DIY Solar Battery Bank Design

Designing a DIY Solar Battery Bank requires careful consideration of the specifications and components to ensure optimal performance and functionality. When designing the battery bank, it is important to choose a waterproof ammo box that can accommodate the batteries and protect them from the elements. Additionally, the box should be able to handle the weight of the batteries without any issues. Portability is another important factor, so the battery bank should be easily transportable and take up minimal space when packed for camping trips.

In terms of the components, it is crucial to calculate the compatibility of all the system components. The voltage and amperage of the solar panel should be compatible with other components, such as the charge controller and batteries. Speaking of batteries, sealed lead acid batteries are recommended for their spill-proof operation and ability to be mounted in any position. Connecting two batteries in parallel will provide a larger capacity for longer usage.

To ensure proper functionality, it is important to use a suitable charge controller that can handle the load and solar power. The charge controller should also be compatible with the type of batteries being used. Proper wiring is essential, using appropriate wire gauges and connectors, as well as including fuses for safety. It is also recommended to follow detailed wiring diagrams and parts lists for the different connections to ensure compatibility and efficient operation.

Battery and Solar Panel Specifications

When considering the specifications for a DIY Solar Battery Bank, it is important to carefully select the batteries and solar panels that will provide the necessary power for your camping needs. For the batteries, we recommend using the Mighty Max Sealed Lead Acid, AGM battery. These batteries have a capacity of 12 volts and 18 amp hours or 216 watt hours. They are spill-proof and can be mounted in any position, making them suitable for outdoor use. To maximize the battery capacity, two batteries can be connected in parallel, resulting in a 12 volt, 36 amp hour or 432 watt hour battery. As for the solar panels, we suggest using the Weize 100 Watt Solar Panel. This panel provides up to 5.32 amps at max power and can fully charge the battery in approximately 3 hours and 22 minutes. It is equipped with mc4 male and female connectors for easy installation. By selecting these specifications, you can ensure that your DIY Solar Battery Bank provides sufficient power for your camping adventures.

Charge Controller and Wiring Specifications

To ensure efficient and effective operation of your DIY Solar Battery Bank, it is essential to carefully select a suitable charge controller and establish proper wiring specifications. For the charge controller, I recommend using the ALLPOWERS 20A Solar Charger Controller. This controller can handle 20A of load and solar power, making it suitable for AGM, Open, and Gel type lead acid batteries. It also allows you to set a minimum battery voltage for load power usage. However, please note that it is not compatible with lithium batteries.

When it comes to wiring, use 10 AWG wire for parallel connections and DIY solar panel cord. For connecting the batteries to the charge controller, use 12 AWG wire and include a fuse on the positive side of the battery connection. To connect the charge controller to the socket panel, use 12 AWG wire and make wiring connections with Anderson Powerpole connectors. Following these specifications will ensure a safe and reliable operation of your DIY Solar Battery Bank.
