The core technology of the Trace chargers is based on the multiphase synchronous rectification technology (MSRT) and efficient MPPT algorithm that tracks the maximum power point of the solar panels with great accuracy. The dual-core processor ensures fast response time to sudden changes (sun, cloud, shadowing). That improves the conversion efficiency from the captured solar power to the energy that is stored in the batteries. Tracking the current and voltage of the PV array is critical to obtain the maximum energy yield.

XTRA(10A~40A) series is an advanced maximum power point tracking (MPPT) charge controller for off-grid photovoltaic systems, with optional display units.

(XDB1/XDS1/XDS2). It is designed according to the international standard with higher quality, reliability, and safety. The limitation function of the charging power, charging current, and automatic power reduction function fully ensure stability when working with oversized PV modules(max.1.5 times of rated power) and operating under a high-temperature environment.
