- We want to shoot for a maximal array size
- We have a minimum voltage to meet per MPPT
We're continuing to use the AERL RaceMax 600B MPPTs- We are now considering the Nomura MPPTs
Requirements
| # | Title | User Story | Importance | Notes |
|---|---|---|---|---|
| 1 | Develop optimal array | We need to divide the array into sections to produce as much power as possible over the course of a day. | Must have | |
| 2 | Support supplementary modules | We might be allowed to bring an extra 1-2m^2 of PV cells for charging. This would be nice to support. | Optional | We are not allowed to have supplementary modules for ASC 2018. |
| 3 | Figure out how to interface with the MPPTs | It would be nice if we could read back the data from the MPPTs. | Optional | The AERL RaceMax 600B supports a meter module. See MPPT Interface Board for progress. |
| 4 | Isolation | We need to meet regulations requiring all conductors more than 200mm from the array are not energized in a safe state. | Must have | Look into embedding MPPTs into aerobody panels |
