❓ Frequently Asked Questions
What is the main benefit of a low-frequency toroidal transformer?
The toroidal transformer in our hybrid inverter reduces static power consumption by up to 50% compared to high-frequency designs, offering higher efficiency and better stability for heavy inductive loads.
Can this inverter work with Lithium (LiFePO4) batteries?
Yes, the system features adjustable charge currents and voltages, and specifically supports BMS communication for LiFePO4 batteries (models 2KVA to 12.5KVA).
How long does the transfer take during a power outage?
The inverter features a professional UPS design with an automatic transfer time of less than 10ms, ensuring your sensitive electronic devices remain powered without interruption.
What are the different working priority modes available?
Users can choose between Utility Priority (UTI), Solar Priority (SOL), or Battery Priority (SBU) modes to optimize energy usage based on local conditions and cost.
Does the inverter support remote monitoring?
Yes, it offers optional WiFi or GPRS plugs that allow you to monitor system parameters and status via a mobile app or PC.
What protections are built into the system?
The inverter includes comprehensive protection against overloading, short-circuits, low battery voltage, and high voltage faults to ensure long-term system reliability.
