GoodWe | XS G3 Solar Inverter 1.5kW Single Phase 1 MPPT | IP66 Non-Isolated
The GoodWe GW1500-XS-30 is a 1.5kW single phase grid-tied solar inverter from the XS G3 series, built around a single MPP tracker taking one string. The GW1500-XS-30 delivers 1500W nominal output at 220, 230 or 240V AC, with a maximum efficiency of 97.2% and a European efficiency of 96.0%. It carries an IP66 ingress rating and cools by natural convection, so there is no fan to fail or to make noise. The unit weighs 4.6kg and measures 306mm wide by 218mm high by 119mm deep.
A 1.5kW inverter answers a specific constraint rather than a general preference. Some connections carry a network export limitation that renders a larger unit pointless, and some roofs accommodate only four or five modules once obstructions are deducted. Specifying additional inverter capacity into either situation consumes capital without contributing generation. The GW1500-XS-30 covers that bracket with 1500W nominal output, 200% DC input oversizing and a 40 to 450V MPPT window.
Installers pricing small systems watch the fixed costs, because the inverter, the isolation equipment and the labour do not scale down alongside the array. The GW1500-XS-30 weighs 4.6kg in an A4-sized body, which positions it on the bracket in a single lift without a second operator. Its plug and play AC connector and MC4 DC connectors reduce termination time on an installation where the margin is already thin. Commissioning and monitoring both run through the onboard LCD and the application over WLAN.
Features
- 1.5kW nominal output — the GW1500-XS-30 delivers 1500W nominal active power and 1500VA apparent power at a maximum output current of 6.9A.
- 200% DC oversizing — the array can be sized to twice the inverter rating, which lifts generation through mornings, afternoons and overcast conditions.
- 97.2% maximum efficiency — the GW1500-XS-30 peaks at 97.2% conversion efficiency, with a European weighted efficiency of 96.0% across the load range.
- Single MPP tracker — one tracker taking one string, rated to 16A maximum input current and 25A maximum short circuit current.
- 40 to 450V MPPT window — the tracking range holds the array at its maximum power point as irradiance and cell temperature change through the day.
- IP66 ingress rating — sealed to IP66, so the GW1500-XS-30 mounts indoors or outdoors in an exposed position.
- Fanless natural convection — cooling is passive with no fan, keeping noise emission below 20dB and removing the most common moving-part failure.
- Integrated protection set — PV insulation resistance detection, residual current monitoring, PV reverse polarity protection, anti-islanding and a DC switch are all built in.
- Type III surge protection — Type III surge protection on both the DC and AC sides, with Type II available as an option on either side.
- A4 footprint at 4.6kg — 306mm wide, 218mm high and 119mm deep, light enough for one installer to mount without a second pair of hands.
- Single string limit — the GW1500-XS-30 has one MPPT accepting one string only, so arrays split across two orientations cannot be tracked separately.
Where to use
- Apartments and small dwellings — four to six panel systems where roof area or strata approval keeps the array to a small footprint.
- Export-limited connections — the GW1500-XS-30 suits sites where the network operator caps export and larger inverter capacity would return nothing extra.
- Granny flats and secondary dwellings — self-contained dwellings on a modest single phase supply with a small dedicated array.
- Sheds, studios and outbuildings — the GW1500-XS-30 suits standalone grid-connected structures where the roof carries a single string.
- Inverter replacements — swapping a failed or out-of-warranty unit on an existing small array without re-engineering the string.
- Monitored installations — systems where the owner or installer wants remote performance data through WiFi, LAN or RS485 into a monitoring platform.
The GW1500-XS-30 is a grid-tied inverter and does not provide backup or off-grid supply, so it stops exporting when the grid drops out. It has one MPPT taking a single string, which rules out arrays split across two roof faces with different orientation or shading. Installation and grid connection are restricted to a licensed electrician holding the relevant solar accreditation.
