The Epever MPPT-XTRA-4210N G3 charge controller features a maximum power point tracking algorithm with efficiency exceeding 99.5%. The extremely fast response speed ensures that the system instantly adapts to changes in sunlight, maximizing the performance of the photovoltaic units. It supports a nominal charging current of 40A with a nominal power of 520W for 12V systems and 1040W for 24V systems. At the same time, it manages a maximum PV open circuit voltage of up to 100V, allowing flexibility in the configuration of solar panels and minimizing transmission losses.

The device offers full compatibility with Lithium batteries (such as LFP4S or LFP8S without BMS communication), GEL, AGM, and open-type batteries. It features adjustable three-stage charging, automatic temperature compensation for lead batteries, and stable automatic activation operation for lithium batteries. One of its most important advantages is the constant voltage output function, which allows the photovoltaic system to directly supply current to the load during sunlight even without using a battery, significantly expanding its application possibilities.

Equipped with an RS485 communication interface, the regulator allows connection with optional Wi-Fi or 4G units for remote monitoring and configuration via the EPEVER APP. Designed for high durability, it features IP33 waterproof protection, extremely low power consumption below 10mA, and optimized electromagnetic compatibility (EMC). Additionally, it incorporates a full range of electronic protections against short circuit, overload, overcharge, discharge, and reverse polarity on both the panel and battery sides.
