Hybrid PV solar off grid on grid tie energy storage inverter welder 48v 3kw 5kw 3000watts 5000watt with dual mppt controller

1 When the mains power is normal and the current solar power generation is bigger than the load power, solar power will feed the load completely and the surplus solar power will feed the battery and transmit to the grid.

2 When mains supply is normal and the solar power is smaller than the load power, the insufficient part is supplemented by the mains supply; The solar and the mains supply feed the load together.

3 When mains supply is abnormal, the inverter changes to independent invert mode. When the solar power is bigger than the load power, the solar power will feed the load completely, and the surplus part will charge the battery. When the solar 

power is smaller than the load power, the insufficient part is supplemented by the battery; the batteries and the solar feed the load together.

4 When solar has no generating power, the mains supply will charge and store energy to the battery through the inverter.

5 When mains supply is abnormal and there is no solar, batteries will feed the load.

1 When the mains power is normal and the current solar power generation is bigger than the load power, solar power will feed the load completely and the surplus solar power will feed the battery and transmit to the grid.

2 When the solar power is smaller than the load power, the insufficient part is supplemented by the battery. The solar and the battery will feed the load together.

3 When solar power runs out or very little and the battery is placed to below 48 voltage, the discharge power of the battery will be linearly reduced. The insufficient part will be supplemented by mains supply. And when it reaches the low-voltage protection of the battery, the load will be completely fed by the mains supply .

4 When mains supply is abnormal, the inverter will work in the independent invert mode. The solar power will feed the load. And if the solar power is insufficient, it is supplemented by the battery.

Note: under the BATT mode, if there is no solar, mains supply won’t charge the battery.

This mode is suitable for the areas which have peak and valley electricity price. According to the electricity price in different periods, the corresponding time can be set to charge and discharge from the grid.

1 When the electricity price is low, mains supply charges the batteries;

2 When the electricity price is high, the batteries feed the loads.

A: Are your inverters pure sine wave output?

Q: A Yes, All are true pure sine wave.

A: What kind of output you can do?

Q: Normally we produce inverter with 110V 115V 120V 220V 230V 240V, 50/60Hz self-adaption. If you have special requirements, please tell us for engineer consulting.

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

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

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

Q: 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.

A: What appliances your inverters can load?

Q: Our inverter can be used in household, Office, agricultural appliances and other inductive load such as refrigerator, air conditioner, water pump, etc.

A: Can you print our company logo on inverters, nameplates and packaging?

Q: Yes, we accept OEM orders.

A: How to choose a right inverter?

Q: Tell us your demand, then our sales will recommend a suitable inverter to you.

A: How to solve the technical problem?

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

A: Do I Need A Power Inverter?

Q: Actually, no. This is the only component of a solar energy system that is not absolutely required. However, if you don't use one, you will not have 220 or 230 volts AC and will have use battery power alone. This might be acceptable in a small RV or cabin, but most people want to use normal AC appliances.

A: What's The Difference Between 12, 24, And 48 Volt Inverters?

Q: This refers to the input voltage from the battery bank. The main consideration is that at higher voltages the current is less so that you can use smaller wires between your solar panel array and your battery bank. Of course, when you decide on a system voltage, the Solar Panels, Inverter, and Battery Bank all need to use the same voltage.

A: What to do if the product is broken? 

Q: If any product is faulty, you can send the picture or video to us, we sill study it and supply the spare parts of PCB board free for after sale service.
