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.

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.

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