What is the Victron Energy ARG120201020R used for?

The Victron Energy ARG120201020R is a 120A Argodiode battery isolator designed to charge two batteries simultaneously from a single alternator while preventing discharge between them.

How does an Argodiode battery isolator work?

An Argodiode isolator uses high-efficiency diodes to direct current from the alternator to multiple batteries while keeping them electrically separated, preventing cross-discharge.

Can the Victron ARG120201020R charge two batteries at the same time?

Yes, it efficiently charges two batteries simultaneously, ensuring the starter battery remains protected when auxiliary loads are in use.

Does the Victron Argodiode cause voltage drop?

The unit uses Schottky diodes, resulting in a very low voltage drop—approximately 0.3V at low current and up to 0.45V at maximum rated output.

What is the purpose of the compensation diode in this isolator?

The compensation diode slightly increases the alternator output voltage to offset diode-related voltage loss, ensuring optimal battery charging performance.

Victron Energy ARG120201020R

The Victron Argodiode 120-2AC battery isolator efficiently charges two batteries simultaneously from a single alternator, ensuring no discharge between batteries. With Schottky diodes, it minimizes voltage drop for optimal performance, making it an essential component for maintaining battery health in automotive and marine applications.

Product Features

Simultaneous Dual-Battery Charging

This isolator allows for the efficient charging of two batteries at the same time using a single alternator, safeguarding the starter battery from being depleted when the accessory battery is in use.

Reduced Voltage Drop

Incorporating advanced Schottky diodes, the product ensures a minimal voltage drop, enhancing charging efficiency. At low current, the drop is around 0.3 V, increasing only slightly to 0.45 V at rated output.

Compensation Diode Inclusion

Equipped with a compensation diode, this feature slightly boosts alternator output voltage, counteracting the small voltage drop through the isolator for maximum charge efficiency.

Alternator Energize Input

This isolator includes an energize input for alternators needing a DC signal to start. This feature ensures reliable alternator performance even when the isolator is in place.

Sturdy and Adaptable Design

Built with robust materials and designed for straightforward installation, it fits well in both automotive and marine electrical systems, promoting extended battery longevity and performance.

How It Works

The Argo Diode Isolator effectively channels power from a single alternator to multiple batteries, without linking them together. It cleverly uses diodes to maintain battery separation, preventing cross-discharge and providing stable, reliable power to all connected batteries.

Diode Technology

This component plays a crucial role by allowing current to flow in a single direction, ensuring simultaneous charging while keeping the batteries isolated.

Voltage Compensation

Utilizes a special compensation diode that adjusts the alternator voltage output to maintain optimal charging levels by negating diode-induced voltage drops.

Energize Feature

An integrated built-in energize circuit that triggers the alternator to commence charging, ensuring compatibility and functionality with modern alternators requiring a DC signal.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
