Frequently Asked Questions
What is the advantage of using a Mitsubishi IGBT in this inverter?
The Mitsubishi Insulated Gate Bipolar Transistor (IGBT) provides superior power component performance. It ensures high thermal efficiency, faster switching speeds, and robust reliability under heavy load conditions compared to standard power components.
Which communication modes are supported?
The inverter supports RS485, Wifi, GPRS, and Ethernet protocols. It runs on the Modbus RTU protocol, allowing for easy remote data monitoring and management.
Can I customize the bypass transfer time?
Yes. The standard bypass transfer time is ≤40ms for the 10KW model and ≤100ms for larger models. However, we offer customized options with a transfer time of ≤4ms to protect highly sensitive electrical equipment.
Does the inverter come equipped with built-in protections?
Yes, the inverter features comprehensive built-in protections, including DC input reverse polarity protection, under-voltage protection, AC output overload protection, short-circuit protection, and thermal/over-temperature protection.
Are solar and AC chargers integrated or optional?
Both solar charge controllers and AC battery chargers are offered as optional, modular integrations. You can choose to add them depending on your specific system requirements and setup configuration.
How does the altitude affect the inverter's rated power?
The inverter operates at 100% capacity up to an altitude of 2000m. For installation sites higher than 2000m, the rated power output must be derated due to thinner air and reduced cooling efficiency.
