I'm in process of configuring my system. I'm going with24v lifepo. Multiplus 24/3000 seems like it will manage my needs. The mppt 75/15 also seems like a good fit, but a little confused. 1) The spec says 75v 15A. That would = 1125W. But the spec says it can handle only 400w panels. Is that correct?
2) I want to use two smaller mppt because I anticipate more shade on panels in front of boat. Will Bluetooth work for both mppt controllers?
The power handling is battery Voltage x maximum charge current. So 24x15 = 360W
When the battery reaches full charge it will be more like 28V, so 28x15 = 420W.
The Smarsolar range of charge controllers have Bluetooth built in.
I'm not sure what you mean by "Will Bluetooth work for both MPPT controllers"?
2) they recently allowed two MPPTs to sync so you would join both MPPTs on a bluetooth network and then you can sync them so that you can see the combined charging of both MPPTs and they sync bulk/float etc.
You will still see both controllers in the app.
