in connection with an electrical battery storage system. The analog standard signal output or the PWM output can be used, for example, for stepless control of heating elements or pumps. All relevant measured values can be read on the integrated LC display. The device can be parameterized via a WEB interface or via the Adamczewski parameterization software AD-Studio. It can be integrated into the local network via Ethernet cable or WLAN radio connection. It is recommended that the AD-PVO 6100 GT is installed directly behind the energy supplier's meter in the switch cabinet, because the measurement should take place as close as possible to the feed-in point. The device requires all three phase conductor voltages and the neutral conductor for the measurement. The AD-PVO 6100 GT measures the currents via three external split-core current transformers, which can be mounted directly on the 3 phases after the meter to save space (without disconnection). The photovoltaic optimizer gets its own supply voltage from the measuring voltage L3. This means that no separate supply voltage needs to be connected.
