What are your questions?

During the entire sales process, we conduct pre-sales consultation to tailor solutions according to specific needs by provide detailed product specifications and technical documentation to help our partners understand the features and capabilities. Our most unique offerings are provision of system designs and customization options, arranging for safe shipping and delivery, different branding options, warranty extension, among others.

Yes, we also offer Original Design Manufacturer and Original Equipment Manufacturer services, also known as ODM and OEM respectively. Omnivoltaic is the only solar manufacturing company which can offer the services from design and scheming to manufacturing, as we have mastered the most advanced technology in the energy storage systems space. We offer these services on minimum order quantity basis.

Most of our Portable Solar Power Station products have acquired the CE, FCC, UL, and PSE certification, all which is able to satisfy most country’s importing requirements.

The power of the inverter is expressed in kW while the storage capacity of the battery is expressed in kWh.

Retaining some battery capacity is very essential in initiating the chemical reaction during charging. This means that a battery capacity must never be consumed to 100%. The depth to which a battery can be discharged depends on the chemistry in the battery. Most systems automatically shut off after attaining a battery capacity range of 5-15%.

For Omnivoltaic, all our battery systems are fitted with a Battery Management System, also BMS, which among other benefits, assists in retention by limiting the complete exhaustion of the battery capacity. This is very important for our distributors because it ensures the battery quality and shelf life is maintained.

All Omnivoltaic products are fitted with Lithium Iron Phosphate (LFP) batteries because they have a higher energy density, lighter weight, higher charge and discharge efficiency, longer life span, and lower maintenance requirements compared to Lead-Acid Batteries. The chemical composition of LFP cells virtually eliminates the risk of overheating and thermal runaway, making them safe and non-flammable even in extreme conditions.

Although Lead-Acid Batteries are relatively cheaper, they can only be discharged halfway, requiring a larger battery capacity. In addition, they are slowly being replaced by lithium-ion technology, which has undergone a gigantic evolution in terms of capacity and price, making the LCC (Life Cycle Cost) much more favourable. 

Please carefully review the product manual; as long as non-inductive loads do not exceed our rated load, they can be used.

If unused, power banks and power stations are typically capable of holding a full charge for 12-14 months. However, we highly recommend using and charging the battery every 3-4 months for a healthy lifespan and storing your power bank or power station plugged into the wall or solar panel if possible.

"Battery lifecycles" refers to the number of charge and discharge cycles that a rechargeable battery can undergo before its capacity and performance significantly degrades. Each time a battery is fully charged then fully discharges is described as one battery cycle. The total number of cycles a battery can endure is an important factor in determining its overall lifespan and long-term usability.

You'll want to consider a few key factors:

• Voltage and Compatibility : Ensure that the solar panel voltage output matches the input requirements of your portable power station. They should be compatible in terms of voltage and connector types.
• Solar Panel Capacity : The wattage or capacity of the solar panel should be suitable for charging the power station efficiently. Check the power station's input wattage limits and choose a solar panel within that range.
• Charge Controller : Some portable power stations come with built-in charge controllers, while others require an external one. Make sure your setup includes the necessary charge controller to regulate the solar panel's output and prevent overcharging.
•   Cable Length and Connectors
•   Sunlight Exposure
• Panel Type : Decide between monocrystalline, polycrystalline, or thin-film solar panels based on your specific needs, such as efficiency, portability, and budget.
• Portable or Fixed : Determine if you need a portable solar panel that can be easily moved or a fixed installation for more permanent use.

Omnivoltaic is always keen when considering these factors, to enable end-users effectively match a portable power station with a solar panel for reliable and efficient off-grid power generation. For any queries on this, feel free to contact us.

Omnivoltaic has established a long-term relationship with professional and highly experienced forwarders across different countries. Upon request, we have been able to oversee both sea and air shipments on behalf of our partners.

We are very familiar and compliant with customs and shipping regulations and depending on the nature of products and size of order, sometimes we are able to assist with clearance procedures in the importing countries.

Our Solar Energy Storage Systems range from 1kWh to 20kWh.The maximum battery capacity allowed to be shipped normally by air is 100Wh. For any battery above 100Wh, under the discretion of the air freighter, requires the provision of the battery certificates such as Material Safety Data Sheet, commonly known as MSDS, which we can provide for all our systems.

For general minor problems, our company will issue maintenance instructions and express spare parts. Customers can repair and replace spare parts by themselves according to the instructions. If it cannot be repaired within the warranty period, our company will provide a new product replacement.

OVES Warranty Policy is provided by OVES, and defects can be covered in the form of workmanship and materials.
