2000w Inverter-Controller Integrated Machine
2000w inverter introduce
The 2000W inverter is the core component of the solar energy system. Its core function is to convert the direct current (DC) output by the solar panel or battery into 220V/110V alternating current (AC),
directly driving daily appliances (such as rice cookers, lighting equipment) or industrial equipment (such as water pumps, motors).
This conversion process solves the problem that direct current cannot directly supply power to AC loads, making solar power generation truly “once generated, ready for use”.
Key technical advantages
MPPT technology: By real-time tracking of the optimal operating voltage of the solar panel, it ensures that the maximum power can still be output under different lighting conditions (such as cloudy days, cloudy days), and the power generation efficiency is improved by 15%-30%.
Intelligent power management:
Mains power complementation: Automatically switch to mains power supply when solar energy is insufficient (switching time ≤10ms) to ensure the continuous operation of key equipment (such as medical instruments, servers).
Battery optimization: Supports 3-level intelligent charging (constant current → constant voltage → floating charge), extends battery life, and can repair aging batteries.
Working principle:
DC boost and inversion
The low-voltage DC output of the solar panel (such as 12V/24V) is boosted to high-voltage DC (such as 300-400V) by a high-frequency PWM controller.
The high-voltage DC is converted into high-frequency AC through a full-bridge inverter circuit, and then outputs stable industrial frequency AC (50Hz/60Hz) through a filter.
Intelligent protection and heat dissipation
Multi-level protection: input overvoltage/undervoltage protection (such as shutdown when the voltage is lower than 10V or higher than 15.5V), overload protection (shutdown within 20 seconds when the load exceeds 150%), overheating protection (start the fan when the temperature is ≥60℃, and shut down when ≥70℃).
Temperature control and heat dissipation: The cooling fan is intelligently controlled by the CPU, and automatically stops when the load is low, reducing energy consumption (no-load current <1.8A).
