GoodWe GW1500-XS-301.5kW single-phase string inverter, 1 MPPT

Overview

The GW1500-XS-30 delivers 1.5kW single-phase from one PV string. Its MPP tracker works from 40 to 450V with a 50V start-up voltage and accepts up to 16A, enough for current large-format modules. Maximum efficiency is 97.2% and European efficiency 96.0%. The housing is 306×218×119mm, fanless and quieter than 20dB, so it can be mounted inside a house. Type III surge protection is standard and AFCI is an option. GoodWe suggests a 16A AC switch for this model.

• 4.6kg and 306×218×119mm
• Fanless, below 20dB, IP66
• Plug-and-play AC connector
• Wi-Fi, LAN, Bluetooth or 4G options

How it works

Each XS G3 inverter has a single MPP tracker for one string, with a 600V maximum input, a 50V start-up voltage and 16A input current, enough for current high-power modules. The tracking range is 40–450V on models up to 2kW and 40–550V on the 2.5kW and 3kW models. The output is single-phase 220, 230 or 240V, and the rated power equals the maximum output power.

Key features

The housing weighs 4.6kg, has no fan and stays below 20dB, so it can be fitted inside the house or on an outside wall. Protection covers string current, insulation and residual current monitoring, reverse polarity and an integrated DC switch. Type III surge protection is standard on DC and AC, with Type II and AFCI available as options. With a meter the inverter can limit export and record household consumption around the clock.

Installation and compatibility

Mount the inverter vertically or tilted back by up to 15°, never horizontally or upside down, at an altitude below 4000m. GoodWe recommends a 16A AC switch for the 0.7–1.5kW models and 25A for the 2–3kW models, and, where an external RCD is required, a Type A device of at least 300mA. The AC side uses a plug-and-play connector and the DC side MC4 connectors for 4–6mm² cable.

Export limitation uses a GM1000 or GMK110 single-phase meter or a CT; in three-phase houses a GM3000 or GMK330 meter can measure all phases. A DRED/RCR port is available for ripple control receivers. CEI 0-21, VDE-AR-N 4105, EN 50549-1, EN 50549-10, NC RfG and G98 certificates list all XS G3 models from GW700-XS-30 to GW3300-XS-30.

Monitoring and settings

Parameters can be set on the LCD or with the SEMS+ app over Bluetooth or Wi-Fi. Plant data reach the SEMS+ portal through Wi-Fi or LAN, or through an optional 4G module. RS485 with Modbus RTU and Modbus TCP is available for smart home systems and energy managers. Remote shutdown and the DRED/RCR functions are enabled in the app after wiring.
