SMA Sunny Highpower PEAK3 100kW (SHP 100-21)100kW 1100V three-phase utility-scale PV inverter

Overview

The SHP 100-21 is the 100kW, 1100V member of Sunny Highpower PEAK3 and the only one with a 400V AC output, so SMA allows it to feed directly into a low-voltage grid where local rules permit. Its single MPP tracker works from 590 to 1000V and takes up to 180A from one or two external PV array junction boxes, for up to 200kWp of PV. Maximum efficiency is 98.8%, and monitored type II surge arresters protect both AC and DC sides.

• 100, 150, 172 and 180kW models

• Up to 99.2% max. efficiency
• Single MPPT, 180A input, 1 or 2 DC inputs
• Monitored type II AC/DC surge arresters
• Rack mounting, IP65, 99kg

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.
