System Monitoring
The user just needs to simply connect the power cable to the indoor socket, and the Ethernet network
cable to the computer, the Meikai Messenger will upload the whole operating data of the Micro-inverter
to the web server. Both current and historical operating data can be accessed through the Megawatt
website. The user will also quickly detect if the system is not running properly.
System Reliability
It is commonly recognized that Micro-inverter system is more reliable compare to traditional central or
string inverters due to its original design concept. The distributional power output Micro-inverter system
eliminates single point failure. The Meikai Micro-inverter is designed to operate without power loss when
ambient temperature is 65°C. The enclosure protection rating of Meikai Micro-inverter is IP65 to
undergo any weather condition.
Simplified System Design
Meikai Micro-inverter system makes it is extremely simple to plan or design a solar system, no
complicated string calculation needed, no certain number, model, tilt demanded, no cumbersome
central or string inverter requested, each of the Meikai inverter will be easily mounted on the rack under
the module, the DC wire from the module directly connect the Meikai Micro-inverter simply with quick
terminals, no risk of 600V or higher voltage electricity shock.
Electrical Compatibility
At this moment, the Meikai N220/N300 Micro-inverter matches only with most modules with 72 cells with
proper voltage and current range. The Meikai Micro-inverter shall be connected to the utility grid with
voltage range from 205V to 253V and frequency of 50Hz. Depends on the two different ways of
installation, 14 units are allowed in a branch if the N220 Micro-inverters are connected in series, 11 units
are allowed in a branch if the N300 Micro-inverters are connected in series, if a busbar is used, the
number of units is depending upon the wire diameter.
