Video: Working Principle of 3kW-5kWh Integrated Solar-Storage-Charging System
This diagram shows the topology of a 3kW-5kWh integrated solar-storage-charging system. Five 585W PV panels deliver DC power to the all-in-one energy storage unit, which connects to both the grid and household loads. The system prioritizes solar power and stores surplus power in the battery. It automatically switches to off-grid mode during grid failures to supply residential loads, ideal for suburban homes with unstable power supply.

Technical Solution for 3kW-5kWh Solar-Storage-Charging Integrated Grid-Tied/Off-Grid Power Supply for Suburban Residential Buildings in Lusaka
Power grids in suburban Lusaka, Zambia are poorly built and unstable, causing frequent outages, voltage fluctuations and maintenance blackouts that disrupt household lighting and appliances. To address these issues, this project adopts a grid-tied/off-grid residential PV energy storage system. The all-in-one storage unit supports municipal power and diesel generator backup charging to enable complementary power supply from PV, battery storage and backup power sources.
