Specification of EPEVER MPPT XTRA Series( 10-40A)
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, XTRA series apply an advanced smart algorithm which results in up to 30% higher e cient charging,
compared to a conventional pulse width modulation (PWM) charge controller.Xtra series controller have limit protection function
on charging current &charging power, as well as auto derating power operation at high temperature; the above protection ensure
the stability of 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 di erent
application requirements.XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital
control circuit, which e ectively prolongs the lifespan of battery and signi cantly improve 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.
