Off-grid solar architecture is characterized as having no connection to the grid and as having a single battery or an array of batteries to supply the load when solar energy is not present. This system is composed of three main functional blocks.

  • The junction box, present in each solar panel, implements the essential bypass functionality.
  • The MPPT charge controller implements the DC-DC power conversion with MPPT and battery charge capability.
  • The inverter implements the power conversion stages (DC-DC and DC-AC) and the communication capability.

The block diagram will help you make the right choice for each functional block from a wide range of recommended products..
