Grid tie gvfx3524 & fx2824 during power outage

Postby jnahanna1 on Mon Oct 15, 2012 9:25 am

I have a grid tied system for the last 3 years and love it with a single gvfx3524. I would like to be able to stack for 240V only during backup power outages (Normally the fx2824 would be turned off during grid times). I picked up a used fx2824 which works great however I can't seem to get it to stack to give me 240VAC to run the well with it doesn't want to sync with the master during off grid times.

What am I doing wrong here?

Thanks, Jim

I don't think you can stack a "G" inverter with a non G inverter. Try a forum search as I believe this question has been asked before.

Hello,

mtdoc is correct, you cannot mix "G" model inverters with non "G" models. Also we do not make a FX2824. The 2800 watt inverter is vented and works with a 12 volt battery bank (VFX2812). If it is a 24 volt inverter the output is either 2500 watts or 3500 watts (FX2524T or VFX3524, respectively).

If it is a 24 volt inverter we can convert the Off Grid inverter to a grid tied model. You will have to send it in to us for this update. Please call 360.618.4363 to arrange for the conversion if you want to go that route.

Thank you,

-Kurt
