This is a real store run by Joel, the owner — not a call center. I design off-grid power systems and built this store's sizing tools. Tell me your setup (van, RV, cabin, or backup) and I'll tell you honestly what fits — before you spend a dollar.
Use the free Power Calculator to see exactly how much capacity your appliances need — no email required.
Open the Power Calculator →Blue Sea 1991 — PowerBar 1000 (12 × 3/8 Studs with Insulating Cover)
The upgrade pick for high-current bus bars in van, RV, and off-grid electrical systems. 1000A continuous rating — enough for the largest LiFePO4 banks and biggest inverter systems you'll ever build.
Key Features
- 12 × 3/8 threaded studs — more landing points than the PowerBar 8-stud
- 1000A continuous rating — future-proof for system expansion
- Clear insulating cover included — protects against accidental shorts, meets ABYC safety requirements
- Tin-plated copper construction
- Mounting hardware included
When to Pick This Over the 2107
Choose the PowerBar 1000 if you're running 300A+ of simultaneous load (big inverters, multiple DC chargers, large parallel battery banks) or if you want the insulating cover for code compliance. Overkill for basic builds; exactly right for serious ones.
