Off-grid PV systems, as the name implies, are systems that are not connected to the utility grid. These systems require an energy storage system for the energy generated because the energy generated is not usually required at the same time as it is generated.
A typical 3kw residential off grid solar power system comprises the following main components:
11 pcs Solar PV Modules: these convert sunlight directly to electricity
1 pcs 3kw off grid inverter: converts the DC current generated by the solar PV modules to AC current for
1 pcs Charge Controllers: manage the charging and discharging of the batteries
4 pieces 12V 250AH (adjustable) batteries: Stores the energy generated by the PV modules Mounting support and cableChina Off Grid Solar Power System
