## Summary description

KEMOT PROsinus-800 is a power inverter delivering 800 VA (500 W) continuous output, converting 12 V DC to 230 V AC with a pure sine wave output. Designed for powering sensitive electronics, appliances and tools from a 12 V battery in vehicles, boats or off-grid setups. Provides stable voltage, safer operation for electronics and compatibility with loads requiring clean AC power.

## Long description

KEMOT PROsinus-800 is a 12V to 230V pure sine wave power inverter that provides 800 VA (500 W) continuous output. It converts a 12 V DC battery supply into a stable 230 V AC output suitable for sensitive electronics, appliances and small tools. The inverter can be used as an uninterruptible power source for heating boiler feed pumps and fans during supply voltage failures when paired with a 12 V lead‑acid battery (Pb) with capacities between 18 and 120 Ah; reserve time depends on the battery capacity.
Advantages
The pure sine wave output ensures clean, low‑distortion AC power compatible with sensitive devices and motors. Compact design for vehicle, boat or stationary off‑grid use. Built‑in protections guard against overload, short circuit and low battery voltage. Direct 12 V input allows straightforward connection to lead‑acid batteries in backup configurations.
Suitable for
Backup power for heating boiler feed pumps and fans during mains failure
Powering sensitive electronics and household appliances from a 12 V battery
Use in vehicles, boats or small off‑grid installations
Key specifications
Continuous output: 800 VA (500 W)
Input voltage: 12 V DC
Output voltage: 230 V AC, pure sine wave
Recommended battery type: 12 V lead‑acid (Pb), 18–120 Ah
Protections: overload, short circuit, low battery voltage
How to use
Connect the inverter to a suitable 12 V lead‑acid battery following polarity markings, then connect the AC load to the inverter output. Ensure the battery capacity matches the desired backup time; larger capacity batteries provide longer reserve time. Observe the inverter’s continuous power rating when selecting loads and avoid operating loads that exceed the specified output.
Usage recommendations
Use a well‑maintained lead‑acid battery within the recommended 18–120 Ah range and check battery state regularly. For long backup durations choose higher capacity batteries and ensure proper ventilation around the inverter and battery during operation.
