Quick Answer
Connecting series panels from different manufacturers can be done, but it's essential to ensure the panels are compatible in terms of voltage, current, and wire size, and that you follow proper safety guidelines and manufacturer recommendations.
Compatibility Requirements
When connecting series panels from different manufacturers, you’ll need to verify that the panels’ voltage, current, and wire size are compatible. This typically involves checking the panel specifications and ensuring that the maximum system voltage and current ratings are not exceeded. For example, if you’re connecting two 48V panels in series, the total voltage of the system should not exceed 96V.
Series Panel Wiring Techniques
To connect series panels safely, it’s recommended to use a single string of panels with the same number of panels in series. If you’re connecting multiple strings of panels in parallel, ensure that each string has the same number of panels and that the total current rating of each string is balanced. Use a high-quality DC combiner box to connect the strings in parallel, and ensure that the combiner box can handle the maximum system current.
Safety Precautions
When working with solar panels, it’s essential to follow proper safety guidelines to avoid electrical shock or other hazards. Wear protective gear, including gloves, safety glasses, and a long-sleeved shirt. Ensure that the system is de-energized before making any connections, and use a multimeter to verify the voltage and current levels. Always follow the manufacturer’s recommendations and guidelines for connecting series panels, and consider consulting a qualified solar installer if you’re unsure about any aspect of the process.
