Once again, I put out the question about another battery build. The votes point to a smaller, lighter pack. Well, on October 04 2017, parts […]
Quite often I sit out here at a nice spot along the sea enjoying the final moments of the summer/autumn. Even with the sun quite […]
Earlier today, I put out this picture on instagram, and included a question. “Who would like to see the step by step build video?”. Seriously didn’t […]
OH8STN Portable Ham Radio on Solar Power GIVEAWAY 2024.
The off-grid ham shack is fully energy self-sufficient, utilizing solar, wind, and other power sources, with a focus on low current devices for sustainable communication.
Integrating the Ruuvi Gateway and sensors to remotely monitor indoor/outdoor temperatures, ensuring safe temperatures for lithium battery charging.
Off-Grid Ham Shack
To protect lithium batteries from cold while charging, a video/blog showcases using a Chinese diesel heater in an off-grid ham shack. It’s vital to keep batteries above freezing, a lesson learned from electric cars in winter. The video details the installation and operation of a 3kw Vevor diesel heater, which also powers up using the ham shack’s LiFePO4 batteries, maintaining ideal temperatures for both batteries and equipment.
This tutorial demonstrates how to connect two 12-volt batteries in parallel using Power Queen 12.8V, 100Ah, 1280Wh lithium iron phosphate batteries. The provided YouTube link offers a detailed guide. For related content, explore building a solar-powered Off-Grid Ham Radio Station and information on radio-friendly MPPT charge controllers and off-grid communications.
The Off-Grid Ham Shack series discusses creating a self-sufficient ham radio station or ‘Ham Shack’ capable of operating on solar power during any grid down scenario, emphasizing the importance of an energy strategy for off-grid communications. This system includes solar panels, a charge controller, battery, and power distribution system. Key elements are the use of photovoltaic (PV) panels to harness solar energy, a solar charge controller to regulate energy flow and prevent battery overcharging or damage, and a battery to store energy for later. As well, power distribution ensures the allocation of power to multiple devices simultaneously. A grid-down energy strategy is crucial to any communication-related emergency, be it CB, FRS, GMRS, MURS or PMR radio, UHF CB, DMR, DStar, Meshtastic or LoRa communications.
