Sine Wave Inverter – Household

Powered by Lento

The Sine Wave Inverter – Household from Lento is built to deliver smooth, reliable, and home-friendly power backup. Designed to replicate grid-quality electricity, it ensures safe performance for sensitive appliances like refrigerators, LED TVs, laptops, fans, and kitchen equipment. Its pure sine wave output reduces noise, prevents flickering, and increases appliance lifespan, making it ideal for households that need uninterrupted comfort during power outages.

Equipped with advanced control technology, the inverter offers improved efficiency, stable voltage regulation, and faster response to load changes. It supports a wide range of battery types—including tubular, SMF, and GEL—allowing users to choose the best fit for their power needs. With user-friendly indicators, multiple safety protections, and a durable build, this domestic inverter provides dependable backup for everyday use.
