Hi Dana,
If the Trace model is SW, it will not be approved for selling if it was 
manufactured prior to 2002 (non-GTI model). If the batteries need to be 
replaced, the added expense may be considerable depending on the size of 
the bank. I guess it depends if the customer really wants backup. You may 
want to consider reconfiguring the array in series and go with a grid 
interactive inverter, such as the Conext TX2800, which will work fine with 
a 1.9kW array (24 in series). Other replies to this post indicate the 
array is not easily accessible, which can present it's own set of issues. 
I guess it boils down to what the customer wants. You can always sell the 
Trace inverter to someone off grid and use the proceeds toward a new 
grid-tie inverter.

I have a client eat has a 24 - Solarex  SX 80 PV module system that was 
off grid, Trace inverter, APT Power panel and an very aged L-16 battery 
bank. 
The utility came in and he wants to go grid tie. It is or was only 960 
watt originally. I realize that an array rewire is in order and it may 
only be a 1 KW system but he is interested in getting the equipment 
upgraded.
Has anyone done a grid tie with such a small array and with modules this 
old?
Any thoughts on installing sealed batteries and leaving it alone?
