Abstract

A power system includes a plurality of DC/DC converters and a DC/AC inverter. The plurality of DC/DC converters having outputs electrically connected in parallel for supplying a DC voltage bus to an input of the DC/AC inverter. The plurality of DC/DC converters each include a maximum power point tracker (MPPT). Various DC/DC converters and DC/AC inverters suitable for use in this system and others are also disclosed.

Claims

exact text as granted — not AI-modified
1 - 12 . (canceled) 
     
     
         13 . A DC/AC inverter having an input, an output, and a controller configured to maintain a voltage at the input within a defined voltage range. 
     
     
         14 . The DC/AC inverter of  claim 13  wherein the controller comprises a maximum power point tracker (MPPT). 
     
     
         15 . The DC/AC inverter of  claim 14  wherein the controller is configured to maintain the voltage at the input within the defined voltage range when the controller runs the MPPT. 
     
     
         16 . The DC/AC inverter of  claim 13  wherein the controller does not include a MPPT. 
     
     
         17 . The DC/AC inverter of  claim 13  wherein the inverter is a grid-tie inverter.
