Micro grid system and off-grid wind solar street lamps light fixed voltage

1, the common possess independent power supply features; All need energy storage system; All need to match the best capacity battery. 2, the difference between micro grid system belongs to the active system, can be connected to the power grid and off-grid photovoltaic power generation systems belong to the passive system, with large electric

1. The power of the ordinary both have independent characteristics; Need energy storage system. It is necessary to match the best battery capacity. 2. Differences between micro network system is a system actively, can access to the large power grid. Off-grid photovoltaic power generation system is a passive system, can't access power grid. Micro grid system is more complex, need to configure the more distributed power supply. Off-grid photovoltaic power generation systems need only controller and off-grid inverter. Micro grid system of the energy storage system is a four quadrant converter can realize two-way flow of energy. Off-grid photovoltaic power generation system of single-phase converter, energy storage system is not realize two-way flow of energy. 3. Principle of practical application if the application is relatively remote place such as gobi, beach, artificial maintenance, does not need frequent off-grid photovoltaic power generation system is suitable, so the system does not need to be manned, can run independently, only need regular maintenance batteries. If applied close to the power grid and require frequent manual maintenance and scheduling requirements strictly, micro grid system is preferred, because of all kinds of distributed power switch and the system operating status of scheduling need manual intervention, and some even need to monitor and control system.
