I just purchased a used 2.4 kw. system that included this type of controller. I plan to series, 4 panels in a circuit (5 pairs,20-120 watt panels) and charge 8-L16 Trojan batteries..

One of my installs was a Rangemaster ~300 ft. away from the house. I fed audio/power to it through Cat-5. I converted my 12 volts up to 24 volts to overcome wire losses. The Rangemaster only drew ~120mA. My audio level was earphone level from a small battery powered mixer. It worked fine. No problems feeding the Rangemaster with 24 v.d.c.
Had another set up using a SStran. Put a FM radio rcvr inside the weatherproof box to get the tx audio for the AM. Broadcasted on FM from the house with a DataKit FM xmtr. (stl) The power supply for the SStran was totally seperate from the house supply. (No wires between the house and xmtr) 96 watts of panel, charge controller and a small marine battery @ 12 v.d.c. (overkill but..) The FM rcvr in the box with the SStran needed 6 v.d.c. I used an LM7806 to power that. Worked fine.. Last long time.. 😉
My love chunks just bought me a Ramsey 25B for my birthday! I plan on broadcasting XM all around the house. I have a seperate solar system built for my porch and outdoor lighting. I have a kick butt stereo system built-in to the porch. Now I can easily listen to my Deep Tracks any time I wanna.. Gotta luv ‘er..
