PNI GreenHouse SP20KWT 20 kW Three-Phase On-Grid Solar Inverter with Anti-Backflow Protection

Product detailed description

The PNI GreenHouse SP20KWT is a three-phase on-grid solar inverter with a rated output of 20 kW. It converts the DC power from photovoltaic panels into AC power that can supply the loads in the house and feed surplus energy into the grid, or it can operate in self-consumption mode only.

The inverter has two MPPT trackers (22 A / 22 A), accepts up to 26 kW from the panels within a voltage range of 200 – 950 V, and its efficiency is above 98.2%. The output is a pure sine wave, which helps it synchronise with the grid. The IP65 rating allows outdoor installation.

You can follow production, grid injection and consumption in the SolarMAN mobile app. The package includes a Wi-Fi modem for communication and a three-phase meter with three current sensors (CT) that measure energy flow and are also used for anti-backflow protection.

Installation and connection

The inverter is wall-mounted with the supplied bracket or fixed to a vertical metal structure. It measures 635 × 225 × 480 mm and weighs 46.2 kg, so plan for a second person when lifting it. The operating temperature is −25 to +60 °C.

Important: system design, DC-side and three-phase grid connection and commissioning must be carried out by a qualified electrician experienced in PV systems. Connection to the grid must be arranged beforehand with your grid operator.
