OH8STN Portable Ham Radio on Solar Power GIVEAWAY 2024.

The author discusses choosing a solar charge controller suitable for radio communication. He focuses on three criteria: portability, radio frequency quietness, and Maximum Power Point Tracking (MPPT) functionality. Recommending Genasun due to its compatibility with these requirements, he mentions his dissatisfaction with another brand, Victron, that caused excessive radio frequency noise. For optimal results, he suggests keeping devices DC powered and using no inverters. He provides specific instructions about matching controllers to battery and solar panel specs, and suggests parallel configuration for Genasun controllers.
