Frequently Asked Questions
Expert answers to the most common off-grid power questions.
How big of a solar generator do I need to run a refrigerator?
A standard refrigerator uses about 1-2 kWh per day. To run it safely during an outage, you need a solar generator with at least a 1500W output and a 2000Wh capacity, such as the Jackery Explorer 2000 or EcoFlow DELTA Max.
Can a solar generator power a whole house?
Yes, but you need a heavy-duty, expandable system. A single unit cannot power a whole house, but systems like the EcoFlow DELTA Pro can be chained together to provide up to 25kWh of capacity and 7200W of output, which can be tied directly to your home's breaker panel.
What is the difference between LiFePO4 and NMC batteries?
LiFePO4 (LFP) batteries are safer and last much longer, typically offering 3,000+ charge cycles before degrading to 80% capacity. NMC batteries are lighter but usually degrade after 500-800 cycles. We strongly recommend LFP batteries for emergency backup.
