Radio Friendly MPPT charge controller for Off-Grid Radio Comms
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.
Off-Grid Grid-Down Comms & Current consumption
The post warns against the use of QRO radio systems for off-grid or grid-down situations due to their high energy consumption. Instead, it advocates QRP radios, suggesting they offer greater efficiency and ease of use with renewable energy sources such as solar. The post also dismisses the idea of lowering the transmission power of QRO radios as a solution, arguing that it does not address issues with energy inefficiency and that such advice is misguided.
