Microinverter refers to an inverter that can track the maximum power point of each PV module individually, and then merge into the AC power grid after inverting, so as to realize the refined adjustment and monitoring of the output power of each PV module. Microinverters are mainly used in small and medium-sized solar power stations such as distributed PV and BIPV buildings.

Safety: 

 There is 600-1000V high DC voltage in the solar array, modules are connected in series in traditional string solar systems. It's easy to arc and cause naked flames, accompanied by a high temperature of 4000 degrees. Under this high temperature, the steel structure softens, the walls crack, and the glass melts, causing the building to catch fire and collapse. The microinverter technology adopts a fully parallel circuit design, there is no voltage superposition between PV modules, and the DC voltage is less than 60V (not higher than the maximum output DC voltage of PV modules), which completely solves the fire risk caused by high-voltage DC arcing, and at the same time It also solves the problem that when the house catches fire, the DC high voltage on the roof hinders the rescue.  

More power generation:

It's inevitable that there are factors such as occlusion, attenuation, shadow, dust, mud, bird droppings on the rooftop solar power plant, etc., resulting in a serious power degradation of some PV mocules. In the traditional system, the modules are connected to the DC input of the string inverter after being connected in series. The failure or power degradation of one PV module will greatly reduce the power output of one string. In the microinverter system, there is no series connection between the modules. The microinverter has an independent MPPT for each module to ensure that each PV module outputs at the maximum power. When the output power of a certain PV module drops seriously, it does not affect the maximum power output of other PV modules.

Reduce O&M costs: 

Through the Mocowini Cloud platform, the operation data of each module in the system can be obtained, such as voltage, current and power. Once there is a malfunction, it can be quickly located through the Mocowini Cloud, which greatly saves manpower and material resources.

High Reliability: 

 The design life of the Mocowini microinverters is 25 years. As part of the ISO9001 certification process, all products have to go through countless strict quality inspections, reliability verification tests and accelerated life simulations, such as high and low temperature test, salt spray test, waterproof test, drop test, and vibration test. In addition, Mocowini also entrusts recognized third-party test institution to meet industry standard requirements.

Flexible expansion and transformation

In the system using microinverter, the microinverter is integrated with the PV module, which can realize modular design and plug-in & play. The microinverter is small size, basically does not occupy the installation space and easy to install, and can make full use of the space and adapt to applications with different installation directions and angles. In addition, the use of Mocowini microinverters makes the expansion and transformation of the rooftop easier, and the quantity of microinverters can be selected completely according to the expansion needs.

Module Level Power Electronics. In solar PV systems, power electronic equipment that can finely control single or several PV modules to realize functions such as inverter, monitoring, power optimization, and rapid shutdown. This technology includes power electronics, semiconductor device, communication, cloud computing, and highly high-end manufacturing. The current product series includes microinverter, optimizer, and module-level rapid shutdown switch.

Yes, they can. Because each microinverter has at least 2 independent MPPT(Maximum Power Point Tracking) channels. Therefore, if PV modules of one MPPT have a different specification from others, it will not affect the normal operation of the other modules connected to the same microinverter.

We recommend that the over-sizing ratio be between 1.1 and 1.35 depending on your solar project.

The Mocowini database and smart O&M software system are independently developed by Mocowini. It's a PV smart O&M platform integrating functions such as real-time monitoring, intelligent alarm, statistical analysis, and remote upgrade control. As long as there is a network, users can log in to the platform through website or APP,  real-time monitoring the operation of each module in the system to achieve rapid fault location. According to the different needs of installers and end users, the Mocowini smart O&M platform provides different levels of account data to fully meet customer needs and promote the digital and intelligent development of photovoltaic.
