Outback Power Inverter Charger

Post by Usbe » Thu May 07, 2020 11:06 pm

Does anybody have any knowledge or experience with Outback Power inverter/chargers? I have been doing a lot of research and these seem to be pretty solid. I am looking at the VFX 2812. It is a ventilated 2800 watt 12V inverter with a 4 stage 125 amp charger w/ auto transfer. The specs are pretty impressive (90% efficiency) and from what I can read, the engineers are former Xantrex employees.

I have couple of VFX3648. I used them for about 6 years and they did very well, I just transition them to a new system and hope to get more years from them. My advice is to look at 48V inverters as you can size the batteries and cables more easily and less troubles down the road.

I dare say literally every one of us who uses Outback inverters have knowledge and experience with the built-in chargers. About 8% of the charging in my off-grid system is via the Inverter charger. Many others use the flexible grid-interactive modes for charging as well.

I don't know the provenance of the design engineers, but from experience and feedback on this forum, find the designs to be solid. Though the inverters achieve 90+% efficiency at higher output levels, I'd peg effective charging efficiency at closer to 80%.

Usbe,
Just to let you know, with exception of the M series (FX2012MT, VFX2812M, etc), the FX and VFX series inverters are discontinued from Outback product line-up.
I recommend you look at the FXR/VFXR series. VFXR2812A maybe a good fit for what you're looking.

Probably will be better to go with Radian, newer technology and works well for grid-tie or off-grid.

But the OP has a preference for a 12V system inverter ;-)

If he is looking at a 2800W inverter, for the cost difference and the advantages of using 24V or 48V, is better to advice him look for the higher voltage.
The only disadvantage i can see is the need of more batteries to get to 24v or 48v.
Most people using 12V get group 31 battery which is 105-110A. For more than 2000W inverter that is too small.
The best will be for him to tell us what are his present and future plans for the system.

Ages ago (circa 2004, before I switched to GVFX's) I had a VFX2812 that I had wired for a backup supply to my house critical loads. It worked fine but cannot sell to the grid (although at the time I had no solar panels or charge controller, so that wasn't a drawback for me). Also, it won't like anything but a high quality inverter-generator input (and the grid, of course).

I think if I post my question here I may find an answer.
How to set a lower cut off percentage in advanced settings when no numbers show up. I go to 75% battery by morning and my cut out is 80%. Can;t seem to reset it. as the numbers do not appear! If I could set it at say 65%...that would be so nice. Batteries are not filling up by nightfall this time of year.
