[RE-wrenches] Number of Controllers

[Larry Crutcher, Starlight Solar Power Systems]

Colin,

The IPN Network charge controllers from Blue Sky Energy can be configured as Master & Slave so ALL controllers work together. 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.

Wrenches,
What considerations are there for the number of charge controllers that can be in a stand-alone system with a single battery bank?  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?
