• Isolate the inverter from all power sources before working on it. Isolating the PVS300 inverter from external power sources Isolating the PVS300 inverter from external power sources Turn off the main disconnector and circuit breaker(s) at the AC distribution board.
• Never ground the DC+ or DC- live conductors. Notes: • PVS300 is a transformerless inverter; the DC side and AC grid are not galvanically separated. Therefore PVS300 must not be used with solar modules which require DC+ or DC- conductor grounding.
• The inverter is not field repairable. Never attempt to repair a malfunctioning unit; contact your supplier, local ABB representative or Authorized Service Center for a replacement. • Protect the inverter so that dust from drilling cannot enter it during installation.

Maximum power point tracking is a software function which operates the inverter automatically at the optimal operation point of connected solar modules. PVS300-TL inverters have one MPP tracker. Residual current detection In accordance with VDE0126-1-1; the inverter has a DC and AC sensitive residual current monitoring unit (RCMU) which measures and sums the currents of L and N conductors.
The I2I link enables inverters to share monitored information. Three phase configuration With help of I2I link, three PVS300 inverters can be connected to and monitoring three separate phases to form a solar system which has three phase AC output and grid monitoring. In this configuration the power output difference between phases is limited to 4.6kW.
You find the type designation on the type designation label attached to the inverter. The first digits from the left express the basic configuration, for example PVS300-TL-3300W-2. The final digits are reserved for optional selections. The type designation selections are described below.
The remote control unit terminal is used together with accessory kit PVS-APK-F. I2I link terminal X3 The I2I link terminal is used to establish communication between three PVS300 inverters, each feeding into separate phases. This communication is the basis for 3-phase monitoring function and enables 3- phase solar generator connection to the grid.
Operation basics and hardware description 31 Clamp connections for cable shields Clamp connections for the cables shields are used to equalise the control cable shields and inverter control board potential. RJ45 data connector X6 RJ45 (8p8c) connector is used for connecting the control unit or wireless communication (part of PVS-APK-M) kit to the inverter’s control board.
