SMA Sunny Highpower PEAK3 150kW (SHP 150-21)150kW 1500V three-phase utility-scale PV inverter

Overview

The SHP 150-21 delivers 150kW at 600V AC from a 1500V PV array of up to 300kWp. One MPP tracker covers 880–1450V and accepts 180A through one or two inputs from external PV array junction boxes. Maximum efficiency is 99.1%, European efficiency 98.8%. It must be connected through a suitable medium-voltage transformer with a star-connected, grounded low-voltage winding. With SMA's project-specific DC Combiner Boxes the PV array can be oversized up to 200%.

How it works

Sunny Highpower PEAK3 is a transformerless PV inverter for large plants built on a decentralised design: PV strings are combined in external PV array junction boxes, which feed one or two DC inputs of the inverter's single MPP tracker at up to 180A. The SHP 100-21 works at 1100V DC and 400V AC; the 150, 172 and 180kW models use 1500V DC and 600, 660 or 690V AC. All models deliver a maximum of 151A on a 3-PE connection.

Key features

Maximum efficiency ranges from 98.8% on the SHP 100-21 to 99.2% on the SHP 172-21 and SHP 180-21, with European efficiency up to 98.9% and current distortion below 0.5%. Monitored type II surge arresters are installed on both AC and DC side, alongside ground fault monitoring, reverse polarity protection and an all-pole-sensitive residual current monitoring unit. OptiCool active cooling with speed-controlled fans allows operation from -25 to +60°C in an IP65 enclosure of 770×830×462mm and 99kg.

Installation and compatibility

The inverter is rack mounted on profile rails, indoors or outdoors, and is intended for industrial environments. Except for the SHP 100-21, which can feed directly into a low-voltage grid where local rules allow, operation requires a suitable medium-voltage transformer whose low-voltage side is star-connected with a grounded neutral. An external DC load-break switch, for example in the PV junction box, must be installed between PV array and inverter. DC cables connect with terminal lugs up to 300mm², AC with screw terminals up to 150mm².

Monitoring and grid codes

Two Ethernet ports carry SMA Modbus, SunSpec Modbus and Speedwire, and plants are normally configured through a System Manager such as SMA Data Manager. OptiTrac MPP tracking, Integrated Plant Control and Q on Demand 24/7 for night-time reactive power are included, and the inverter is off-grid capable and compatible with the SMA Fuel Save Controller. The datasheet lists IEC 62109-1/-2, VDE-AR-N 4110/4120, EN 50549, C10/11, CEI 0-16, G99/1, PO 12.3 and IEC 62116, and SMA publishes EN 50549 and VDE-AR-N 4110/4120 certificates. Warranty extends from 5 up to 25 years.
