Solution na Off-Grid Backup Power: Analysis Detai na Battery Energy Storage Systems na Residential
Daga baya na households na bi tradishinala yana amfani da shi don zama da tashar karkashin kuli a lokacin da grid ta faru?
Architecture na Solution:
Kompojentoci Mai Karamin
Battery na Energy Storage (LiFePO4/LFP)
Inverter na Off-Grid (da Grid-On/Off switching function)
System na Intelligent Energy Management
PV Charge Controller (MPPT technology)
Workflow na System
A Lokacin da Grid Yana Cikin Tsarin:
PV Generation → Home Consumption → Battery Storage → Excess Power Fed to Grid
A Lokacin da Grid Ta Faru:
PV Generation + Battery Discharge → Through Inverter → Powers Critical Loads
