Our Kimberley camper trailer came fitted with a Juta MPPT-20 20A solar charger. This charges the internal trailer batteries while at camp via an external anderson plug. Basically it sits between the solar panels and the batteries and manages the charge. Juta is a Chinese produced MPPT solar controller and commonly used in 4wd circles and it performed well throughout our trip in the Kimberley's.

While researching the Victron Energy battery capacity meter I can across their line of solar MPPT controllers and was very impressed so decided to install one in the camper trailer.
I decided upon the BlueSolar MPPT 100/30 and it just fitted in the space occupied by the existing Juta.

The BlueSolar range of solar charge controllers are high quality units featuring Ultra-fast Maximum Power Point Tracking and intelligent battery management. Features which especially appealed to me were the selectable lithium charge profile and the optional Bluetooth Smart dongle which enables a smartphone app to mange and monitor the controller operations.
The IOS/Android app allows the user to access live status info, see historical values as well as configure the controller.

It's very useful to be able to get a live feed of what the solar cells are doing and the history feature displays the total solar yield in Wh for each day and the max power generated.
If you in the market for a MPPT solar charge controllers wether it be for fixed or mobile 4wd use take a look at the Victron Energy range.
