I'm converting a 20ft shipping container into a motorcycle workshop and need help setting up a solar power system that can handle my power requirements. I want to be completely off-grid and run a variety of equipment including lights, fans, a heater, a mini-fridge, a TV, and power tools. I'm unsure about the necessary components and how much solar capacity I'll need. Can anyone provide insights on how many solar panels, what type of batteries, and any other equipment I might need? I'd also appreciate guidance on how to calculate my power demands, especially since I haven't picked out all my gear yet. Thanks in advance!

When it comes to heating, you should definitely think about how cold your winters get. Space heaters can draw a lot of power—almost all their watts convert to heat. If you're in a colder area, consider a mini-split heat pump instead. They’re more efficient and can save energy when heating, but figure out how much insulation your container has first. Also, keep in mind that if you're using an air compressor, check the inverter's surge rating because those can spike really high, around 6000 watts! Let’s make sure you have the capacity covered for those appliances.
Absolutely! Heating and cooling need to be balanced with your insulation strategy. For a workshop like yours, the better the insulation (higher R-value), the less energy you'll use to keep things steady. If insulation isn’t the best, definitely think about adding a space heater or even blankets for localized heating. And when it comes to power supply, a mini-split could work with about 100W running in mild seasons, which is far better than an electric heater. Don’t forget, every appliance you plan to use will affect your total wattage needs, so it’s key to think this through!
100W sounds pretty reasonable for a mini-split, especially if you’re not in extreme temperatures. It's all about finding that balance!
