Three-phase solar inverter PNI GreenHouse SP20KWT 20 kW on-grid with anti-backflow protection
Code: PNI-SP20KWT-SProduct detailed description
PNI GreenHouse SP20KWT is a three-phase on-grid solar inverter with a rated power of 20 kW. It converts direct current from photovoltaic panels into alternating current, which can power household appliances and feed excess energy into the grid, or it can operate in self-consumption mode only.
The inverter has two MPPT controllers (22 A / 22 A), accepts up to 26 kW from panels in a voltage range of 200 – 950 V, and has an efficiency of more than 98.2%. The output is a pure sine wave, which ensures good synchronization with the grid. The IP65 protection rating allows for outdoor installation.
You can monitor generation, grid feed-in, and consumption using the SolarMAN mobile app. The package includes a Wi-Fi modem for communication and a three-phase meter and three current transformers (CT) for measuring energy flow, which also serve as protection against reverse feed into the grid.
Installation and Connection
The inverter is mounted on a wall using the provided bracket or on a vertical metal structure. The dimensions are 635 × 225 × 480 mm and the weight is 46.2 kg, so you should expect to have assistance when lifting it. The operating temperature range is −25 to +60 °C.
Important: system design, DC-side connection, and commissioning to the three-phase grid must be carried out by a qualified electrician with FV system testing experience. Connection to the grid must be arranged in advance with the electricity distributor.
Package Contents
Inverter, wall bracket, reverse flow meter, 3 current sensors, Wi-Fi modem, MC4 connectors, mounting hardware, and user manual.
Frequently Asked Questions
Can grid feed-in be limited?
Yes, the inverter has a feed-in limitation function and can also operate in self-consumption mode only, which is supported by the meter and CT sensors.
Is the Wi-Fi module included in the package?
Yes, the Wi-Fi modem is part of the delivery.
Can it be installed outdoors?
Yes, the IP65 protection rating and temperature range of −25 to +60 °C allow for outdoor use.
