SEEDSUN

1. Pure sine wave output.
2. Low frequency toroidal transformer lower loss.
3. Brand new wide LCD screen, clearly and precisely shows working data.
4. Three -stage charging: Constant current , constant voltage, float charge.

5. Three types working modes; Battery type selectable.

6. Added fault code query function, easy to monitor  the operation in real time.

7. Supports RS232 or RS485 communication port.

8. Built in MPPT/PMW controller.

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

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

01 Grid priority mode: When the grid and battery are connected to the invertor, grid will supply power to the loads directly after voltage being stabilized and charge batteries via invertor. When the grid is cut off, the battery will automatically continue to supply power via invertor. 
02 Energy saving mode: If the power of the connected AC loads is lower than 5% of the invertor's rated power, there will be no output from the invertor. Only the chip of invertor is working. The power consumption of the invertor is only 1~6W. The LCD shows the output voltage 0. If the power of the connected loads is over 5%, within 5S the invertor will automatically convert DC to AC to supply power for the loads . The LCD shows the output voltage.
03 Battery priority mode: When the grid and battery are connected to the invertor, battery will supply power to the loads first. When battery capacity is not enough, the grid will continue to supply power automatically.

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 10 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.
