“GreenTech solar car charger” does not identify a confirmed product model. Available listings associate Sichuan Greentech YT New Energy Co., Ltd. with EV charging equipment, including one marketplace listing for a 7 kW solar EV charging station, but the title alone does not show whether you mean that unit, a different EV charger, or a 12 V solar battery maintainer. The listing details below are seller claims, not independently verified test results.
What does “GreenTech solar car charger” mean?
The phrase can describe two different kinds of equipment:
- A solar-compatible EV charging station: equipment for charging a plug-in road vehicle, typically connected to a home electrical supply. “Solar” may refer to using electricity from a solar installation; it does not, by itself, establish that solar panels are built into the charger.
- A 12 V solar battery maintainer: a small device intended to maintain a conventional vehicle battery. It is not an EV charging station and cannot charge an electric car’s high-voltage traction battery.
The supplier catalog surfaced for Sichuan Greentech YT New Energy Co., Ltd. lists EV charging equipment, including Type 1 and Type 2 products, but does not resolve which product the title intends. The supplier describes Type 2 equipment for European and UK markets and Type 1 equipment for North and South American markets; that catalog-level description is not a compatibility guarantee for a specific charger.

What does the surfaced 7 kW listing claim?
A Made-in-China marketplace result describes a “7kw Solar Electric Car Charger Home Use Charging Point Solar EV Car Charging Solutions” attributed to Sichuan Greentech YT New Energy Co., Ltd. The surfaced result does not name an exact model. Its specifications should therefore be treated as claims for that listing, not as specifications for every GreenTech charger.

These values are not independent measurements, and the listing does not explain how the alternative current and voltage figures relate to particular configurations. The marketplace result is available at Made-in-China’s solar-car listings.
What to confirm before deciding whether it fits?
Vehicle and connector
First establish whether you need to charge a road EV or maintain a 12 V battery. For an EV, confirm the connector on the exact unit and that it matches your vehicle or a suitable, approved adapter. Do not infer a charger’s connector from the supplier’s general catalog or from its regional Type 1 and Type 2 descriptions.

Electrical supply and output
Ask for the exact model’s rated power, current, voltage, and phase configuration, then check those against your home supply and the vehicle’s charging limits. The 7 kW listing’s figures do not establish that every configuration is available in your country or suitable for your installation.

How solar power is involved
Ask whether the proposed setup uses direct photovoltaic output, a grid-connected solar system, or solar paired with battery storage, and whether the charger can manage surplus solar generation. The word “solar” in a listing does not establish that panels, an inverter, storage, or solar-aware charging controls are included.

Installation, protection, and documentation
Before purchase, obtain the installation manual and confirm the required circuit, protective devices, cable arrangement, and local electrical-code requirements with a qualified installer. Check the exact unit’s weather-protection rating, warranty, safety certifications, and cable length in its documentation; the listing’s IP54 and 5 m claims alone do not establish compliance or suitability for a particular location.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is this a review of a verified GreenTech model?
No. The available information connects the supplier with EV charging products and surfaces one 7 kW marketplace listing, but it does not establish a uniquely identifiable model, independently tested performance, verified savings, or compatibility with a particular vehicle or home installation. It also does not establish Amazon availability. Without the exact model and configuration, a product verdict would be premature.
