2000W Inverter Cable
2000W Inverter Cable
For 2000W inverters, the current draw is too high to run through an Anderson plug — so this cable bolts straight to your battery terminals on both ends. Ring terminals at the battery, ring terminals at the inverter, with a 250A inline fuse already on the line.
- Ring terminals on both ends: Bolts straight to your battery posts and your inverter's input studs — no connectors in the middle to overheat or fail under sustained load.
- 250A inline fuse, pre-installed: Sized for the 170–180A continuous draw of a 2000W inverter, with headroom for the surges when motors or compressors start. If something goes wrong, the fuse blows before your wiring or battery does.
- Heavy-duty 2 AWG cable: Stepped up from 4 AWG to handle the higher current without heating up or sagging voltage under load.
- Direct to battery, not via the Power Module: At 2000W, the current is too high to run reliably through any Anderson plug. Going straight to the battery is the safest and most efficient path.
- For 2000W inverters only: If your inverter is 1000W, use the 1000W Plug & Play Inverter Cable instead — Anderson plug, lower fuse, easier install.
This is the more involved install of the two inverter cables — but only because the inverter itself is bigger. You'll need a spanner to loosen and re-tighten your battery terminals. That's the only extra skill required.

Common questions
Why doesn't this work with the Power Module like the 1000W cable?
The current draw of a 2000W inverter is around 170–180A continuous, with peaks higher. The 175A Anderson plug on the Power Module is rated right at that limit — and Anderson connections at sustained high amperage can heat up and degrade over time. Going direct to the battery is the safer, more efficient path for 2000W loads.
What size ring terminals are on this cable?
The battery-side rings are sized for the standard battery terminal post (M8 / 5/16"). The inverter-side rings are sized for M8 inverter input studs — the most common size on 2000W inverters from Renogy, Projecta, GIANDEL, Redarc and similar. If yours is different, get in touch.
Why a 250A fuse for a 2000W inverter?
A 2000W inverter pulls around 170–180A continuous, with surges to 220–240A when loads start (motors, compressors). 250A gives you headroom for those surges without nuisance-blowing, while still protecting your wiring and battery if something seriously fails.
Can I install this myself?
Yes — it's two ring terminals bolted onto your battery and two onto your inverter. You'll need a spanner or socket wrench to loosen and re-tighten the battery posts. No crimping, no wiring decisions. Disconnect the negative battery terminal first as a safety step, work with the inverter switched off, and you're good.
Is it safe to connect a 2000W inverter direct to my dual battery?
Yes, when the cable is the right gauge and the fuse is right-sized for the load — which is exactly what this cable is built for. Your dual battery system handles the discharge; the inline fuse handles any fault downstream.
