Quick Answer
For Renogy solar setups, the optimal battery type is a deep cycle lead-acid battery, such as the Renogy Deep Cycle AGM Battery, with a capacity of 100-200Ah, suitable for both RV and cabin systems.
Choosing the Right Battery Size
When selecting a battery for a Renogy solar setup, consider the size of your system. A general rule of thumb is to choose a battery with a capacity of 100-200Ah for a small to medium-sized system, and 200-400Ah for a larger system. This will ensure that the battery can handle the energy storage needs of the system, without being too large or too small.
Battery Type Considerations
Deep cycle lead-acid batteries, such as the Renogy Deep Cycle AGM Battery, are a popular choice for solar setups due to their durability and cost-effectiveness. These batteries are designed to handle the deep discharge cycles associated with solar energy storage, and can be charged and discharged multiple times without losing their capacity. When choosing a deep cycle battery, look for one with a high cold cranking amp (CCA) rating, such as 400-600CCA, to ensure reliable starting power.
Wiring and Charging Considerations
When wiring and charging your Renogy solar setup, make sure to follow proper safety protocols to prevent damage to the battery and other components. Use a Rover charge controller, such as the Renogy Rover 40A Charge Controller, to regulate the charging process and prevent overcharging. Connect the solar panels to the charge controller, and then connect the charge controller to the battery using a thick, 10-gauge or 6-gauge wire, depending on the distance between the components.
