FAQ

1. Does this kit include everything I need to install it?

Yes, the kit includes all components needed for installation: solar panels, battery, inverter, MPPT controller and accessories.

2. Can this kit run a refrigerator? For how long?

Yes, this kit can power a refrigerator. Depending on the refrigerator’s power usage, it can run for approximately 12 hours on a full charge from the 100Ah battery. A standard 80W fridge can be powered for about 12 hours. This duration will vary based on the energy consumption of the specific model you are using.

3. Can it power a microwave, coffee maker, or air conditioner?

Yes, this kit can power devices like a microwave, coffee maker, or air conditioner, as long as their power consumption is within the 2000W inverter capacity. Ensure the total wattage of the appliance does not exceed 2000W.

4. Can I add another 100Ah battery later?

Yes, you can add another 100Ah battery to expand storage capacity. However, batteries cannot be connected in series because the inverter operates at 12V, so the batteries must be connected in parallel.

5. Can I add more solar panels? What is the maximum input of the MPPT controller?

Yes, you can add more solar panels. The MPPT charge controller has a maximum input of 600W for a 12V system, so you can expand up to 600W (6 x 100W panels) for optimal performance. Just ensure you maintain compatibility with the controller’s input limits.

6. Is the inverter pure sine wave?

Yes, the inverter in this kit is a pure sine wave inverter, providing clean and stable power suitable for sensitive electronics.

7. Can I install the panels on an RV roof?

Yes, the panels can be installed on an RV roof. They come with mounting brackets that make it easy to secure the panels to a flat surface, like an RV roof, using standard mounting hardware.

8. Are the solar panels waterproof?

Yes, the solar panels are IP65 rated, meaning they are waterproof and suitable for outdoor use in all weather conditions.
