AD-PVO 2000 GT

Description

The Photovoltaic-Optimizer AD-PVO 2000 monitors the supply of solar energy to the main connection of a building. If the supply output exceeds a limiting value set by the customer via a PC, an internal output relay is triggered. With this switching relay, electric consumers (i.e. electric heating rod in the process water tank of the heating, air-conditioning device or heat pump) can now be triggered. With the AD-PVO 2000, the energy is converted on site and not fed back into the public low-voltage network. Through the use of this device PV systems are optimized for their own consumption and relieves the public low-voltage grid. Additionally, the AD-PVO 2000 has an error message LED and an integral error message relay, via which error messages (i.e. permanent failure of the feeding) can be displayed or acoustically signalled outside the distributor cabinet. It is recommended to mount the AD-PVO 2000 directly after the counter of the energy supply in the distributor cabinet, as measuring should be carried out as close as possible to the feeding point. The device requires all three outer conductor voltages for its measurements and the zero conductor. The AD-PVO 2000 measures the current via three external split current current transformer, which can be mounted directly onto the 3 phases after the counter, therefore saving space (without separation). The Photovoltaic Optimiser acquires the self-generated supply energy from the measurement voltage L1. Due to its efficient switching network and its low power consumption, the AD-PVO 2000 generates only a negligible amount of warming and can therefore be lined up closely.

Heat pump control
SG-Ready
With the PV optimizer AD-PVO 2000 heat pumps can be signaled that enough PV surplus exists.
Thus, the heat pump can raise their storage or flow temperature and increase the personal consumption.
The optimizer is compatible with many SG-Ready (Smart Grid Ready) enabled heat pumps. The SG-Ready logo can be found on your heat pump.
The SG-ready interface is designed in in most cases as a contact input therefore, the overload relay of the PVO can be used easily as a signal for the temperature increase of the heat pump.
What is to be done at a SG-signal, it must be parameterized on the heat pump.
