\nFrequency variations
\nPower interruptions
\nElectrical disturbances
\n2. Generator Compatible Operation\uff1a
\nThe 3H15kVA UPS supports generator input connection.<\/p>\n

For stable operation, the recommended generator capacity should be at least 2 times the UPS
\nrated capacity\uff1a<\/strong>
\n\u00b7Remote areas
\n\u00b7Industrial sites
\n\u00b7Backup power systems<\/p>\n

3. Flexible System Configuration<\/strong>
\nThe system supports flexible configuration according to different application requirements:<\/p>\n

\u00b7Optional output isolation transforme
\n\u00b7Adjustable battery quantity: 16-20 battery units
\n\u00b7Adjustable charging current: 1-4A

\n\u00b7Automatic restart after mains recovery<\/p>\n

4. Parallel Expansion Capability<\/strong>
\nSelected models support parallel operation with up to 3 UPS units, allowing higher capacity expansion and improved system redundancy.<\/p>\n

5. Comprehensive Protection System<\/strong>
\nThe UPS integrates multiple protection functions to ensure safe and reliable operation:<\/p>\n

Protection includes:<\/p>\n

\u00b7Output overload protection
\n\u00b7Output short circuit protection
\n\u00b7Inverter over-temperature protection
\n\u00b7Battery undervoltage warning
\n\u00b7Battery overcharge protection<\/p>\n

6. Intelligent Interface and Monitoring Management<\/strong><\/p>\n

The LCD display provides real-time information including:<\/p>\n

UPS operating status
\nInput\/output parameters
\nBattery information
\nAlarm records<\/p>\n

Communication interfaces:<\/p>\n

RS232
\nRS485
\nSNMP network adapter<\/p>\n

The UPS monitoring software enables remote management through computer systems.<\/p>\n

7. High Environmental Adaptability<\/strong><\/p>\n

The internal circuit boards are installed in a fully enclosed structure and treated with conformal coating technology.<\/p>\n

This improves resistance against harsh environments such as:<\/p>\n

Dust
