Depending on the model, most units generate between 10,000–20,000 watts per day using high-efficiency solar panels. The battery storage can hold over 20Kwh to 30Kwh.(with the expandable 30K Bank). This is enough to run LED lighting, laptops, power tools, internet routers, ventilation systems, and basic appliances (like a mini-fridge or microwave), along with charging stations for tools and devices.
