[aprssig] [off-topic] Are solar charge controllers a safe power tap?

This might be a little off-topic, but I'm having difficulty finding a wiring path in my RV to get direct battery power for my rigs (especially my remote monitoring APRS project), and wanted to bounce an idea off the collected wisdom.
The battery compartment on my motor home is pretty isolated from the passenger areas, so I was looking for an easier/safer place to tap. I had had a solar power system added to the motor home, and the charge controller (a Blue Sky MPPT controller) is mounted in the inverter compartment (5 feet from the battery compartment) with 2/0 cable linking the charge controller output to the coach battery terminals. Since it is much easier to get to the charge controller than to the batteries (in terms of running more cable), I was wondering if it would work to parallel off the charge controller output, or whether that would inject too much noise into the radios.
Any advice welcome.
