Question 1

Can controller be installed in battery compartment (somewhat limited in space). RV application, 2-6volt batteries, 1-100 watt panel.

Accepted Answer

Yes, as long as installation is not too close to batteries and the area is vented to avoid potential gassing / corrosion issues. And to allow for proper temperature sensing if the unit has only a built in sensor the controller should be is the same area as the batteries.

Question 2

Does this unit alternate voltage based on battery temperature?

Accepted Answer

The charger will compensate for temperature based on it's internal sensor, essentially gauging the local environment's temperature.  An option Smart Battery Sense can be attached to the battery for true battery temperature. Those are new and in short supply, but should be fully available by the end of June, 2018.

Question 3

what is the difference between smart solar and blue solar?

Accepted Answer

The single difference between them is that the SmartSolar MPPTs have Bluetooth built-in so that you can monitor and configure them through the VictronConnect smartphone app. The BlueSolar MPPTs do *not* have the Bluetooth built-in; you can use a VE.Direct to Bluetooth Dongle to achieve the same functionality, but the cost of a SmartSolar ends up a little less (typically) than a BlueSolar MPPT +a VE.Direct to Bluetooth Dongle, so it usually makes more sense to order the SmartSolar. If you're not planning on monitoring the MPPT or changing any of the settings, however, a BlueSolar will be just fine, as the actual circuitry is virtually identical.

Question 4

Will this charger charge uphill? Meaning if I have a48v battery, do I need 52v from the solar panel just to start the charger?

Accepted Answer

No, this charge controller will not charge 'uphill'.  You would need enough panels in series to have more than 48V.  If you absolutely need to charge 'uphill', look at Genasun.
