The U B Series central photovoltaic inverters are able to manage a greater amount of power per power block.
The U B Series inverters integrate an innovative control unit that runs faster and performs a more efficient and sophisticated inverter control, as it uses a last-generation digital signal processor. Furthermore, the hardware of the control unit allows some more accurate measurements. These PV inverters feature a lower power consumption thanks to a more efficient power supply electronic board.
The U B Series solar inverters feature an improved AC output busbar in order to facilitate the on-site inverter-to-transformer connection. These three-phase inverters are equipped with a motorized AC circuit breaker and a motorized DC breaker to decouple the PV generator from the inverter. Optionally, they can be supplied with DC fuses, grounding kit and input current monitoring.
This inverter series has been designed to comply with the grid connection requirements UL1741, IEEE1547 and RULE21. They feature low voltage ride-through capability, they can control the active power delivered to the grid and they can also deliver reactive power.
