Description
The converter steps the battery voltage up or down from the 500–1500 V range to the level of the DC bus of the solar field, so the battery and the panels share one central inverter. The three-level buck-boost topology reduces switching losses, and the maximum efficiency reaches 99 %. The maximum current of 360 A limits the power at low battery voltage, so at the start of the range the converter transfers less than its rating. The IP66 / NEMA 3R enclosure is designed for outdoor installation next to battery containers. The DC-coupling scheme makes it possible to charge the battery with energy that the inverter would otherwise clip because of the output power limit.
How to choose
This route is chosen when the solar plant already has 3Power C Series or C Series Plus central inverters with a 1500 V input and a storage needs to be added without a new grid connection. The number of converters is calculated from the battery power, based on the 432 kW rating at 1230 V and the 360 A current limit. If the battery has a separate connection to the AC grid, a three-phase battery inverter is more appropriate.
