Traditionally, there have been two main options for solar installation designers and engineers to convert DC to AC power: string inverters or micro inverters. Both present significantly different advantages and disadvantages for installers, with installation expenses varying up to 20 percent depending on the inverter selection. Either solution had drawbacks: what one would gain in convenience, it would sacrifice in performance and maintenance and vice versa. But a new class of inverter is entering the market that combines the installation simplicity of a string inverter with the intelligence and energy harvest advantages of a micro inverter.
