<p>I second using the 48v to 12 v DC DC converter. I've had success
with that, and avoided the issues Jeremy mentioned.</p>

<div dir="ltr">I powered a MidNite LSOB transmitter from a Classic
AUX, though the receivers didn't work with the Classic. The
Classic is limited to 200ma output and the Tigo and APS
transmitters are rated at up to 800ma input, so it might
overload the Classic AUX output if they really do draw that
much.

</div>
<div>I tested an APS RSD system recently with a Classic and it
did not work well. I believe that the Tigo transmitter is very
similar since the APS devices say "licensed by Tigo" on them,
So, the Tigo RSD devices may not work well with a Classic
either. </div>

<div>What I recommended while at AEE was to use a 48VDC to 12VDC
converter to power the Tigo and APS transmitters. This works
well. Here's the one I recommended if it's still available: <a

moz-do-not-send="true">mean-well/ddr30l12</a> I never had
any negative feedback using this with a Sol-Ark and APS
devices. </div>
<div><br>
</div>
<div>With a Classic in the system I've had to use the FireRaptor
RSD devices. If you can get approval or have older modules,
you might be able to follow the FireRaptor instructions and
use 2 modules in series for each FireRaptor. You do still have
to have a way to disconnect the PV output circuit from the
Classic in order to make that circuit dead from the Classic
end of the circuit. I did that by putting an MNPV6-disco on
the power shed which disconnects the PV output circuit as well
as the 24VDC to the FireRaptors. And, I am powering my
FireRaptors at 15VDC and it works fine. </div>

anyone successfully used a MidNite Classic CC to power a Tigo
Rapid Shutdown Transmitter in an off grid setting ?
Specifically using the 12v Aux output to keep the PV circuits
alive instead of relying on the inverter AC output to do
this. <br>
<br>
Think of this scenario. Batteries reach LBCO, inverter shuts
OFF, no PV to re charge back to LBCI, no generator backup to
recharge batteries. <br>
