solar inverter 3kw 12v to 220v

The operating voltage range of the inverter is related to the electrical topology of the inverter and the output voltage of the inverter. The string inverter and the collector-distributed inverter are two-stage electrical topology, and the MPPT operating voltage range is 250-850V Among them, the centralized inverter is a single-stage structure, with output voltages of 270V, 315V, 400V and other specifications, input MPPT voltage ranges are 450-850V, 500-850V, 570-850V, etc., and there is a single-stage structure There are only one-stage DC-AC inverters in the string inverter, the output voltage is 400V, and the MPPT input voltage range is 570-850V. From an application point of view, each has advantages and disadvantages.

1) From the perspective of the inverter, the higher the output voltage of the inverter, the lower the current and the higher the efficiency of the same power level. Single-stage has simpler structure than double-stage, high reliability, low cost and low price.

2) From a system perspective, the wider the inverter MPPT voltage range is, the earlier it can be started, the later it will stop, and the generation time will be longer.

3) According to the principle of voltage source series connection, the output voltage of the system is added, and the current remains unchanged. After photovoltaic modules are connected in series, the output current is determined by the least number of panels. 

Affected by the raw materials, processing techniques, shadows, dust, etc. of the modules, the power of one module will decrease, the power of this series of modules will be reduced, so the number of modules in series should be as low as possible The number of parallel connections is as small as possible to reduce the impact caused by the consistency of the components.

Built-in MPPT solar controller for maximum power point tracking , the efficiency is up to 99%.systemPure sine wave inverter for use with Lead Acid or Lithium Batteries.  The full bridge rectifier and manboard structure are highly optimized.Input and output circuits are isolated.
