Frequently Asked Questions
What is the energize input on a Victron battery isolator?
The energize input provides a current-limited B+ voltage to the alternator's excite circuit when the engine run/stop switch is closed, ensuring the alternator starts charging.
How do I wire the alternator energize input?
Connect the energize input terminal to the ignition or run/stop switch that activates when the engine is on. This will power the alternator's field coil.
How do I wire the compensation diode?
The compensation diode connects between the isolated battery outputs and the alternator sense terminal, raising the alternator voltage slightly to overcome the diode drop.
Can I use the ArgoDiode for 12V and 24V systems?
The ArgoDiode 100-3AC is designed for 12V systems. For 24V, you would need a suitable model.
Where can I buy the Victron ArgoDiode 100-3AC at a discount?

It's okay
It gets the job done, but I expected a bit more for the price. The install was a bit fiddly with the wiring. But it's reliable so far.

Not for me
I had trouble with the energize input. It kept blowing fuses. Maybe I got a defective unit, but I'm not happy. I've switched to a different brand.
