Description
At 30 °C the transformer carries up to 9,856 kVA, so in the cool season the block can run above its 40 °C rating. Vector group Dy11y11 means a delta medium-voltage winding and two star-connected 0.8 kV windings, each feeding its own group of inverters. The MV and LV compartments are isolated from each other, so the 0.8 kV side is serviced without access to the 20–35 kV switchgear. IP54 protection and a −30 to +60 °C operating range suit open installation right on the PV field. The 6,058 × 2,896 × 2,438 mm footprint matches a 20-ft High Cube container, and at about 24 t it travels on a low-bed trailer and is set by crane on a prepared base. The smaller MVS6400-LV completes the line for lower-power blocks.
How to choose
Size the station by the total inverter power in the block and by the voltage of the line it connects to. The MVS8960-LV is built for a 0.8 kV input, which is the SG350HX output, and for a 20–35 kV grid, while a smaller block takes the MVS6400-LV. If the same site gets a BESS, the standard PowerTitan ST2236UX block has its own SC4000UD-MV PCS and a 4,000 kVA 0.8/33 kV transformer, so the storage usually connects through a separate bay.
