Before our customer in Sierra Leone installed the 150kW solar system, he had to face uncertain power outages every day, ranging from 2 hours to 6 hours.
This was a huge threat to the food processing plant.
To ensure food safety, the production process should minimize the time food is exposed to the air. It should also complete the sealing and packaging through the machine as soon as possible.
However, this process requires a stable electricity supply.
Since it is unclear when power will be cut off, factory operations are very slow. This affects the quality and delivery time of the product, and the company suffers considerable losses as a result.
Since the customer installed our 150kW solar system, all problems have been solved.
They completed the installation work quickly according to our installation instructions. From the video feedback, we can see that their joy is beyond words.
Tips: The feedback node after customer use is 4 minutes and 7 seconds.
Is the 150kW solar system suitable for all factories?
Solar systems are not one-size-fits-all but require customized designs based on each factory’s actual conditions.
The selection and matching of every component, including solar panels, charge controllers, combiner boxes, battery energy storage, DC and AC inverters, brackets, wires, and installation tools, is crucial.
Their subtle changes may affect your factory’s normal operation.
For example, solar panels must be accurately calculated based on the factory’s power consumption to ensure sufficient power supply. In addition, the energy storage system design needs to fully consider the factory’s operating needs at night or on rainy days.
This is to avoid power shortages that lead to shutdowns.
PVMars will redesign and customize a solar energy storage system that suits your factory. You can download the load table and fill in the load of the machine you are using.

For the next 25-30 years, it is just about laying the foundation for a stable power supply for your factory.
What should you watch when using a 150kW solar system?
From the video, we can see that this is a solar energy storage solution designed with lithium batteries.
1-The lithium battery voltage needs to be consistent with the inverter DC voltage.
2-The steps for turning on and off the lithium battery are very critical. For specific related videos, click on the orange font to get them.
3-The solar charge controller should be designed to match the maximum charging voltage of the lithium battery to avoid overcharging.
4-The inverter discharge voltage cannot be higher than the discharge voltage of the lithium battery. This is to avoid over-discharge and reduce lithium battery service life.
PVMars will also provide detailed installation manuals and usage instructions for each customer.

Despite PVMars 150kW solar system's higher price, why do customers still choose us?
Even though there are cheaper solar systems on the local market, why do so many customers still choose PVMars?
There are multiple reasons behind this. First of all, there are probably three possible reasons:
1- Local suppliers also import from China but purchase larger quantities to get lower prices. However, because solar energy systems are industrial technology products.
For instance, solar panels made up of PERC technology were the most popular in 2021. Now they have been updated to TOPCon in 2024. Even perovskite solar panels have increased photovoltaic energy conversion efficiency from 18% to 26%.
2- If the lithium battery is not used for a long time, it needs to be fully charged every 3 months to activate the lithium iron phosphate electrons inside.
This is to maintain lithium battery capacity and life (12-15 years).
Since local suppliers purchase in large quantities, sales take several months. This may lead to an irreversible decline in lithium battery performance.
Therefore, if you want to purchase lithium batteries locally, you should pay attention to the time it takes for the lithium battery to be produced. You should avoid buying lithium batteries with a 2-3 year lifespan.
3- Most local suppliers provide high-frequency inverters. This type of inverter is small, lightweight, and easy to install. However, the biggest difference between it and low-frequency inverters is its load-carrying capacity.
No isolation transformer is designed for high-frequency inverters, so it is not suitable for air conditioners, refrigerators, and inductive loads with motors.
The output electric wave will be impure, causing machine malfunctions and light problems. So it is generally suitable for a variety of capacitor loads.
Therefore, the factory in Sierra Leone is more suitable for low-frequency inverters.
Finally, under PVMars’ professional guidance, they smoothly installed this 150kW solar power system.
PVMars’s solar system provides stable power but also determines your happy life in 25-30 years.
Regardless of whether you choose a PVMars solar system or not, we want to tell you about the risks of buying a solar system. I hope it helps you.
In summary, while there are cheap solar systems available on the local market, their quality and functionality are limited. Customers who want reliable power 24/7 will need to consider solar systems from China:
1) PVMars has rich industry experience and advanced technical advantages. During the manufacturing process, we perform strict quality checks on our solar products in order to ensure that they are reliable and stable.
For example, temperature test, an impact test, a quality control test, etc. Regarding how we tested, you can watch the lithium battery temperature test below for reference:
2) PVMars provides comprehensive pre-sales and after-sales services. A professional installation team will ensure the system is installed correctly and operates smoothly.
Providing after-sales technical support and maintenance allows customers to use their products without having to worry about anything.
We know that purchasing a solar system is not just a transaction, but an investment in a stable power supply for 25-30 years. Therefore, we always adhere to customer-centricity and create long-term value for customers.
Last but not least
While purchasing a solar system from China may involve certain transportation and installation costs, its superior quality and comprehensive service guarantee render it a more reliable and economical choice in the long run.
When making decisions, customers should consider multiple factors such as price, quality, and service. This will enable them to make an informed decision that truly meets their needs.
It is worth mentioning that PVMars Solar Energy Company is establishing a close long-term cooperative relationship with engineers in Sierra Leone and plans to establish a dedicated customer service and after-sales center.
We are committed to providing comprehensive, efficient, and free after-sales service to users who need solar energy storage systems to ensure your system operates stable and without worries.
PVMars means choosing a trustworthy partner; we will work together to create a greener future.
