Equipment Type and Primary Applications: 520W Slim Kit

The 520W Slim Kit is a solar battery-charging system for RVs, vans, trailers, boats, tiny homes, and other off-grid installations. It combines four 130W slim monocrystalline solar panels with a 40A MPPT charge controller and pre-assembled connection hardware for compact rooftop solar applications.

Performance Specifications

  • Solar array: 520W total, comprising 4 × 12V 130W RS-M130SL slim monocrystalline panels.
  • Estimated energy production: approximately 1.9kWh per day under 4 peak sun hours.
  • Charge controller: Bravo 40 RS-MPPT40PB, 12V/24V, 40A MPPT.
  • MPPT tracking efficiency: up to 99.5%; peak conversion efficiency: 98%.
  • Electrical connections include a 30ft 10 AWG panel-to-controller cable set and a 10ft 8 AWG controller-to-12V-battery cable.

Safety Features and Certifications

  • Includes a 20A solar panel inline fuse holder, RS-SC20F.
  • Mounting Z brackets and dedicated cable assemblies support organized panel installation and battery connections.

Installation and Maintenance Requirements

Installation requires suitable rooftop or mounting space for four slim solar panels, a compatible 12V battery system, and secure access for the controller and cable routing. Connect the solar array to the Bravo 40 controller using the supplied cable set and Y branch parallel adapter, then connect the controller to the battery with the supplied 8 AWG cable. Secure panels with the included Z bracket set. Periodically inspect panel surfaces, cable insulation, fuse connections, and mounting hardware.
