FAQ
Q1: Can this 3 phase 48V inverter handle high inrush currents from motors?
A: Yes. Our inverters are designed with a high surge capacity (typically 2-3 times the rated power for several seconds) to reliably start inductive loads like motors, pumps, and compressors.
Q2: Is it compatible with lithium-ion (LiFePO4) batteries?
A: Absolutely. The inverter's wide DC input voltage range and configurable parameters make it ideal for use with 48V LiFePO4 battery banks. Optional communication interfaces allow seamless integration with a BMS for optimal performance and safety.
Q3: What is the difference between an off-grid and a hybrid 3 phase inverter?
A: Our standard off-grid model supplies power solely from the batteries. A hybrid model (available as an option) includes additional circuitry to connect to the AC grid or a generator, allowing for battery charging from multiple sources and selling excess solar power back to the grid.
Q4: Do you provide technical drawings and installation guides?
A: Yes. Complete installation manuals, wiring diagrams, dimensional drawings, and communication protocol documents are available for download from our support portal for all system integrators.
Q5: What is the typical lead time and warranty?
A: Standard models are typically available within 2-3 weeks. We offer a comprehensive 5-year warranty on the product, reflecting our confidence in its quality and durability for industrial applications.
