Temat: Solar AC Micro Inverter - for single 200-300W PV module
Specifications1 Low-cost & easy installation
2 IP65 protect
Advantages
1 More Power
>> No imbalance losses due to differences in PV output voltage or current.
>> Microprocessor-controlled Maximum Power Point Tracking (MPPT) operates over entire DC input voltage range.
>> Significantly decreases system power reduction events due to single-module shading.
2 Low-cost, Easy & Flexible Installation
>> 50% reduction in wiring -micro inverter needs little DC side wiring.
>> No large or heavy inverters to ship, handle, or mount.
>> Simplified system assembly - AC wiring connects directly to AC sub-panel with appropriate breaker.
>> Minimizes system design time and expense – no need to install side by side or face the same direction.
>> Incremental growth capability - each system can be rearranged or upgraded with more panels when needed.
3 More Reliable
>> Single failure does not disable entire system.
>> Anti-islanding protection built into every module.
>> Eliminates series connection problems, where one defective component can affect entire system.
>> PV panel is not exposed to high voltage - eliminates arching problems.
>> Have much higher durability than conventional string/central inverter.
Disadvantages
Initial Cost & Maintenance
1 Initial Cost
The equipment initial cost per watt is a little higher than the equivalent power in a central inverter.
2 Maintenance
Micro inverter normally located near the panel, where it may be harder to maintain if it installs on the top roof.
