Given the following information:
- mppt controller
- panels rated Vmp = 36v (parallel)
- measured panel voltage (Vpanel) every 4 minutes
at what time (roughly) did the system reach Absorption voltage (Vabs)?
| Time | Vpanel |
| 0912 | 36.37v |
| 0916 | 35.21v |
| 0920 | 36.16v |
| 0924 | 36.57v |
| 0928 | 36.82v |
| 0932 | 36.30v |
| 0936 | 35.67v |
| 0940 | 35.97v |
| 0944 | 37.14v |
| 0948 | 37.89v |
| 0952 | 38.09v |
