1. Battery number and capacity should be configured according to the rated voltage of the solar power system or inverter;

2. We offer 3 optional working modes (transfer time≤4ms):

1) AC priority mode (d0)
. When the mains power is normal (in line with the inverter power input voltage range), on the one hand, the mains power charges the battery (if built-in solar controller, the mains power and solar energy charge the battery at the same time); on the other hand, only the mains power supplies power to the load (the load does not consume solar and battery energy);

. When the mains power is abnormal (the mains power is beyond the working range of the inverter or the mains power is interrupted), the inverter will switch to the battery mode, and the battery will supply power to the load (if built-in solar controller, when the solar power is greater than the load power, the load will be completely supplied by the solar energy, and the excess energy will charge the battery; when the solar energy is less than the load power, the insufficient part will be supplemented by the battery. The load is supplied by solar energy and battery together).

2) PV priority mode (d1)
. When the solar is normal (in line with the solar input voltage range of the inverter), if the solar power is greater than the power of the load, the load is completely powered by solar, and the solar excess enengy charges the battery, when the solar power is less than the power of the load, the insufficient part is supplemented by the battery, and the solar and the battery supply power to the load together. If the battery is low volage due to the load, then the inverter will turn to the AC mode for power supply, and the solar will only charge the battery;
. When the solar is abormal (the solar volage exceeds the working range of the inverter or the solar is interrupted, the inverter will directly switch to the AC mode for power supply, and the mains power will charge the battery.

3) Battery priority mode (d2)
. When the inverter has no low-voltage battery alarm, even if the mains power input is normal, the inverter will switch to the battery mode, and the battery will supply power to the load. When the solar power is greater than the load power, the solar power will supply power to the load completely. and the excess enengy will charge the battery. When the solar power is less than the load power, the insufficient part will be supplemented by the battery, and the solar and battery will supply power to the load together;
. When the battery is low voltage (i.e. the voltage of a conventional single battery is 11vdc) and the mains power input is normal, the inverter will switch to the AC mode and the mains power will supply power to the load completely, while the solar energy will charge the battery but the mains power does not charge the battery.

Xindun has obtained ISO international quality management system certification, and has obtained dozens of software copyright certificates and patent certificates. Inverters products have passed CE,TLC,IEC certification and have test reports.

Q1: Are you a factory?
A: Yes, we are ISO9001:2015 manufacturing with qualifications of TUV, CE, ROHS & CCC. main products including inverter, solar controller and solar energy system solution.

Q2: Are you inverter pure sine wave output?
A: Yes, all of our inverter are pure sine wave output.

Q3: What kind of output you can do?
A: Normally, we produce inverter with 110v/ 50Hz, 120V/ 60Hz, 220v/ 50Hz, 230v/ 50Hz, 240V/50Hz.
If you have special requirements, pls tell us for engineer consulting.

Q4: What appliances your inverters can load?
A4: Our inverter can load household appliances other inductive load such as refrigerator, air condition, water pump, etc.

Q5: How long is your factory?
It's over 13 years. at the beginning our factory focused on domestic market.
From 2012, we set up our oversea sales department.

Q6: What' s the difference between low frequency and high frequency inverter?

A: Low frequency inverter has various protections, strong ability to adapt to the environment. more reliable, with voltage regulation.

Q7: What's the difference between pure sine wave inverter and modified sine wave inverter?

A: Pure sine wave output inverter 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 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.

Q8: How to solve the technical problem?

A: 24 hours after-service consultancy just for you and to make your problem to solveeasily.

Q9: What to do if the product is broken?

A: Usually we do standard exporting package and insurance in case of broken. If any product is faulty, please send us the picture or video, we will study it and supply the spare parts of PCB board free for after sale service.
