no batteries on grid tie [RE-wrenches]

[Daryl Thayer]

hello to all again

Hello to all
I have a customer who wants a Bergey 1kW and grid tie.
 I have mostly done stand-alone and grid-tie with UPS
on a 24 or 48 volt battery set.  This Customer does
not want batteries.  

Can I use large capacitors?  Has anyone tried this? 
How large would the capacitors have to be?  Can I use
a FX series or other inverter?   It would seem the
faster the chop frequency of the inverter the smaller
the capacitors.  I think the SW uses a slower chop
than the FX ? so the FX would work better? 

If I am forced to use a battery, sealed AGM how small
could it be?  (I am concerned here myself because the
wind generator charge controller is not like an MX 60
with precise control.)  

Thanks again for all the help on my past questions.   

Daryl
