This is a positive/negative bus bar pair for connecting multiple Simpliphi battery terminals into a single distribution point. It's built for anyone paralleling more than one Simpliphi battery and needing a clean, code-legal way to combine terminals.
Bus bars are a small part with an outsized job: every amp your battery bank pushes travels through this metal before it reaches your inverter. Simpliphi built this set specifically for their terminal geometry, which matters more than it sounds like it should — a bus bar that doesn't seat flush on the terminal post creates resistance, heat, and eventually a fault you'll be chasing at 2am. 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.
- Two-terminal configuration: one positive bar, one negative bar (sold as a set)
- Manufacturer: Simpliphi, model BB-2
- Designed for connecting terminal points across multiple Simpliphi batteries
- Gauge, ampacity limit, and voltage rating are not published in the source data for this listing — treat as [NEEDS VERIFICATION] until confirmed against the Simpliphi datasheet
- NOT confirmed compatible with non-Simpliphi battery terminal layouts
- NOT rated for any ampacity or voltage beyond what Simpliphi documentation specifies — do not assume a rating not listed here
- Matched to Simpliphi terminal geometry — no adapter plates or filing required
- Set includes both polarities, so you don't have to source positive and negative separately
- Solid bar construction avoids the flex-fatigue issues of cable jumpers used for the same purpose
- Purpose-built part number (BB-2) traceable to a single Simpliphi application

FAQ
What size are the terminal lugs on this bus bar set?
Terminal lug size is not specified in manufacturer data provided for this listing. [NEEDS VERIFICATION]
Is this bus bar set rated for 48V systems?
Voltage rating is not specified in the manufacturer data provided for this listing. [NEEDS VERIFICATION]
Will this bus bar work with non-Simpliphi batteries?
This set is designed around Simpliphi terminal spacing and hardware. It is not confirmed to fit other brands, and mismatched terminal footprints can create loose or unsafe connections. Don't mix brands without confirming physical fitment first.
How many batteries can I connect with one bus bar set?
This set has two terminals (positive and negative), meaning it links two connection points per bar. Manufacturer data does not specify a maximum battery bank size for this part. [NEEDS VERIFICATION]
