Open in editorThis multi-panel solar array demonstrates how to scale up from a single panel to a 600W system. Three 200W panels wire in parallel to a 60A MPPT controller, which charges two 200Ah lithium batteries wired in parallel for 400Ah total capacity. A bus bar distributes power from the main fuse to a 2000W inverter, lights, and a fridge.
Parallel wiring keeps the voltage at the same level as a single panel while multiplying the current output. The 60A MPPT controller handles the combined output efficiently, and the dual battery bank provides multi-day autonomy. The bus bar keeps positive distribution clean and organized, making it easy to add more circuits later. This is the go-to setup for serious off-grid solar installations.
