The Renogy 200W Solar Starter Kit is easy for you to install, and it is the most economical choice for solar beginners. This Renogy Solar Kit includes the equipment necessary for building a new system: a solar panel, a charge controller, needed electrical wiring, Solar Y Branch Connectors and Z-brackets, making it an ideal choice for both off-grid and mobile solar power applications. This Starter Kit will produce an average of 1000Wh of electricity per day (Based on 5 hours of direct sunlight conditions). The 100W solar panel doesn’t take up much roof space, but its energy can offset loads such as lighting, camera, and projector. With the Wanderer Li 30A PWM Charge Controller, the kit can meet your further power needs by adding more of the same solar panels to expand up to 400W. The Starter Kit can build a reliable and environmentally friendly power supply, perfect for RVs, campers, boats, sheds, and cabins. It can also be installed as a power supply for outdoor appliances and emergencies, and as a stand-alone power system.
