XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off-grid photovoltaic systems, with optional display units (XDB1/XDS1/XDS2).
In order to maximize the energy harvest from PV arrays and simultaneously minimize the power loss within a wide range of operating conditions, the XTRA series apply an advanced smart algorithm which results in up to 30% higher efficient charging, compared to a conventional pulse width modulation PWM solar charge controller.
Xtra series controller has a limit protection function on charging current &charging power, as well as auto derating power operation at high temperatures; the above protection ensures the stability of the system even at exceeded rated PV power and over-temperature conditions.
Protection class IP32 and isolated RS485 communication port further improve the controller’s reliability under different application requirements. XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which effectively prolongs the lifespan of the battery and significantly improves the system performance.
It also has extensive electronic protection for overcharge, over-discharge, PV&battery reverse polarity and etc. to ensure the sustainability and durability of the off-grid solar system.
