A prewired cable entry plate on an RV is a simple way to have your RV solar-ready without the need to run additional wires into the RV. The main 10AWG cable run uses a quick-connect MC4 connector base for both the + (Red) and – (Black) cables.
A solar charge controller is the brains of a charging system. The solar controller determines when and how the solar panels charge your batteries based on several factors. This protects your batteries from being overcharged from your solar kit.
Batteries are the lifeblood of an RV off-grid power system because they store the power needed at times when there is no power plug. RV batteries are available in a variety of types and common voltages like 6 Volt and 12 Volt.
The wires on your solar panels are like the water pip[es in your home, but instead of carrying water, they carry the electricity you need to charge your batteries and power your devices. Wire gauges and connectors vary by system.
