Description of this On grid String inverter HC16KTSI
 
Hua Cheng's inverter is a string inverter, which is mainly suitable for small and medium-sized rooftop photovoltaic power generation systems and small ground power stations. The main advantages of our power inverter module use for of the solar photovoltaic power generation grid-connected system are:
(1) The string inverter adopts a modular design, each photovoltaic string corresponds to one inverter, the DC terminal has the maximum power tracking function, and the AC terminal is connected in parallel, which has the advantage that it is not subject to the difference between the modules. The effect of shadow occlusion, while reducing the optimal operating point of the PV module and the inverter does not match, maximizing the amount of power generated.
(2) The string inverter has a wide MPPT voltage range, generally 250-800V, and the component configuration is more flexible. In the rain
The area with a lot of fog has a long power generation time.
3) The string-type grid-connected inverter is small in size, light in weight, easy to handle and install, and does not require professional tools.
And equipment, and no need for a dedicated power distribution room, can simplify construction, reduce floor space, DC line connection, and do not need DC combiner box and DC power distribution cabinet in various applications. The string type also has the advantages of low self-consumption, low impact, convenient replacement and maintenance.

The inverter of the solar photovoltaic power generation grid-connected system usually adopts a current control mode, so that the whole system system is actually a system in which a voltage source and a current source are connected in parallel. The main control objective of the inverter connected to the grid is to ensure that the inverter output current is in phase with the common grid voltage, and that the grid voltage can be tracked in real time to achieve maximum power tracking control. By adopting the phase-locked control technology, the grid-connected current output from the solar photovoltaic power generation grid-connected system is synchronized with the voltage of the public grid voltage to ensure that the power factor of the system output is 1. When the PV grid-connected inverter is running, it is necessary to control the total distortion of the grid-connected current to be low, so as to reduce the harmonic influence on the grid and maximize the active power output of the grid-connected system.
