Microinverter

Microinverters are extremely well-suited for residential solar power systems and have been widely adopted both domestically and internationally.

①Space-Saving and Aesthetic: Unlike traditional inverters, microinverters are attached directly to the back of the solar panels, not only adding a high-tech appeal but also saving home space.

②Safety: Microinverter systems use a parallel circuit design, eliminating the high-voltage DC electricity present in series systems on rooftops. This reduces the risk of fire caused by high-voltage DC arcing, making them safer for residential rooftops.

③Increased Efficiency: The parallel circuit design of microinverter AC systems means that partial shading, dust, or leaves on solar panels do not create a bottleneck effect. This eliminates mismatch issues caused by different orientations and angles of the panels, significantly increasing power generation by 5% to 25%. This makes them ideal for applications in urban villas and new rural homes.

④Real-Time Monitoring: Microinverters come with WiFi communication capabilities, allowing real-time monitoring of parameters such as power output (voltage, current, frequency) and device temperature for each solar panel. Using WiFi, this information is uploaded to global servers via the internet, enabling users to monitor the performance of each solar panel from anywhere with an internet connection.

⑤Flexibility: The parallel design feature of Envertech microinverters allows each solar panel to operate independently. This provides great flexibility for disassembly, modification, and expansion of balcony spaces and rooftops.

If you are undecided about which of these three types of microinverters to choose, you may need to consider the following questions:

①Is the installation time tight?

The wiring for each 4-in-1 series microinverter is slightly more complex, so the installation time for a single unit is a bit longer. However, installing one 4-in-1 series microinverter generally takes less time than installing four 1-in-1 series microinverters.

②Are you looking for a more cost-effective option?

In most cases, purchasing one 4-in-1 series microinverter is more economical than buying four 1-in-1 series microinverters. Installers sometimes worry that connecting all the PV modules around a 4-in-1 series microinverter might require more DC extension cables, increasing costs.

Often, installing a 4-in-1 series microinverter doesn't require any additional DC extension cables. Even if it does, DC extension cables are typically affordable, and the overall cost of installing a 4-in-1 series microinverter is generally more cost-effective.

③When is the 1-in-1 series microinverter more suitable?

In some situations, the 4-in-1 series microinverter may not always be the best choice, such as when the PV system uses AC modules.

Additionally, if the roof cannot accommodate more than two or three PV modules, there is no need to install a 4-in-1 series microinverter. In such cases, the 1-in-1 or 2-in-1 series microinverter is more appropriate.

Moreover, the 4-in-1 series microinverter needs to be installed close to the PV modules it connects to. In most cases, this is not an issue; but if the roof structure is very complex, such as having an irregular shape or many protruding vents and chimneys, installing a 4-in-1 series microinverter might not be feasible. In such cases, the 1-in-1 or 2-in-1 series microinverter is more suitable.

Introducing a Concept:

①High Voltage DC: Photovoltaic systems using string/centralized inverters have each string composed of several or even dozens of solar modules connected in series, resulting in 600V-1500V of high voltage DC in the system. High voltage DC is the direct cause of DC arcing. According to relevant data, DC arcing accounts for 52% of photovoltaic fire causes.

②Safety of Microinverter Technology: Microinverter technology employs a fully parallel circuit design, eliminating voltage stacking between modules. The DC voltage is less than 60 volts (not exceeding the maximum output DC voltage of the module), completely mitigating the risk of fires caused by high voltage DC arcing. It also addresses the issue of photovoltaic systems obstructing rescue efforts in the event of a house fire.

After preparing the necessary documents, homeowners submit a grid connection application to the local customer service center of the State Grid Corporation. Upon approval, the grid operator installs a smart meter, signs a power purchase and dispatching agreement, completes grid connection inspection and commissioning, and ultimately enables grid-connected electricity generation.
