AD-PVO 3000 GT

Description

The photovoltaics optimiser AD-PVO 3000 monitors the feed of solar energy at the main connection of a building. The analogue outlput (0...20 mA, 4...20 mA, 0...10 V or 2...10 V) can be parameterized freely, therefore, the electric heating rods can be controlled via a thyristor power controller. The AD-PVO 3000 regulates the heating rod output in such a way, that the feed is kept at zero. This is realised with an integral software PI regulator, which adjusts the power at the heating rod up to its maximum value of the feed-in power. With this device, the energy is optimally implemented on site and is not fed back into the public low-voltage network. This way, the PC units are optimised for personal consumption and the public network is relieved. Additionally, the AD-PVO 3000 has an error message LED and an integral error message relay, via which error messages (i.e. permanent failure of the in-feed) can be indicated or acoustically signalled outside the distribution cabinet. It is recommended to mount the AD-PVO 3000 directly after the energy-counter of the energy supply in the distribution cabinet, as measuring is to be carried as close as possible to the in-feed point. The device requires for its measuring all three external phase voltages and the neutral conductor. The AD-PVO 3000 measures the current via three external split core current transformer, which can be mounted space-saving (without separation) directly on the 3 phases after the counter. The photovoltaic optimizer receives the personal consumption energy from the measuring voltage L1.

EMC-appropriate assembly
When assembling the AD-PVO 3000, including a thyristor power controller, please observe the regional and/or country specific regulations of the network operator.
When operating great loads with leading phase-angle or trailing phase-angle, considerable network reaction can be expected to the current intake, which is not sinusoidal.
The regulations for operation of heat generators with leading phase-angle or trailing phase-angle depend on the network operator. In case of doubt please contact the network operator.
The erector of the unit must, if necessary, reduce the electromagnetic emission with suitable chokes or suppressor filters.
Chokes reduce the current-dependent network reactions and effect an improvement of the power factor. The current harmonics content is reduced and the network quality is improved.
Network filter serve mainly the protection from high-frequency disturbance variables, which are emitted, conductor bound, via the network cable or through the air.
Shielding measures may be necessary to reduce the emission. The conductor between thyristor and load should be shielded.
The shield must be earthed with low impedance or over a large surface, however, it must not replace the PE conductor!
