The photovoltaic power storage and charging all-in-one machine is a comprehensive device that integrates photovoltaic power generation, energy storage system and charging functions. It is introduced in detail as follows:

I. Components of the photovoltaic power storage and charging all-in-one machine

Photovoltaic power generation system: including photovoltaic components (such as solar panels), brackets, inverters, etc., used to convert light energy into electrical energy.

Energy storage system: usually composed of energy storage batteries (such as lithium-ion batteries), used to store excess electricity generated by photovoltaic power generation systems and release it when needed.

Charging equipment: Provide charging services for electric vehicles or other devices.

II. Working principle of photovoltaic power storage and charging all-in-one machine

The photovoltaic storage and charging machine coordinates photovoltaic power generation, energy storage and charging processes through an intelligent management system. The specific working principle is as follows:

When the photovoltaic component receives solar energy, it converts it into electrical energy.

The electrical energy is converted into alternating current through an inverter for use by household appliances or charging the energy storage system.

The energy storage system stores electrical energy when there is sufficient electrical energy, and provides charging services for electric vehicles or other devices when there is insufficient electrical energy or when needed.

Parking lots: Especially large commercial complexes or public parking lots, photovoltaic carports can be installed to integrate photovoltaic power generation, energy storage and electric vehicle charging.

Industrial parks: Use roofs and other idle spaces to install photovoltaic panels to achieve energy self-sufficiency, while providing charging services for electric vehicles in the park.

Office areas: Install photovoltaic panels and energy storage facilities on roofs or parking lots to provide charging services for employees' electric vehicles, and use excess electricity to power office areas or sell to the grid.

Home and commercial areas: Provide users with self-sufficient clean energy and reduce dependence on the grid.

Q1: Are you trading company or manufacturer?

A: We are a professional electric car charger manufacturer and source factory.

Q2: what is the lead time?

A: Usually, 15-20 working days to produce.

Q3: Can we ask you to print our logo into chargers? Can the color of the plug and wire be customized according to our requirements?

A: Yes. We support OEM/ODM production.

Q4: How about your product quality? What should I do if something goes wrong?

A: First of all, we sell our products for many years, and we have a professional engineering team in this field. Moreover, our products have been strictly inspected and repeatedly tested before leaving the factory, and the good and good rate of the varieties has reached 99.98%. Finally, we have service providers in some areas, please contact us for more information

Q5: What is your quality control system?

A: Complete all incoming material inspection, process inspection, and final inspection; 30 test procedures will be done before the goods leave the factory, and charging test videos will be sent; products have CE, ROHS, FCC, UL, KC certification.

Q6: Can I install the EV charger by myself?

A: Yes, but we suggest the user contact a professional electrician for installation to avoid potential safety hazards.

Q7：Why my charging power is lower than the specification?e?

A: Because during the charging session, a few factors will influence the output. Here is some potential reason:

①The BMS(Battery management system) of the car controls the charging session.

②The Max allowed current was set and limited through your APP.

Q8: How much time is required to fully charge my car using this charger?

A: The charging speed is determined by three factors working in conjunction: the On Board Charging (OBC) System, the maximum current allowed by the charging cable, and the EVSE. As an illustration, if the EV's maximum allowed power is 30KW and the battery capacity is 60KWh, it would take approximately 2 hours to charge the battery fully.

Q9: What is dynamic load balancing and why do I need that?

A: Dynamic load balancing is a technique that distributes the electrical load across multiple charging stations based on real-time demand. This helps prevent the electrical grid's overload and ensures that each charging station receives appropriate power.

Dynamic load balancing technology can help distribute the available power among multiple EV chargers in real-time, optimizing available power and reducing the risk of overloading the grid. This can help prevent power outages and reduce the need for costly grid upgrades.

Additionally, dynamic load Balancing can help reduce charging times and improve the overall charging experience for EV drivers, making it a valuable feature for both residential and commercial charging applications.
