1. Introduction
The Kemot Prosinus 3500 is an advanced emergency power supply system designed to protect selected electrical devices from power outages. This unit functions as a pure sine wave inverter, a battery charger, and an uninterruptible power supply (UPS). It ensures continuous operation of critical equipment by converting DC power from an external battery into stable 230V AC power.
Key features of the Kemot Prosinus 3500 include:
- Pure Sine Wave Output: Provides clean and stable AC power, suitable for sensitive electronics.
- Automatic Voltage Regulation: Maintains a consistent output voltage.
- External Battery Charging: Capable of recharging connected external batteries.
- Comprehensive Protection: Includes safeguards against overload, short-circuit, and incorrect voltage levels.

4. Setup and Installation
Follow these steps for proper installation of your Kemot Prosinus 3500:
- Battery Selection: The Kemot Prosinus 3500 (Model URZ3430) requires a 48V DC external battery system. For optimal performance, select a battery with sufficient capacity. A general guideline is that a 100W load consumes approximately 10A from the battery. Calculate your total load to determine the required battery capacity.
- Battery Connection: Connect the external 48V DC battery bank to the designated battery terminals on the rear panel. Ensure correct polarity: connect the positive (+) terminal of the battery to the positive (+) terminal of the inverter, and the negative (-) terminal of the battery to the negative (-) terminal of the inverter. Secure all connections tightly.
- Mains Power Connection: Connect the AC input of the inverter to a standard 230V AC wall outlet using a suitable power cord.
- Load Connection: Plug your electrical appliances into the AC output sockets on the rear panel of the inverter. Ensure the total power consumption of connected devices does not exceed the inverter's rated output (3500 VA / 2400 W).
- Initial Power On: After all connections are secure, switch the inverter ON using the front panel switch. Observe the display for operational status.
5. Operating Modes
The Kemot Prosinus 3500 operates in three primary modes:
- Emergency Power Supply Mode (UPS Mode): In this mode, the unit continuously monitors the mains power. If mains power is present, it passes the AC power to the connected loads and simultaneously recharges the external battery. In the event of a power failure, the inverter automatically switches to battery power, converting 48V DC from the battery to 230V AC to maintain power to your devices.
- Charger Mode: When mains power is available, the unit can operate solely as a battery charger, replenishing the external battery without providing AC output to loads (if the inverter function is switched off).
- Inverter Mode: When mains power is not connected or the unit is operating purely from battery, it converts 48V DC from the external battery into 230V AC for connected appliances.
This inverter also features constant phase detection, which is crucial for appliances sensitive to phase, such as certain gas furnaces. The phase is maintained at a fixed position, regardless of whether the unit is powered by the grid or the battery.

6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your Kemot Prosinus 3500.
- Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Ensure the ventilation openings are free from dust and debris to prevent overheating. Do not use liquid cleaners.
- Battery Inspection: Regularly inspect battery terminals for corrosion and ensure connections are tight. Check the battery's charge level and overall condition according to the battery manufacturer's guidelines.
- Environment: Ensure the installation environment remains dry, cool, and well-ventilated.
- Cable Check: Periodically check all power cables and battery cables for any signs of damage or wear. Replace damaged cables immediately.
7. Troubleshooting
If you encounter issues with your Kemot Prosinus 3500, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output from inverter | Inverter is OFF; Battery discharged; Overload; Short circuit; Faulty connection. | Turn ON the inverter; Recharge or replace battery; Reduce load; Check for short circuits; Verify all connections. |
| Battery not charging | Mains power not connected; Mains power failure; Charger current switch set incorrectly; Faulty battery. | Connect mains power; Check mains supply; Ensure charger current switch (if present) is set correctly; Test or replace battery. |
| Overload alarm | Connected load exceeds inverter capacity. | Disconnect some appliances to reduce the load. |
| Unit overheating | Blocked ventilation; Excessive ambient temperature; Prolonged high load. | Clear ventilation openings; Ensure adequate airflow; Operate in a cooler environment; Reduce load. |
If the problem persists after attempting these solutions, please contact customer support.
