9. Solar Panel Install
1. Sol-Ark 5K has 2 separate pairs of solar panel inputs. (Dual MPPT)
3. Max PV input:
6,500W(+/- 5%) per system (3,250W per MPPT) PV = 500Voc Max
Max Isc input per MPPT: 25A (self-limiting to 20A @450Voc/300Vmp or 18A @ 500Voc/400Vmp)
Note: Damage will occur if PV Voc > 550V.
4. Connect the strings of solar panels to the system as shown on pages 9/10.
5. Parallel strings per MPPT must be the same voltage, PV1A/B must be the same voltage if both are used (see
Fig. E). It is OK if panels for panels on the same MPPT to face different directions.
6. Panel frame grounding can be done to any ground in the home via 12AWG wire. Mounts usually bond
frames together, so only 1 ground wire is needed.
Note: Max Panels in Series (Rule of Thumb, always verify the string characteristics are within spec):
60 Cell: 10 72 Cell: 9 96 Cell: 6
