Product Features
What this model is for, what it does well, and what to confirm before it goes on a project.
Powering small surveillance and security equipment from a 12V lead-acid or lithium battery bank in solar-backed installations.
True sine wave output with THD under 3% helps sensitive electronics run smoothly instead of on a rough modified waveform.
Accepts 10–16.5 VDC input, making it a practical fit for 12V storage battery systems with normal charge and discharge swings.
Low and high battery voltage alerts and shutdowns, plus short circuit, overload, overvoltage, overtemperature and reverse polarity protection.
