Hub10 vs. Hub10.3

Postby Mike Curran on Sat Apr 01, 2017 11:51 am

I'm in the process of expanding my system and will need to swap out my Hub4 for a Hub10, or 10.3. I can buy a used Hub10 cheaper than a 10.3 - does anyone know what is the difference? Any recommendations would be welcome. Thanks.

H Mike,

The HUB10.3 allows our new FXR inverter models to sub-phase stack. This new method allows the inverters to stack in 3-phase, split phase and single phase regardless of the model. Unlike older GVFX's only allowed 2 inverters in a split phase configuration and would not strack in 3-phase to name a few.
For further information check out page 39 of the operators manual: http://www.outbackpower.com/downloads/d ... erator.pdf

What inverter models are you trying to stack and configuration?

2 × GVFX3524. I ordered the 10.3, got a fairly good price for a new one.

Right now with my Hub4 my two inverters are "classic stacked", with one designated as master and the other as slave (p. 24 of the GVFX manual, "Stacking Instructions"). Between them they power a 240VAC well pump, plus each has independent 120VAC loads - a sump pump, fridge, oil-fired hot water heater, hydronic heating pumps, etc.

From the Hub10.3 manual (p. 40) you referenced Jorge, it looks like I should set up my inverters for "Series stacking". Is that possible with my inverters, or should I just stick with the arrangement I have now? Or is it the same thing?

Thanks!

Classic stacking is the correct configuration for two GVFX's. Only two may be stacked this way. No other inverters may be added to the same system.
What other components are you trying to add?

Flexmax80 charge controller with 1800 watts of ALEO modules (2×3×300W). Seems a shame I had to shell out 2.5 Franklins just to add one device to the comm system.
