ROCKSOLAR 400W Rigid Solar Panel Kit with 40A MPPT Charge Controller

The kit contains two 200W 12V rigid solar panels, a 20A MPPT solar charge controller, necessary connecting cables, mounting hardware, and a user manual for a complete solar energy system setup.

Yes, the included 20A MPPT controller is versatile, capable of supporting various battery types such as Lithium, AGM, Gel, and lead-acid, providing flexibility for different energy storage needs.

The 20A MPPT controller enhances solar energy conversion efficiency significantly compared to PWM controllers. It maximizes the energy harvested from the solar panels, ensuring efficient battery charging.

The 400W solar panels are built to withstand various environmental stresses, including high temperatures. They are designed to offer consistent performance and durability across different climatic conditions.

Each 200W solar panel in the kit typically requires about 1580mm x 808mm of space, so for the full 400W, ensure you have double this area available for an unobstructed installation.

Indeed, the MPPT controller is designed to charge batteries efficiently and safely, helping to prolong their overall lifespan by preventing overcharging and ensuring optimal charging profiles.

Yes, this kit is perfect for off-grid setups, including remote cabins, RVs, and boats. It provides a reliable and sustainable power source in areas without access to the electrical grid.

Maintenance typically involves periodically cleaning the solar panels to remove debris, dust, and snow. Regular inspection of the mounting system and electrical connections for safety and efficiency is also recommended.

Solar panels can last more than 25 years with proper care and maintenance. The MPPT controller and other components generally have a shorter lifespan but should function effectively for several years with proper usage.

Yes, the 400W solar panel kit contributes to sustainable and renewable energy use, significantly reducing carbon footprint and reliance on fossil fuels for energy generation.

Ensure all electrical connections are secure and the panels are solidly mounted. Always follow the safety guidelines provided in the manual. If you're unfamiliar with solar installations, professional installation is recommended for safety and optimal performance.

While solar panel output naturally decreases in cloudy conditions, the MPPT controller optimizes the available solar energy, ensuring that the batteries receive the maximum possible charge even on overcast days.
