Part 3 of 7 – Balance of System equipment selection

1. Question

Question 1

a) BESS location and mounting method

Determine the best location for the battery and the mounting method.

2. Question

Question 2

State your reasoning for location and mounting method. You may also refer to clause 4.2.2.2 in AS/NZS 5139.

This response will be reviewed and graded after submission.

3. Question

Question 3

b) Sizing and selection of AC protection devices

Select and size the AC protection device/s for the BESS. Refer to the BESS datasheet (provided in component specification folder) and installation manual (source this online).

Fill in the blank 1 of 1 A

4. Question

Question 4

Please provide your working and/or reasoning.

This response will be reviewed and graded after submission.

5. Question

Question 5

c) Sizing and selection of AC cables

Select and size the AC cables from the battery to the gateway/MSB using the Vc method from AS/NZS 3008.1.1:2017.

For CCC considerations, assume the wiring method will be enclosed – wiring enclosure in air, 2core sheathed cabling.
Begin by selecting the cable type you wish to use, both are multicore circular copper cable (Vc).
Answer with 2 decimal places.

Question 6

Please provide your working.

This response will be reviewed and graded after submission.

7. Question

Question 7

vi) What is the minimum area of the AC cable based on the minimum Vc calculated above assuming a multicore circular copper conductor was used?

(Hint: Assume max power factor and don’t forget to convert Vc to three phase before looking at AS/NZS 3008.1.1:2017)
