Epever XTRA 40A 12/24V MPPT Solar Regulator

Epever XTRA MPPT Solar Charge Controller

The XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off-grid photovoltaic systems, with optional display unit. 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 etc. to ensure the sustainability and durability of the off-grid solar system.
