Quick Answer
The Solar Wise E300LFP and E500LFP share the same 600W output and the same UPS features; the main difference is battery capacity: 288Wh for the E300LFP versus 576Wh for the E500LFP — exactly double. If you only need to back up low-power devices like a modem, router, or laptop, the E300LFP is enough. If you need to run higher-draw appliances like a refrigerator for longer, or want all-day power for camping or a small business, the E500LFP is the better fit.
