New Guy VFX2812M

Post by allankay » Tue Jun 16, 2020 7:48 am

I bought a boat with this Outback system including the Mate2 remote. What I am having great difficulty with is simply viewing the current settings amongst the many viewing options. Specifically, I need to see how the battery AmpHours Capacity is setup now, by the previous owner(s). It was easy to get this info on a Link 1000 without risk of changing settings. My house bank is six 6 volts and should be 600 amp hours capacity at 12vdc. Please point me in the right direction and I will do another hour on the programming manual. Thank you.

I think you can specify the size of the battery in the mate only if you have the FNDC.

What is FNDC please?

Manuals left on the boat describe configuration of the battery bank size.

FNDC - FLEXNet DC is Outback's battery monitor. It tracks current flow into and out of the battery and uses configuration data to derive battery state of charge.

It is the only piece of Outback gear that "knows about" battery capacity, so is the only one configured with battery bank size information.

Do you have any pictures of the Outback installation? Also a picture of the Mate home status screen?

Pictures requested. Is the Home screen this one?

The pictures show the Inverter and a Mate 2 system controller.

You may already have it, but attached is a digital copy of the Mate/Mate 2 installation manual.

The battery state of charge screens can be accessed by the navigation outlined starting on page 28. If there is no FNDC in the system, I'd expect NULL values here.

If there are values as shown, then the FNDC is wired into the system (and tucked away somewhere out of sight perhaps.)

If not installed, an FNDC could be added, integrating neatly with the Mate and FX Inverter.

Alternately, another, stand-alone battery monitor could be installed.

In any event, a quality battery monitor that works by "current counting" is important for good battery maintenance. The voltmeter type monitors are useless for accurately monitoring a battery under load.

Can you have a look in the area where your battery bank is to see if there is a shunt on your battery bank's negative cable (see picture below)?
A shunt is used to "count" the amps going in or out of the battery bank and is the only real way you can have any idea as to how "full" your battery bank is.

Good news! Your help caused me to evaluate things differently and the Outback charges the house bank while E-meter displays info I was after (and is set for 600 amp-hrs capacity). All is well except the bank is from 2013 - expense close at hand.

Perhaps I was overjoyed too soon. Yes, I have the E-Meter and there can set capacity of the house bank and battery type. No, the system does not have a shunt as in the posted photo above to monitor current. However, the E-Meter does display amps, amp-hours, voltage, and time available. Must get current flow info from somewhere that I have not figured out yet.

Question - Outback system charges the house batteries but no controller setting is available for AGM, Gel, or Lead Acid type. Other chargers I have offer a selector switch for battery type, and bulk, etc.

Perhaps I am to set this in the voltage and float settings and have to know my battery parameters?

Can someone please tell me why this Battery Type setting is not needed on the Outback charging?

Thank you

The Battery Type settings on most chargers set a generic profile that is more or less in the ballpark for the particular battery type. However, close to the target, while good for hand grenades and horse shoes, isn't optimum for battery charging. The Outback devices allow each aspect of the charge cycle to be specifically tuned per the battery manufacturer's specifications.

If the spec sheet for the battery is at hand, the charging parameters should be published on it. Those values should be used to program the chargers.

If the battery is not identifiable as to model and manufacturer, if the general type is known (flooded lead acid, sealed lead acid (agm), gel lead acid, etc., generic charging parameters can be entered. Let us know what type the battery is, and we can suggest some parameters to try.

Thank you for offering to help set this up when I purchase new batteries. At this time, all is flooded lead acid which I believe is a generic setup on the charger.
