Description

Buy the Victron Energy ArgoFET 200-3AC Battery Isolator (200A, 3 batteries) now for just $64.09 — a 54% discount off $140.25. It is the best-fit isolator for boats, RVs and multi-bank vehicles that need simultaneous charging of three battery banks from a single alternator.

Current Splitting & Total Rating

The 200-3AC handles up to 200A of alternator output across three battery banks. Current distribution follows each battery's acceptance; healthy, well-matched batteries receive charging in proportion to their needs while remaining electrically isolated from each other — the starter battery never drains into the accessory bank.

Frequently Asked Questions

Does the Victron ArgoFet 200-3AC split current equally between three batteries?

Not exactly — charging current flows to each bank according to its acceptance. The isolator keeps banks independent and delivers alternator output with minimal loss (<0.02V at low current).

What is the total current rating of the ArgoFet 200-3AC?

It is rated for 200A of alternator input across the three battery banks, with 12/24V auto-ranging.

Can I use it with a lithium house battery?

Yes, but the ArgoFet does not regulate charging. If your alternator regulation isn't lithium-safe, pair it with or replace it using a Victron Orion-Tr DC-DC charger.

What is the current price and are there promotions?

The sale price is $64.09 (reg. $140.25), a 54% discount. Use coupon OUTPOST12 for an additional 12% off.

Where can I buy it online?

Buy the ArgoFET 200-3AC here at PowerHaven Outpost with free shipping on orders over $45.

Three banks, zero drama

Starter, house, and bowthruster batteries all charging from one alternator with no voltage loss. Installation was clean and it's been flawless for a full season on my boat. Top quality as always from Victron.

Does what it promises

Voltage drop is essentially nil compared to my old diode splitter. Wiring took an afternoon because of the third output run. All three banks reach full charge on long runs now. Happy with the purchase.

Solid but heavy

Works exactly as described and my batteries charge properly. It's heavier and bulkier than I expected for the mounting space I had. Performance-wise no complaints at all.
