Solar power generation system with power Optimizer can greatly improve the conversion efficiency, and the Inverter (Inverter) function simple to reduce cost. For a smart solar power system, a power optimizer is installed to ensure the optimal performance of each solar cell and to monitor the state of cell depletion at any time. The power optimizer is a device between the power generation system and the inverter, the main task is to replace the original optimal power point tracking energy of the inverter. By simplifying the circuit and matching a single solar cell to a single power optimizer, the power optimizer performs a very fast, analogically optimal power point tracking scan, so that each solar cell can achieve the exact optimal power point tracking. In addition, it can also monitor the status of the cell anytime and anywhere by placing a communication chip. The immediate return problem allows the relevant personnel to repair as quickly as possible.
