For most people, the EcoFlow Delta 2 offers the best balance of capacity (1kWh), power output (1800W), and expandability. It can power essential devices for hours and recharge via solar, AC, or car charging.
A typical refrigerator uses 150W continuously. A 1kWh solar generator would power it for about 6-7 hours. For 24-hour backup, consider a 2kWh+ system with solar charging capability.
Solar generators are quieter, need no fuel, and work indoors, but have limited runtime. Standby generators provide unlimited power but require gas/propane and professional installation. Most homes benefit from both for different scenarios.
Yes, solar generators store power in batteries and work day or night. They can be charged via solar panels, wall outlets, or car chargers. Solar charging is just one of multiple charging options.
Calculate your essential loads (lights, fridge, communication, medical devices). Most families need 1-3kWh capacity for 12-24 hours of basic power. Start smaller and expand rather than over-buying initially.
β‘ Quick Power Calculator
Refrigerator (24h)3.6 kWh
LED Lights (10h)0.5 kWh
Router + Phones0.5 kWh
Daily Essentials~4.6 kWh
Recommendation: 2kWh+ system with 400W+ solar for daily recharge
