SMA

Three-phase string inverters for commercial rooftops and carports are the part of the SMA program that contractors in the Gulf ask for most. SMA has built solar inverters and energy systems in Niestetal, Germany since 1981.

Seven Star LLC, an independent supplier in Muscat, lists the Sunny Tripower CORE1 STP 50-41 and sources SMA solar inverters and their accessories for PV projects in Oman on request.

SMA Sunny Tripower CORE1 STP 50-41 in brief

The STP 50-41 is a 50 kW transformerless three-phase inverter. SMA’s datasheet gives it six independent MPP trackers with two string inputs each, a maximum DC input voltage of 1000 V, an IP65 enclosure and an operating temperature range of -25 to +60 °C. The CORE1 is a free-standing unit, so it is set on the roof or ground without a wall or rack behind it.

Ordering SMA inverters: what we need

Send the full type designation as printed on the nameplate (STP 50-41, not only “CORE1”), the grid voltage and frequency, the utility or grid-code requirement that applies in your GCC country, and any surge protection or communication options. For a replacement unit add the serial number or a nameplate photo. We check the code against SMA documentation and provide the manufacturer’s datasheet and certificates on request.
