3. Can I use a third party solar panel?

Most of the solar panels on the market are compatible, but you need to check whether the specifications and plug are matched (Within 150V, and the connection port is Anderson), you also can feel free to contact us via email before connecting them.

However, we do suggest customers connect the OUPES solar panel with the OUPES solar generator, as there is already a solution provided in the generator and also the third-party solar panel.

Different companies' solutions may conflict, causing charging not to be done as efficiently as desired although they are universal.

4. Can I use a third party expanded battery?

No, the MEGA 2 can't be expanded with a third party battery. Please choose the B2 expanded battery with it.

5. What type of battery does OUPES use?

LiFePO4 - The Battery is estimated to have over 80% of your original capacity after 3500 cycles, with a gradual reduction after that. (Note: this doesn't mean the battery only has a 3500 cycle life span. It means that up until 3500 cycles, the unit can perform at its best. However, due to battery degradation there will be a gradual decline in performance after 3500 cycles.) 

It has a 6 times longer lifespan than ordinary lithium batteries. LiFePO4 battery is much safer, more stable and more eco-friendly with no heavy metal elements that are harmful to people.

6. How do I know if the MEGA 2 can power my device?

The OUPES MEGA 2 can run any device that requires less than 120V and 2500W. You can calculate the charge time using the following formula: 2048Wh* 0.85 / operating power of your device.

7. Does it support pass-through charging?


8. Does the OUPES MEGA 2 package come with all the charging cables?

Yes, the OUPES MEGA 2 package will come with all the charging cables, you don't need to purchase any extra cables.

10. Is the solar panel waterproof? Can I use an extension cable?

We have waterproof treatment for solar panels, but we do not recommend you use them in the rain. Portable solar panels cannot be fully waterproofed like hard solar panels. Long-term exposure to rain may reduce cell efficiency. The length of the solar charging cable is 16ft long. We also provide the extensions on the website. Please note that the charging efficiency may be reduced due to the charging cable being prolonged. It might require more time to finish charging with extension cables.
