With up to 8 controllers on the network, you can have multiple arrays and orintations. Their new Duo model will function as hydro or wind diversion control. AND, each controller has a fully programmable lighting control! Sounds like this is the controller to meet all your requests. We have sold hundreds and I highly recommend them.<br><div>

If one uses MPPT controllers, then one would want (I think) a different controller for different module orientations. That is, if one had a couple modules at one azimuth/tilt angle you would have a controller for that, and another controller for a module at a different azimuth/tilt angle. Also, I can see having a controller to turn on yard lights (Morningstar makes one, although it is not an MPPT type and is of limited capacity). Could also one have a controller for diversion loads? And also a controller for a wind generator? So I can see where a stand-alone system might have 4 or maybe even more controllers, all tied into the same battery bank. Are there any considerations for a system like this? For instance, do the setpoints for all controllers need to match?<br>Colin Vogt<br>_______________________________________________<br></div></div></div></body></html>
