The solar‑powered self‑service drinking‑water vending machine is an on‑demand purified‑water retail terminal driven by photovoltaic power. It is designed for rural communities, remote scenic spots, construction sites, island camps and other locations with insufficient grid power supply.

High‑efficiency monocrystalline‑silicon solar panels are mounted on the machine top. Solar‑generated electricity is stored inside built‑in lithium batteries. The unit can run 24‑hours non‑stop with no external mains‑power supply, which realizes accessible fresh drinking water wherever sunshine reaches.

It is equipped with a multi‑stage RO reverse‑osmosis filtration system: PP cotton filter, activated‑carbon filter, RO membrane, post‑positioned activated‑carbon filter and ozone sterilization. Tap water, underground water and collected rainwater are all available as raw‑water sources. The treated water meets standards for direct drinking. After coin insertion or QR‑code payment, users simply press the button to fetch purified water from the bottom water outlet. Its straightforward operation suits people of all ages.

The floor‑standing dispenser adopts customizable blue‑and‑white water‑element themed appearance. It starts operation once connected to the water pipe and features flexible deployment. This machine serves as ideal supporting‑equipment for smart communities and eco‑friendly public‑water infrastructure.

1. Solar‑powered Operation With Zero Electricity Charges
Two high‑efficiency monocrystalline‑silicon solar panels are installed on the top. Solar‑generated electricity runs the whole machine and charges the built‑in lithium batteries in daytime. The equipment works completely independent of the municipal power grid. Sites with abundant sunshine achieve zero annual power expenses, and the dispenser runs reliably in remote off‑grid zones.

2. Multi‑stage RO Reverse‑osmosis Filtration for Direct‑drink Water
Equipped with a 10‑stage deep purification sequence: dual PP cotton filters, granular activated‑carbon filter, compressed activated‑carbon filter, RO reverse‑osmosis membrane, four post‑activated‑carbon filters and ozone sterilization. It thoroughly strips heavy metals, bacteria, viruses, sediment, residual chlorine and peculiar smells. The TDS value of finished water is kept ≤ 50 ppm, meeting national potable‑drinking‑water standards.

3. Wide Raw‑water Compatibility, Adaptable to Various Water Quality
It supports multiple water sources including municipal tap‑water, underground well‑water and rainwater collection systems. The built‑in pre‑filter and intelligent water‑quality sensor automatically adjust filtering strategies, guaranteeing safe and purified outlet‑water regardless of raw‑water conditions.

4. 24‑hour Unattended Self‑service Operation
Fully‑automatic workflow requires no on‑site attendant. Coin payment comes as standard, with optional modules for banknote acceptor, card payment and QR‑code checkout. The LED screen displays real‑time water TDS value, unit price and dispensed‑water volume. Users obtain purified water with one‑click operation.

5. Sealed UV‑sterilized Water‑fetching Chamber
A transparent dust‑proof access door matches the internal UV‑C sterilizing lamp. The water‑taking cabin maintains continuous disinfection to block contamination from dust and insects, safeguarding sanitary safety throughout water filtration and water‑taking procedures.

6. Energy‑storage Structure for Non‑stop Round‑the‑clock Operation
Large‑capacity built‑in lithium batteries store solar power on sunny days and supply power automatically at night or on cloudy‑rainy days. Low‑power‑consumption components enable 48‑72 hours of continuous operation without sunlight after a full battery charge.

7. Heavy‑duty Outdoor‑proof Construction
The IPX5 waterproof cabinet adopts anti‑rust surface coating and works under high‑temperature and low‑temperature outdoor conditions. Solar panels are encapsulated with tempered‑glass, resisting hail, sand and wind erosion for long‑term outdoor deployment.

8. Optional Intelligent IoT Remote‑management System
4G / Wi‑Fi IoT module enables remote monitoring for water TDS reading, filter‑cartridge service life, solar power generation, battery storage, sales logs and equipment fault alerts. Centralized management for multiple units greatly improves operational efficiency.

9. Fast Deployment, Ready‑to‑run After Water Connection
Every unit is fully assembled and calibrated before delivery. Operators only need to connect the water pipeline after on‑site delivery. No power‑cable laying or power‑capacity application is required, and the machine can start service the very same‑day of installation.

10. Eco‑friendly Design Supported by Government Policies
Driven by clean solar energy, the machine complies with carbon‑neutral goals and rural‑revitalization policy guidelines. It gains convenient official approval and policy preference for public‑water projects inside villages, communities and scenic spots.
