On-grid simply means solar-powered equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use. Off-grid systems are not affected by grid blackouts.

Yes, the JJN Solar Kit offers customization options. You can add or remove solar panels, batteries, and other components based on your power requirements. JJN Solar provides additional accessories to expand or modify your system as needed.

Yes, the kit is designed for DIY installation. However, it's important to have basic knowledge of electrical systems and safety protocols. Review the provided installation manuals, follow local electrical codes, and take necessary precautions when setting up the solar panels, inverter, and batteries. If unsure, consult with a professional electrician.

In order to determine what size of solar kit is appropriate to power an AC unit, you must first define the total load to be expected of the solar-powered system. Most manufacturers will publish a specification sheet of the AC unit online and will include a nameplate sticker on the AC body. Both can be used to determine the actual power rating of the AC. BTU is a common measuring unit for energy in AC and water heater products, but the important unit of measure is the energy rate, or simply power. Power will be listed in watts, and can be used to determine the total load resulting from running the intended AC unit. Multiply the power rating recorded in watts by the total number of hours of operation intended, to obtain the total watt-hours. Divide the total watt-hours by the peak sun hours in the location of installation, and multiply by a safety factor of 1.5-2, to obtain the total number of watts your panels should produce to power the air conditioner load. The total power load can be divided by the power output of one panel to obtain the number of panels needed.
