Solis Solar Inverters for Residential, Commercial & Energy Storage Systems
Grid-Tied Solar, Battery Storage & Backup Power Solutions
Solar Electric Supply stocks a wide range of Solis string inverters, engineered for professional solar installations across residential and commercial markets. With over a decade of proven North American field performance, Solis inverters combine advanced MPPT technology, superior efficiency ratings, and comprehensive safety systems to deliver reliable energy conversion for projects of every scale. From compact residential systems to large commercial installations, our Solis inverter portfolio provides the technical specifications and professional features demanded by today's solar integrators.
Advanced monitoring capabilities including string-level diagnostics and I-V curve scanning enable professional O&M optimization, while wide MPPT voltage ranges and high string current capacity ensure maximum energy harvest from modern high-power modules including bifacial technologies.
Choosing a Solis Inverter
Choose a grid-tied inverter when the system's primary job is converting solar power for an active utility service. Choose a hybrid inverter when the project also needs battery charging, backup output, or generator coordination.
Next, match the building's electrical service: use 208V low-voltage models for 120/208V three-phase systems and 480V models for 277/480V three-phase systems. Once topology and voltage are set, compare rated power and MPPT count.
