<div class="moz-cite-prefix">Depending on the original work, I'd
look at sealed batteries and leave it alone. I've done a bunch of
rewires, and you're really wasting the customer's money to rewire
80 watt modules. ( module J boxes are so 1990s....) Meanwhile
those 80 watt modules have decent resell value for small 12 v
systems, as does the Trace inverter.<br>
I found that Outbacks take about 480 w-hr/ day so that's a fair
bit of the array just to offset that.<br>
Small sealed battery bank, and let him play with a few backup
circuits in off grid mode might be OK. or offer him a new GT
system with a nice trade in allowance for the old gear.<br>
I did a rewire recently like this, and we reused the generator 3
way circuit selector. That lets them pick which circuits are on
or off the grid. I'm sure others here will have some good ideas I
haven't thought of too.<br>

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