The Sunway Series Three-phase string inverters are designed for residential and small commercial PV system applications, rating from 3kW to25kW. Al models have unibody housings with aluminum structure which is anodized, increasing durability and effectively prevents corrosionEquipped with external inductors. the unibody housing can ensure efhcient heat dissipation, which signifcantly improves the reliability ancextends the life of the inverters.
Communication implements are via the Wi-Fi module (can be changed to Ethernet / GPRS). Check the system status anytime and anywhere viaonline portal or APP System Architecture
