■ DC to AC 3 Phase Frequency Converter Details
■ DC to AC 3 Phase Frequency Converter Wiring Diagram
We offer 2 optional working modes for 3 phase converter (transfer time≤4ms):
1. Home or Industry Backup System:
When AC grid power is available, inverter charges battery, at the same time, AC grid power bypass through inverter to home/industrial appliances, such as freezer, water pump, electric drill. When AC grid power is off, it will automatic transfer switch to battery power and convert DC to AC power.
2. Wind or Solar Power system:
Convert DC to AC power. When battery power is lacking, it will automatic transfer to grid power for powering continuously.

Q1: Are you a factory?
A: Yes, we are the top 10 power supply manufacturers in China, with over 7000 square meters production area. We focus on dc to ac converters, solar charge controllers, solar generators and solar power system solution. We cooperate with some famous brands all over the world, can provide customized production or add your logo on products.
Q2: What is the price of dc to 3 phase ac converter?
A: Tell me your requirements, such as power, voltage, charging current, quantity, and whether there are other functional requirements. We will give you the most favorable ex factory price. DC to 3 phase AC converter factory direct sales, no middlemen earn price difference.
Q3: What type of converters do you produce?
A: We produce various types of converters: pure sine wave converters, off-grid converters, on/off grid converters, solar hybrid converters, single phase converters, 3 phase converters, low frequency converters, high frequency converters, etc. Don’t know which type of converter to choose? Contact XINDUN now!
Q4: What's the difference between pure sine wave converter and modified sine wave converter?
A: Pure sine wave output converter is just as good as the public power grid, even better. Low repaired rate, long lifespan, without harmonic pollution, enviromental-friendly and appliances protected.
Modified sine wave output converter has a negative impact on appliances and can't load inductive load, such as air contition, refrigerator and etc. Certain motor control circuits don't like the modified wave.
Q5: What's the difference between solar converter and hybrid converter?
A: converter is design to turn DC (Direct Current) into AC (Alternating Current). Both solar converter and hybrid converter are widely used in PV solar energy into electric energy. Hybrid converter contains the function of a solar converter, also adds a built-in solar charge controller. Also it can be a combination of off grid and grid tie converter in one machine with same description as you called hybrid converter.
Q6: How to solve the dc to 3 phase ac converter technical problem?
A: We will provide market and product training services, 24 hours after-service consultancy just for you and to make your problem to solveeasily.
