2MW Containerized Energy Storage System for 4 upcoming towns


In 2019, we met Mr. Mxx (protecting user privacy) from a non-profit organization and successfully provided a 15kw three-phase off-grid solar energy storage system for their hospital.

The PVMARS solar system has operated well for the past 3 years.

Until 2022, Mr. Mxx has brought PVMARS another challenge: powering 4 newly industrialized towns in Botswana.

This is a government project, which is a cooperation between the government and non-profit organizations without public bidding, so the name and address of this project must be hidden.

If you have a similar project, contact us.

Because it is a newly industrialized town, there is no actual electricity consumption and load data support. For calculation and evaluation, it can only use the blueprint of Mr. Bxx, the local project leader, and other local data.

Mr. Bxx pointed out what industrialization entails – according to the needs of the national economy, more soda ash factories, textile fiber processing factories, cement factories, diamond factories, etc. Will be built.

While providing at least 5,000 labor forces for each industry. Should be installed at least one air conditioner, refrigerator, and cooking tool in each urban household. To meet the daily needs of people and let them enjoy a lifestyle of electricity freedom.

PVMARS is very happy for Botswana’s people. In this upcoming city, every household will enjoy solar energy’s independent, environmentally friendly, and inexhaustible renewable energy.


PVMARS solar energy experts conducted extensive research. In addition, we investigated the electricity consumption of commercial, industrial, and other towns in Botswana.

Also, the specific equipment inside the factories of the main industries was mentioned by Mr. Bxx.

Finally, we propose each town uses a 500kW container solar energy storage system.

Tailored specifically to meet the town’s energy needs. The system is mainly based on solar energy, which is both sustainable and cost-effective in the long run.

Design and implementation:

These four sets of 500kW (2MW) containerized energy storage systems are a solution to an efficient distributed photovoltaic energy matrix.

It ensures that the new town can obtain a stable and reliable power source, and the container design is very suitable for transportation and installation.

Which contains:

  • 3636 600W half-cell solar panels + ground support (designed for actual ground conditions)

  • PV COMBINER (an H10T waterproof PV combiner is installed for every 10 strings of solar panel components on average)

  • Power conversion system (PCS) —Contains bi-directional power control with multiple charging/discharging modes.

  • 1505kWh Lithium battery system ( each 51.2v280ah )

  • BMS+PMS (with data interface, can transmit data to the control cabinet, will be incorporated into SCADA, collect lithium battery data and display it on the computer)

  • HVAC(Heating, Ventilation, and Air Conditioning)

  • Dynamic environment monitoring system (which includes a fire suppression system).

  • Controller cabinet (with SCADA+EMS, computer remote monitoring, customized software)

  • Ancillary equipment: Junction boxes, cabling, lighting, sensors, breakers

  • Enclosure’s robust and rugged internal and external structure allows for regular re-deployment

Points 1-10 are the main components of this 2MW containerized photovoltaic energy storage system.

As for why these components are needed and what their functions are, please click on this article for relevant information.

The PVMARS team has now completed the production of a 2MW containerized energy storage system, which will soon be shipped to Botswana.

Each container will be equipped with technology to monitor energy usage.

This will ensure towns can manage energy consumption and optimize energy usage management.

5ft, 10ft, 20ft and 40ft types are available

Why apply for UN3536?

Lithium batteries are different from gel batteries. Lithium batteries are classified as Class 9 dangerous goods, which require an extremely safe environment to transport.

If the lithium battery is transported as an independent individual, the label is UN3481 or UN3480, as shown in the following picture:

UN3480 an independent lithium battery

If it is our container type, all lithium batteries will have been debugged, connected, and installed inside. You will need UN3536 safety standard certification.

In this container type, the user receives the product and uses it right away, without spending time on assembly and debugging, and without risking a wrong connection.

At PVMARS we are excited to embark on this upcoming project to provide sustainable electricity to newly industrialized towns in Botswana.

Our 2MW container energy storage system uses solar energy to provide efficient and clean electricity for towns and cities.

Not only is the solution cost-effective in the long run, but it is also environmentally responsible and sustainable, making it ideal for communities around the world.
