Kadant Energy's fifth-generation GTMI series communication products adopt a waterproof streamlined design, which can better provide heat dissipation for the equipment. The built-in maximum power point tracking engine (MPPT) can better capture the changes in light, even in rainy weather, and it can capture and collect sunlight to the greatest extent. The inverter is compatible with a variety of conventional solar panels with an open circuit voltage of 22~60V, and through technical means, the panel can exert its best performance.
