Meshed PV systems

Manufacturers involved in development and production of control electronics for renewable off-grid energy systems generally offer various types and charge controllers, in the range comprising 2 A to 300A with a system voltage of 12/24/32/36/48VDC (Phocos) and also other products like off-grid inverters, solar refrigerator/freezer, Solar TV, micro turbine, etc. All these products are used in off grid system. For off grid inverter requires a charge controller that controls the charging of the batteries and an inverter that converts the DC power from the solar panels and the batteries into AC power. These systems normally provide a small amount of power due to the cost of larger systems. Plans are to introduce solar micro-inverter which converts direct current generated by single module to renewable power. The output from several micro-inverters is combined and fed to electrical grid. The main advantage of micro-inverters is small amounts of shading, debris or snow lines on solar module do not disproportionately reduce the output of the entire array. Each micro inverter of harvests optimum power by performing MPPT system for its connected module. The design of the system is simple, safe and simplified management.
