HMS-1600-4T

The HMS-1600 (MPN: HMS-1600-4T) from Hoymiles is the perfect micro inverter for your balcony power plant. This compact, lightweight device (weighing only 4.7 kg) is suitable for solar power generation with up to four solar panels, each with an output of 320 W to 540 W+. Just like all other micro inverters from Hoymiles, it is suitable for long operating hours and a wide range of PV module applications, as its start-up voltage is very low (only 22V) and the DC input range of the operating voltage (16-60V) is extremely wide.

Compared to the previous model from the HM series, the HMS-1600-4T offers greater safety for rooftop solar power plants thanks to its quick shutdown and isolated transformer. The new sub-1G wireless solution enables more stable communication with the Hoymiles Gateway DTU.

• Minimization of the effects of, for example, shading, dust, or aging through MPPT
• High-quality energy generation with high MPPT accuracy
• Optimal system reliability
• Peak efficiency of 96.7%
