01 · About MAXGREEN
Who we are and who we supply.
A factory-direct partner built for business customers, with OEM and ODM options and tailored solutions.
Who is MAXGREEN, and do you make the chargers yourselves?
Yes. MAXGREEN (Foshan Maxgreen New Energy Technology Ltd.) designs and builds EV chargers in its own factory in Foshan, China, and has done so since 2016. The factory runs four production lines under ISO 9001 quality management, backed by a technical team of more than 30 people and an R&D centre in Shenzhen.
Who do you work with?
MAXGREEN is built to serve businesses. Our customers include distributors, installers, charge point operators, property and fleet owners, and brands that want their own label. We offer OEM and ODM options and work with you on a solution that fits your project, your market and your volumes.
Which markets do you supply?
We supply customers worldwide. Models and connectors are matched to each market, for example 7–22 kW or 32–80 A wallboxes with Type 2, Type 1 or GB/T connectors. Tell us your destination country when you ask for a quote.
What should I send to get an accurate quote?
Send us four things: your target market, your power supply (single- or three-phase and voltage), the connector type you need and the quantity. Tell us as well if you need OEM branding or an OCPP connection to your platform. We will recommend a model and reply as soon as possible.
02 · Ordering & OEM
Order size, OEM and lead time.
Small batches, your own branding and clear delivery times.
What is the MOQ for OEM chargers?
There is no fixed minimum order quantity. We accept small-batch orders and can ship a single unit as a sample. The exact terms for OEM customization depend on the product, so tell us the model and quantity and we will confirm.
What can be customized under OEM?
Under OEM you can add your logo (screen printing or laser engraving), your own packaging, manuals in your language and a custom housing colour.
What does ODM include?
ODM covers deeper changes: a localized screen and app interface, OCPP feature extensions and hardware integration, developed to your specification for larger projects.
What is the lead time for stock and custom orders?
Stock models typically ship within 3 working days. Custom and OEM orders typically take 25–30 working days, because they are scheduled into production. The exact timing depends on the model and quantity.
Do you offer samples, small batches or mixed-model orders?
Yes. We support sample units, small batches and mixed-model orders. The details depend on the product, so send us the models and quantities you have in mind.
Which languages are manuals and packaging available in?
Manuals and packaging can be produced in the language you need. Tell us your target market when you order and we will prepare them for it.
03 · Certification
Certificates and standards.
Documents are supplied per model and per market, before you order.
Which certifications do your chargers hold?
Certification depends on the model and the target market. For example, the MG-A09 is ETL Listed and FCC certified. Tell us the model and your destination country and we will confirm the certificates that apply.
Can I get certificates and declarations of conformity before ordering?
Yes. We can send the certificates and declarations of conformity for your model before you order, normally within one working day. Ask through the form below or on WhatsApp.
Which standards are the chargers designed to?
Our AC chargers are designed to IEC 61851 and SAE J1772, and our Mode 2 portable chargers follow IEC 62752.
Which compliance documents can I get for my country?
Requirements differ by country, so we match the model and its documents to your destination. Models supplied to Europe are supported with CE and UKCA conformity documents. For any other country, tell us where the chargers will be installed and we will confirm what applies.
04 · Products
Choosing the right charger.
Three product families, the main connector standards, and how to match them to your market.
What types of chargers do you offer?
We offer three families: Mode 2 portable chargers (3.5–22 kW, single- and three-phase), smart AC wallboxes (7–22 kW, or 32–80 A versions) and DC fast chargers up to 240 kW.
Which connector standards do you support by market?
We support the main standards: Type 1, Type 2, GB/T and Tesla/NACS for AC, and CCS1, CCS2 and GB/T for DC. Tell us your market and we will match the connector.
Which type fits a distributor's range: wallbox, portable or DC?
It depends on your customers. Wallboxes suit fixed sites such as car parks, hotels and fleet depots. Portable chargers are plug-in units that need no installation, which suits resellers and rental fleets. DC chargers suit sites that need fast turnaround. The cards below show the three families.
Single-phase or three-phase, and what power do I need?
Power depends on the supply at the site. Our wallboxes range from 7 to 22 kW, or from 32 to 80 A depending on the version, and our portable chargers cover 3.5 to 22 kW in single- and three-phase versions. Send us your supply details and we will recommend a model.
Do your chargers work with all EV brands?
A charger works with any vehicle that uses the same connector and charging standard, so compatibility follows the connector rather than the car brand. For a specific vehicle, send us the model and we will check it.
For fixed sites such as car parks, hotels and fleet depots.
Plug-in units that need no installation, from 3.5 to 22 kW.
For sites that need fast turnaround, up to 240 kW.

05 · OCPP & Software
OCPP, app and platform support.
Connect to your platform, test it first, and keep it up to date.
Do your chargers support OCPP?
Yes. Our networked wallboxes support OCPP 1.6J, so they can connect to OCPP-compliant charging platforms.
Can they be upgraded to OCPP 2.0.1?
Yes. The MG-A09 and MG-L01 can be upgraded to OCPP 2.0.1 over the air, without replacing the hardware.
Can you test with our platform before rollout?
Yes. We can send you a sample unit to test, or our development team can run the connection test with your platform for you.
What is the difference between the App version and the OCPP version?
Each charger ships with one firmware version. The App version is controlled through the ChargeMAX app, and the OCPP version connects to a charging platform. To change version later, contact us for the firmware package, as the switch is not available to end users.
What is dynamic load balancing and which models include it?
Dynamic load balancing shares the available power between several chargers so the site does not overload its supply. It is an optional module rather than a standard feature, and availability depends on the model, so check the product page or ask us.
How do users authenticate?
Chargers can be started with an RFID card or through the app. The MG-A09 comes with two RFID cards in the box, and ISO 15118 is available as an option.
06 · Outdoor & Safety
Built for outdoor sites.
Protection ratings, temperature range and built-in safeguards.
Are the chargers suitable for outdoor use?
Yes. Our outdoor-rated models carry IP65 protection; the MG-A09 is rated NEMA 3R (IP65) with IK10 impact resistance. Protection ratings differ by model, so check the table below or the product page.
What operating temperature range do they support?
Our IP65 options are rated for −30°C to +50°C. The range for each model is listed on its product page.
What protections are built in?
Protections depend on the model. For example, the MG-A09 has 10 protection circuits and the MG-A08 has 8 protection layers. See the product page for the full list for your model.

Specifications vary by model and market. The product page and datasheet always prevail. Ask us for the datasheet of any model.
07 · Installation
Installation and documents.
What your installer needs, and where to get it.
Who should install the charger?
A qualified electrician should install it in line with local wiring regulations. A manual is supplied with every unit, and wiring diagrams are available on request.
Wall-mount or pedestal installation?
Both. A wallbox can be fixed to a wall, or mounted on a MAXGREEN pedestal where there is no suitable wall, which also avoids drilling into a wall.
What breaker, RCD and cable do I need, and can cable length be customized?
Breaker, RCD and cable sizes depend on the model and on local regulations, and we give them in the manual and on request for your project. The charging cable and the input cable can both be made to the length you need.
Where do I get manuals, wiring diagrams and install videos?
A manual is packed with every charger. Install videos and wiring diagrams are available on request, through the form below or on WhatsApp.
08 · Warranty & After-sales
Warranty and after-sales support.
Clear terms, remote diagnosis first and a fast response on RMA requests.
How long is the warranty?
It depends on the product. For example, the MG-A09 has a 3-year warranty. Tell us the model and we will confirm the warranty for it.
What does the warranty cover?
The warranty covers manufacturing defects and material faults that are not caused by misuse or damage.
How does after-sales support work?
We start with remote diagnosis. If the fault is in the hardware, we replace parts or repair the unit. We respond to RMA requests within 2 working days.
How are firmware updates delivered?
Firmware updates are delivered remotely, so no site visit is needed. Firmware packages for the App and OCPP versions are on our after-sales page.
Do you offer extended warranty or framework agreements?
Yes. We can discuss extended warranty and framework agreements for larger projects. Tell us the volume and term you have in mind.
