<p>Yea, I almost always replace the on board controller on the
Anandas. On some I might keep a small original array on it, but I
always have large controller with 3 stage PWM going.<br>

<div>I have one of the first batch of Ananda with the Heinemann
breakers. I've used it with FX inverters and an XW inverter.
Mating it up with the FX was difficult, I ended up with an 8x8
gutter between them, and 2" offsets on both sides. Using the
conduit box on the XW was easy. I'd expect using the conduit
box on the Magnum would be straightforward as well. If I were
to try it with an FXR again I'd use an FW250 as a conduit box.
But definitely take out the Ananda charge controls and convert
to ones that match the new inverter. Unless you're adding more
solar that can do a good finish charge then the on/off control
for part of the array may be ok.</div>

Esteemed Wrenches;<br>

I have yet another customer whose 20+ yr old Trace SW
inverter has flown <br>
off to inverter Nirvana. I have replaced a few over the
years and never <br>
quite solved the quandary of whether to replace the entire
power board, <br>
or to retrofit a Magnum/ Outback in place of the SW, and
keep the old <br>
Trace DC enclosure. In this particular case, he has a pair
of SW 4024s <br>
on an old Ananda power center. I'm considering taking the
system to 48 v <br>
as well, since this will let us use the Magnum 4.4 kW
inverters. This <br>
however will also involve rewiring 20 yr old arrays of 50
and 75 watt <br>
modules......<br>
What is the consensus on the best replacement practices on
these legacy <br>
systems? I have several out there with the clock ticking
down. My <br>
current idea is to just keep the Ananda and use Magnum's
extension boxes <br>
to connect up the new MS 4448 inverters. Its a tough call:
I've <br>
replaced a few single SW installs and reused the Trace DC
enclosure, and <br>
cursed working in those tiny boxes. In other cases, I've
put up a whole <br>
new system, but wondered if that was over kill too. It
seems to be a <br>
case of more field installation hours vs more equipment
costs.<br>
<br>
Sure be handy, if someone made an SW replacement kit, there
are still a <br>
bunch of them out there.<br>
<br>
As always, thanks for all your comments and ideas,<br>
