The XTRA series (10A to 40A) features advanced Maximum Power Point Tracking (MPPT) for off-grid PV systems. It is designed according to international standards of the latest generation, reliability and safety. The function of limiting the charging power, the charging current and the automatic power reduction function ensure maximum stability when working with oversized PV modules (max. 1.5 times the rated power) and operating in a high-temperature environment. high temperature.
• MPPT efficiency above 99.5%
