Yes, pure sine wave inverters can be paralleled, but only if they are designed for it. Always use certified models with parallel function, follow setup instructions carefully, and ensure your system components are compatible.
[pdf] This article presents the first kW-Class, 3-phase GaN-based inverter. Hard-switched at 100-kHz PWM, its heart is a 6-in-1 power module with 600-V GaN power HEMTs, achieving a new efficiency of 98.5%, a more than 2% improvement.
