The Rich Solar RS-K3004 is a 300W DIY solar charging kit without a battery for RVs, boats, trailers, campers, cabins and small off-grid battery systems. It includes three MEGA 100 100W monocrystalline solar panels, one BRAVO 40 40A MPPT solar charge controller, red and black panel-to-controller cables, red and black controller-to-battery cables, three Z-bracket mounting sets and one 10A inline fuse holder with fuse. The included panels provide 300W total rated solar output, while the controller supports 12V or 24V auto operation with compatible lead-acid and lithium battery selections. This kit can be paired with an appropriate separately selected battery, including compatible 12V lithium battery setups, but the battery itself is not included. Battery selection, panel layout, cable routing, fuse placement, weather protection and final system setup should be verified for the exact installation.
The RS-K3004 is built for small solar charging projects where multiple compact panels, a larger MPPT controller and core wiring are needed. It is a practical starter package for users who already have a compatible battery or plan to select one separately. It does not include a battery, inverter or full enclosure system.
The kit includes three MEGA 100 panels, each rated at 100W, for 300W total rated photovoltaic capacity. Each panel is a 12V off-grid solar panel with 0~+5W guaranteed positive power output, IP67 rating, tempered glass, an aluminum frame and pre-drilled mounting-hole compatibility.
The included BRAVO 40 controller uses maximum power point tracking charging technology with tracking efficiency above 99.5% and charge conversion efficiency as high as 98%. It supports 12V or 24V DC system self-adaptation and battery type selections for compatible lead-acid and lithium battery setups.
The RS-K3004 includes 20-foot red and black #10 gauge solar cables for connecting the panels to the controller, 10-foot red and black #8 gauge battery cables for connecting the controller to the battery, three Z-bracket mounting sets and one 10A inline fuse holder with fuse. Final cable routing, strain relief, fuse placement, battery connection, mounting surface and weather exposure should be verified before installation.
The RS-K3004 combines three 100W panels with a 40A MPPT controller for planned RV, boat, trailer and small off-grid charging setups.
Included #10 solar cables, #8 battery cables, Z-brackets and a 10A inline fuse holder support planned panel-to-controller and controller-to-battery installation.
