## Long description

The electro base Inver300 reserve set provides a compact backup power solution for electric heating systems. It combines a 300W inverter and a 12V, 50Ah battery to supply temporary energy to small electric heaters, control electronics or other low-power components during mains outages. The set is designed for integration with existing 12V installations and offers portable, straightforward operation for short-term heating support.
Advantages
The Inver300 set delivers up to 300 watts of AC output from a 12V battery source, enabling continued operation of smaller heating devices and control units when mains power is unavailable. Its compact battery capacity of 50Ah balances portability and runtime for brief emergency use. The combination of inverter and battery simplifies deployment and reduces the need for separate component sourcing. Installation and connection follow common 12V conventions, facilitating integration into many heating system configurations.
Suitable for
 Temporary powering of small electric heaters and fan convectors
 Backup supply for control electronics and thermostats
 Short-term emergency heating during power outages
 Portable or remote sites with 12V infrastructure
Key specifications
 Inverter output power: 300 W continuous
 Input voltage: 12 V DC
 Battery capacity: 50 Ah
 Battery nominal voltage: 12 V
 Intended use: backup for low-power heating and control circuits
 Portability: compact set suitable for temporary deployment
How to use
Connect the inverter to the 12V battery following the polarity markings on both devices and secure all terminals. Place the battery and inverter on a stable, dry surface with adequate ventilation and keep them away from heat sources. Plug the heating device or control electronics into the inverter's AC output and switch the inverter on. Monitor battery voltage and device power draw to ensure the load does not exceed the 300W continuous rating; disconnect the load before performing maintenance or when charging the battery with an external charger designed for 12V lead-acid batteries.
Usage recommendations
Use the Inver300 set for short-duration backup only; avoid continuous operation at or near the maximum rated power to prevent overheating and reduce battery life. Regularly check battery state, keep connections clean and tightened, and charge the battery after discharge using a suitable 12V charger. For higher power needs or longer autonomy, consider a larger-capacity battery or a higher-power inverter.
