Hi... I'm planning to add some solar to our van that will only get used a handful of times a year. Typically we don't camp longer than our house battery allows, but we have a couple trips planned where solar would be preferred to keep things topped off and the fridge running. I'm planning to add a SmartSolar MPPT 75V/15A controller to an existing setup and have it basically idle most of it's life. I anticipiate that I'll get some useful data from the load side of things. Some questions:
* Does it matter if the solar panels are only occationally plugged in?
* When we're not using the van, it gets plugged into shore power and there is a trickle charger that maintains the house and primary battery. Will that confuse/affect the MPPT at all?
* Same question for the battery combiner that opens up when the van is running to charge both primary and house battery.
Here's what the current setup looks like:
And what I was thinking after adding the MPPT:
And concerns here?
Thanks in advance
