Basic residential energy storage solution (suitable for average families of 3-5 people)

1. Scenario Pain Points Ordinary households generally face problems such as high electricity costs caused by peak-valley price differences, disruption to daily life caused by sudden power outages, and low self-consumption rate of distributed photovoltaics. 2. Core Configuration Battery type: Lithium Iron Phosphate (LFP) Capacity range: 5kWh-15kWh Rated power: 3kW-5kW Cooling method: Air cooling Functional support: APP remote control, intelligent peak-valley arbitrage, seamless grid-connected/off-grid switching 3. Expected Benefits Peak-valley electricity price arbitrage can save 30%-50% of electricity bills annually With household PV, the self-consumption rate can be increased to over 80% It can ensure basic household electricity consumption (lighting, refrigerator, router, etc.) for 8-12 hours during power outages System service life ≥10 years, payback period 4-6 years 4. Applicable Scenarios Ordinary residential buildings, households with installed or planned household PV, areas with general grid power supply stability.
