Frequently Asked Questions (FAQ)
What core power component is used in this three-phase off-grid inverter?
The inverter utilizes an advanced IGBT module from Mitsubishi company as the main power component to ensure high efficiency, reliability, and stable performance.
What is the standard bypass transfer time, and can it be adjusted?
The standard transfer time for the AC bypass is ≤40ms for the 10KW model and ≤100ms for models between 20KW and 50KW. A customized fast transfer version of ≤4ms can also be ordered.
Does this inverter support remote monitoring and communication?
Yes, it supports multiple communication modes including RS485, Wifi, GPRS, and Ethernet utilizing the standard Modbus RTU protocol for seamless monitoring.
What safety protection features are integrated into the system?
The inverter features a comprehensive suite of built-in protections: input reverse polarity protection, input under-voltage protection, output overload protection, output short circuit protection, and over-temperature (thermal) protection.
Can I connect a solar charger or a backup generator to the system?
Yes, optional ports and integrations for both solar chargers (MPPT/PWM), AC chargers, and auxiliary generator ports are fully compatible and available to configure.
Are these inverters compatible with high-altitude environments?
The standard design supports operation up to 2000 meters above sea level without power loss. For altitudes higher than 2000m, the rated power output should be reduced accordingly.
