Ideal for small devices, chargers and audio/video equipment requiring clean sinusoidal power.

## Long description

KEMOT PROsinus-500 is a 500VA power inverter that converts 12V DC to 230V AC with a pure sine wave output. It is intended to supply heating boiler feed pumps and fans during mains supply interruptions; backup duration depends on the connected battery capacity. The inverter is compatible with lead‑acid (Pb) batteries rated 12V and between 18–120Ah.
Advantages
The pure sine output delivers a stable, low‑distortion AC voltage suitable for sensitive electronics and inductive loads such as pumps and fans. With a compact 500VA rating it supports small household devices and charging equipment while offering straightforward connection to a 12V Pb battery bank. The unit provides automatic DC to AC conversion and reliable backup power during supply failures.
Suitable for
Heating boiler feed pumps
Boiler circulation fans
Small household appliances within 500VA
Chargers and audio/video equipment requiring pure sine power
