EPSolar XTRA2210N MPPT Solar Charge Controller 20A 12/24V Max. PV Voltage 100V

Description

EPEVER / EPSOLAR XTRA2210N
MPPT Solar Charge Controller 20A 12/24V Max. PV Voltage 100V
XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off-grid photovoltaic systems.
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 efficient 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 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 battery and significantly 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.
