Explanations
Sunways Solar Inverters of series NT 10000 are Solar Inverters that inject in three-phases and are not capable of isolated opera-
tion. The NT 10000 consists of three single-phase inverters with a three-phase voltage monitoring system that inject into different
phases. These integrated inverters control their phase angle independently of each other. They are equipped with a voltage-
monitoring system and a three-phase monitoring system for any reduction of the linked voltage, in accordance with section 2.4.2
of the VDEW directive (4th edition 2001). Therefore, no always accessible isolating point is required (see section 2.1.2 Schaltstelle
mit Trennfunktion [Control Point with Disconnection Function]). A routine test is carried out with each device to make sure the
turn-off values of the three-phase voltage reduction protection are maintained. Subject to changes. Currently valid edition availa-
ble at request.
