ACOPOWER PTP 100W Portable Solar Panel Expansion Briefcase

The ACOPOWER PTP 100W is a foldable, briefcase-style solar panel built from two 50W monocrystalline cells, sold without a charge controller so it can be added onto an existing off-grid system. It folds flat for storage and transport and sets up in about a minute with pre-installed mounting hardware, making it a practical add-on panel for camping, marine, dry camping, and other off-grid uses. Because it ships without a controller, it's intended to expand an existing solar array via MC4 connectors, up to an additional 100W of capacity, rather than run as a standalone charging system. High-efficiency solar cells and electronic protection against overheating, overcharging, and over-discharging round out the build. It's a good fit for anyone who already has an ACOPOWER kit or another MC4-compatible controller and wants more panel wattage without adding a second controller to the system.
