SMA Sunny Highpower PEAK3 SHP 150-21 150 kW Solar Inverter
Description
The SMA Sunny Highpower PEAK3 SHP 150-21 is a transformerless three-phase central-string inverter rated 150 kW at a 600 V AC grid connection, built for utility-scale and large industrial PV plants that use 1500 V DC strings. It belongs to the four-model SHP-21 family and is the 600 V variant, which suits plants that connect through a medium-voltage transformer station at this nominal voltage.
High power density for decentralised 1500 V plants
SMA describes the Sunny Highpower PEAK3 as the core of its solution for decentralised PV power plants with 1500 V DC system voltage. A single MPP tracker accepts up to 180 A of usable input current, with one or two optional inputs for external PV array junction boxes. A DC/AC ratio of up to 200 % is possible, and the datasheet states there is no derating up to 50 °C. At about 99 kg the unit is rack mounted and sealed to IP65, with active speed-controlled OptiCool cooling.
The inverter is off-grid capable and compatible with the SMA Fuel Save Controller, which matters for hybrid sites that combine solar with diesel generation. OptiTrac tracking, Integrated Plant Control and Q on Demand 24/7 reactive-power capability are standard, and the SMA Data Manager provides central commissioning and control of the plant.

Selecting and ordering
Match the AC nominal voltage of the model to the transformer station first, then size the DC side: with a 1500 V array the 880 V to 1450 V MPP window and the 180 A input limit set the string count per inverter. Confirm the grid code that the project requires, because the datasheet lists the approvals as pending and the certificate set can differ by region and date. The manufacturer states a standard warranty of 5 years with extensions optional. For a smaller commercial string inverter see the SMA Sunny Tripower X 25, or browse all solar power products.
How the SMA SHP 150-21 works
The inverter takes DC power from the solar strings and tracks the point of maximum power. It converts the DC power into three-phase AC at the grid voltage. It follows the grid frequency and voltage and can supply reactive power on demand. Monitoring circuits watch the grid and the DC side.

About brand
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.
