Our service center repairs UPS units with capacities ranging from 1 to 10 kVA, including the LP11-1kVA, LP11-3kVA, LP11-6kVA, and LP11-10kVA models. We ensure full restoration of equipment functionality, replacement of worn components, and modernization of battery systems.
Repair Work Procedure
Repairs of the General Electric Lan Pro LP11 UPS at the service center of Total-Energo LLC are performed in accordance with standard procedures:
- Diagnostics — initial assessment of the equipment’s condition using specialized testers, analysis of logs and event systems, and verification of input/output voltage parameters and internal components.
- Preparation of a defect report listing the identified malfunctions and recommendations for their resolution.
- Supply of spare parts — if necessary, original GE components or their manufacturer-approved equivalents are ordered. We work through official supply channels.
- Device cleaning — comprehensive cleaning of dust, corrosion, soot, and contaminants that may cause overheating or short circuits.
- Repair and restoration — replacement of IGBT transistors, driver boards, mains filters, power supply circuits, interface connectors, capacitors, control and protection elements.
- Commissioning — restoration of default settings, verification of auto-start, ECO/Online mode, and battery switchover.
- Testing — prolonged load testing (using active or combined loads) to verify output voltage stability, inverter performance, and autonomous operation.
- Documentation — work completion report, recommendations for further operation, and (if necessary) warranty card.
In case of complex malfunctions, repairs are performed at the service center of Total-Energo LLC using certified diagnostic equipment and an electrical test bench for load testing.
Replacement and modernization of the battery pack
Lan Pro LP11 series UPSs use external AGM or GEL batteries. As the service life increases, there is a need for:
- Replacing worn-out batteries with new ones (including selection based on capacity and voltage);
- Checking the battery controller, restoring charge/discharge uniformity;
- Upgrading to LiFePO4 — lithium iron phosphate batteries with improved performance;
Advantages of switching to LiFePO4:
- Voltage stability even under high load;
- Lifespan 5–6 times longer than that of lead-acid batteries (up to 6,000 cycles);
- Lighter weight, reduced heat generation;
- Integration with a BMS system for protection and monitoring;
- Better suitability for facilities with high requirements for uninterruptible power supply.
Battery replacement involves recalculating the runtime and checking the UPS charger settings.
