High Efficiency
2 MPPT design, Tracking accurate up to 99.9% can make BLD-20k-TL series inverters work more flexible and effective. All rooftop modules areas could be used for generating , it also could minimize the capacity consumption due to shade hiding. Max. Efficiency is up to 98.2%, Euro efficiency 97.8%, which means more transmission power than others solar device. BLD photovoltaic inverter is your most wise choice.


High Stability
BLD inverter high quality casing can provide the best protection for insider electronic components, Besides, by IP65 protection, it can be installed and run safely in the indoor and outdoor. Not afraid of any bad environment, it always creates a best working condition for you.


Innovative & Smart Monitoring
Wifi cards inside setting is the the first Invention of the world, and power management box could preserve all important record from sensor. Each inverter are equipped with RS485, RS232, USB and Ethernet interface, wifi kit and GRPS Kits as your option. Through our free monitoring software to connect with your PC/Mobile, you can view the PV station output data and pubic grid power supply.


Good Heat-dissipation, Low Noise
BLD-20k-TL series inverter with special designed intelligent cooling system , can still maintain excellent heat dissipation in a hot environment, always play the best performance. while sensor monitor operating temperature ,smart cooling system will help heat effectively discharged outside from the shell. Then you no longer need to fan, for you to save money at the same time also brings a quiet and comfortable environment
