If a Battery Energy Storage System (BESS) will be installed for customer self-use, it should be ensured the BESS does not have capability to export power to or back energize the distribution network connected in parallel with the main grid. Reference to Clause 306 of Supply Rules, application for Grid Connection is required for customer''s ...
INTRODUCTION. FAT refers to a Factory Acceptance Test. This is a way to ensure that equipment/systems being purchased meet the agreed upon design specifications. Ideally this happens before arriving at the customer''s plant, however, for complex systems with high integration, tests may need to be performed at the customer''s location.
In addition, there is a drop test in the test standards for energy storage batteries, which aims to simulate an accidental drop that may occur during battery installation and maintenance. In IEC 63056-2020 [ 71 ], drop tests are specified in detail for different weight classes, as listed in Table 3 .
