Since the goal of "dual carbon" was set, distributed photovoltaic has been favored for its advantages of low carbon emission reduction, diversified application scenarios and easy return on investment. However, with the rapid increase of the installed capacity, there are also many pain points in the market, such as DC high voltage, barrel effect, operation and maintenance difficulties...... This leads to security concerns and a lack of desired return on investment for end users.
For the above pain points, Wo Mai micro inverter can be easily solved. Now, we combine the current market dilemma, in-depth analysis of Wo Mai micro inverse solution, to find out.
01
Market pain point # 1: Security
In recent years, household photovoltaic fires are frequent, 80% of which are caused by DC arc caused by traditional inverter DC high voltage. Moreover, such photovoltaic systems are usually installed on the roofs of homes or factories. Once fire or explosion occurs, it will bring immeasurable property losses and even endanger lives.
In addition, there are still hundreds or even thousands of volts of DC in the combustion system. If firefighters rush to the rescue, it can have tragic consequences. As a result, first responders often have to wait for the plant to completely burn down before they can begin their work, which often leads to significant delays in firefighting efforts.
Scheme 1
Low voltage safety, no fire hazard and electric shock risk
Hemai micro inverter is connected to the photovoltaic system in parallel, making the DC side of the system stable at about 40V low voltage, from the root to eliminate fire hazards and electric shock risk. We don't have to worry about a DC arc fire at a micro-retrograde power plant.
Even if the micro inverter system has an emergency due to external factors, after shutting down the system, the first responders will not face the risk of electric shock because there is no DC high voltage in the PV plant.

Market pain point 2: the barrel effect
Each photovoltaic panel has different output characteristics, such as current, voltage and optimal operating point. This inconsistency will become more apparent as photovoltaic systems are used outdoors for a long time and age naturally. The power generation characteristics of the traditional photovoltaic system are very consistent with the "wooden barrel effect" : the traditional photovoltaic system is designed in series, and the total power generation of a series of photovoltaic panels depends more on the output characteristics of the weakest photovoltaic panel in the series, which means that the "weak" will definitely drag the team down and affect the power generation revenue.
Option 2
Component-level MPPT technology eliminates the barrel effect
In view of the "cask effect", Wo Mai micro reverse medicine. Its component-level MPPT controller tracks the maximum power point of each PV module separately. Even if one PV module is not operating efficiently, it will not affect other PV modules. For example, in the entire photovoltaic system, if a component is damaged or blocked, the maximum power point tracking controller of other components will continue to maintain their maximum capacity efficiency.
