This kit wires two SimpliPhi batteries into a BOSS-12 system using a matched bus bar and cable set, built for installers who need a clean, factory-fit parallel connection instead of a cut-to-length workaround.
SimpliPhi engineers bus bar kits to match specific battery counts and BOSS enclosure models, which matters more than it sounds. A bus bar sized for the wrong battery count changes current distribution across parallel strings, and that's a fitment issue, not a cosmetic one. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fitment & Requirements
- Configured for a 2-battery parallel setup.
- Designed for use with the SimpliPhi BOSS-12 system.
- SKU/Model: BB-2-12.
- NOT confirmed for use with BOSS enclosures sized for 3+ batteries — battery count mismatch changes bus bar current distribution. [NEEDS VERIFICATION]
- Wire gauge, ampacity limit, voltage rating, and terminal lug size are not specified in available manufacturer data. [NEEDS VERIFICATION]
Parallel bus bar connections are a common spot for loose terminal hardware to hide — a slightly under-torqued lug can run warm for months before it trips a fault code or, worse, becomes a hot spot under load. Re-check every lug on the bus bar with a digital torque wrench after the first charge/discharge cycle, once the hardware has had a chance to settle. Torque to the value listed in the BOSS-12 manual (see the Resources tab on this page — exact torque spec was not included in the data provided for this listing). Confirming torque against the manufacturer's published spec, rather than a generic hand-tight feel, is the standard NEC-minded installers hold themselves to.
Key Benefits
- Purpose-built for 2-battery BOSS-12 parallel wiring — no field-cutting or improvising cable lengths.
- Bus bar and wire sold together as a matched kit, reducing mismatch risk between components.
- Factory fitment designed around SimpliPhi's own enclosure geometry.
- Straightforward SKU-based ordering (BB-2-12) for repeat installs.
