Product Description
Interconnecting busbars for paralleling two or three PHI batteries (SKU numbers BB-2-12 and BB-3-12, respectively) may be purchased. All batteries contained within the PHI battery bank must be identically grouped (i.e. do not use both the BB-2-12 and BB-3-12 products within the same PHI battery bank). This presents limitations when wiring fewer than 12 PHI batteries in the BOSS.12 enclosure.
| Number of PHI Batteries | Recommendation |
| 12 | Order 4 x BB-3-12 busbar sets (4 positive, 4 negative) and 8 total 45”-long 2/0 Arctic Ultraflex Blue® cables with 3/8” lugs included (4 positive, 4 negative). |
| 11 | Not supported, consider purchasing additional battery. |
| 10 | Not supported, consider purchasing additional batteries. |
| 9 | Order 3 x BB-3-12 busbar sets (3 positive, 3 negative) and 6 total 45”-long 2/0 Arctic Ultraflex Blue® cables with 3/8” lugs included (3 positive, 3 negative). |
| 8 | Order 4 x BB-2-12 busbar sets (4 positive, 4 negative) and 8 total 45”-long 2/0 Arctic Ultraflex Blue® cables with 3/8” lugs included (4 positive, 4 negative). |
| 7 | Not supported, consider purchasing additional battery. |
| 6 or fewer | Use the BOSS.6 or follow BOSS.6 wiring guidance if considering expansion beyond 6 batteries in the future. |
Terminal block-to-inverter cables are included with the BOSS.12 purchase. SimpliPhi typically uses two (one positive, one negative), 96”-long 4/0 Arctic Ultraflex Blue® cables with 3/8” lugs included (one lug on each end of the cable), for connecting between the terminal block and the inverter’s DC busbars or plates.
Note: Arctic Ultraflex Blue® cables are rated according to the specifications listed at this link: http://www.polarwire.com/properties-specs.pdf.
- Arctic Ultraflex Blue® 2/0 AWG cable has a 325 Ampacity rating at 86°F (30°C)
- Arctic Ultraflex Blue® 4/0 AWG cable has a 440 Ampacity rating at 86°F (30°C)
CAUTION: The two (one positive, one negative) 4/0 AWG Arctic Ultraflex Blue cables (each rated at 440A) typically sold with the BOSS.12 will not suffice when taking advantage of the FULL instantaneous continuous current output of all 12 PHI batteries (450ADC combined).
