XTRA-N G3 BLE series controllers are based on a new design concept, featuring a Bluetooth module which allows you to read and write parameters via Apple and Android Smartphones. The controllers adopt the advanced MPPT control algorithm, improving the maximum power point (MPP) tracking and acting speed. By minimizing the MPP loss rate and time, the controllers can track the MPP quickly to obtain the maximum energy under any conditions. 

Independent voltage regulation, namely, the battery terminal of the controller can be connected to loads directly when there is no battery, this is a new added function. The Xtra Series are lithium batteries friendly, avoiding the instability output voltage caused by the internal protection of the lithium batteries. 

Low self-consumption design significantly reduces the static power consumption and extends system standby time. 

The Xtra Series perform well under the high temperature ensuring system stability. IP33 Ingress protection and isolated RS485 com port design improves the controllerís reliability to meet different application requirements. XTRA-N G3 BLE series adopts a three-stage charging mode, which effectively prolongs the battery's lifespan and improves performance. Comprehensive electronic protections, such as overcharge, over-discharge, PV & battery reverse polarity, etc., helps to protect the solar system components. This controller are widely used for RVs, Motorhomes, Caravans, Boats household systems, etc.
