About the Deye 400 W Single-Phase Micro Solar Inverter SUN-M40G4-EU-Q0-I
Rated at 400 W of AC output active power, the Deye SUN-M40G4-EU-Q0-I is a single-phase micro-inverter in the Micro (M) range that converts the output of one photovoltaic module on the roof itself. Its single tracker takes a panel of 210 W to 560 W and up to 560 W of PV input power, which covers almost every full-size residential module now sold, and it wakes at a 20 V startup voltage inside a 25 V to 55 V tracking window. Thirteen units may be connected in parallel on one AC branch, each pushing 1.9/1.8 A. There is no fan and no moving part: cooling is natural, audible noise stays under 25 dB, and the potted IP67 body of 1.85 kg tolerates humidity of 0 to 100% and altitudes to 2000 m. Deye states a 10-year warranty. We are an authorised Deye distributor and supply the SUN-M40G4-EU-Q0-I from our own stock, with technical support before and after the sale.
