Product Description

UL Inverter 


Sandi off grid UL inverter approved by UL1741 and CSA22.2 standard, popular for US, Canada and worldwide. It can make split phase 120/240VAC or 3 phase 120/208VAC 60hz output or custom made to your specification.It’s suitable for all kinds of AC load. With SVPWM technology it has high conversion efficiency, high instantaneous power and low losses power output pure sine wave, applying to capacitive, inductive and nonlinear mixed-load, with superior load capacity, perfect protection function: overload, short circuit, low/over battery voltage, improper operation etc, which won’t cause mechanical failures.

This Off Grid UL Inverter is very suitable for solar power systems, wind power generation systems, wind and solar hybrid generation systems.
