Quick Answer
A suitable solar setup for extended stays with a Goal Zero Yeti power station includes a 200-300W boulder panel, a lithium battery bank, and a high-efficiency MPPT charge controller. This setup can charge the battery bank efficiently and provide reliable power for the Yeti. A 100Ah lithium battery bank is a good starting point.
Choosing the Right Battery Bank
When selecting a battery bank for extended stays, a lithium battery offers advantages in terms of weight, size, and cycle life compared to lead-acid batteries. A 100Ah lithium battery bank is a good starting point, but consider upgrading to 200Ah or more if you plan to stay off-grid for extended periods. Ensure the battery bank is compatible with the Goal Zero Yeti power station and the solar charge controller.
Solar Panel Selection and Configuration
For a 100Ah lithium battery bank, a 200-300W boulder panel is a suitable choice. Consider using a higher wattage panel, such as a 400W panel, if you plan to stay off-grid for extended periods and have space for larger panels. Configure the panels in series and parallel to achieve the desired voltage and current output. Use a high-efficiency MPPT charge controller to optimize solar charging efficiency.
Charging and Power Management
When using a lithium battery bank, it’s essential to manage charging and power consumption to prevent over-discharge and extend battery life. Use the Goal Zero Yeti’s built-in charge controller and power management features to regulate charging and discharging. Monitor battery state of charge, voltage, and current to ensure safe and efficient operation. Consider adding additional accessories, such as a smart battery monitor and a temperature sensor, to further optimize battery performance.
