FAQ - Sofar HYD-40K-T1model
1. Can the HYD-40K-T1 operate without a battery?
Yes, it can operate as a standard on-grid UPS. Adding batteries activates the hybrid and standby functions.
2. What type of battery is compatible?
This inverter is designed for high-voltage (HV) batteries. SofarSolar maintains an official compatibility list.
3. Is it compatible with a generator?
Yes, the inverter has a dedicated port or can be configured to integrate with a generator, ensuring a continuous supply even in the event of a prolonged power cut.
4. Is it necessary to balance three-phase loads on the emergency output?
No. This is one of its strong points: the AC-Backup output supports up to 100% unbalanced load between phases, which is crucial for commercial buildings.
5. Can several inverters be connected in parallel?
Yes, the system is designed to be paralleled (up to 10 units) to create high-power plants (up to 400 kW) with storage and back-up functions.
6. How can I monitor production and consumption?
Via the SolarMAN Cloud platform (mobile application or web interface), accessible via the optional Wi-Fi logger, enabling real-time monitoring of production, consumption and battery status.
