Max parallel capacity: 800AH (4P)
3. Solar inverter
Features:
● 3 times peak power, excellent loading capability.
● Combine inverter/solar controller/battery all in one.
● Multiple output: 2*AC output socket, 4*DC 12V, 2*USB.
● Working mode AC prior/ECO mode/Solar prior selectable.
● AC charging current 0-10A selectable.
● LVD/HVD/Charging voltage adjutable, suitable for kinds of battery
● Adding fault code to monitor real-time work situations.
● Continuous stable pure sine wave output with inbuilt AVR stabilizer.
● Digital LCD and LED for visualization of operation status of the equipment.
● Inbuilt automatic AC charger and AC mains switcher, stwitch time ≤ 4ms.
Remarks: you have many options of the inverters for your system.different inverters with different features.
4. Solar Charge Controller
Feature:
● Advanced MPPT tracking, 99% tracking efficiency. Compared with PWM, the generating efficiency increase near 20%.
● LCD display PV data and chart simulates power generation process.
● Multiple working modes to adapt different working occasion.
● Wide PV input voltage range, convenient for system configuration.
● Intelligent battery management function, extend battery life.
● 12V/24V/48V automatic recognition, users are more flexible and convenient to use.
● RS485 communication port optional.
What service we offer?
1. Design service.
Just let us know the features you want, such as the power rate, the applications you want to load, how many hours you need the system to work etc. We will design a reasonable solar power system for you.
We will make a diagram of the system and the detailed configuration.
2. Tender Services
Assist guests in preparing bid documents and technical data
3. Training service
If you a new one in the energy storage business, and you need a training, you can come our company to learn or we send technicians to help you to train your stuff.
4. Mounting service& maintenance service
We also offer mounting service and maintenance service with seasonable & affordable cost.
5. Marketing support
We give big support to the customers who agent our brand "Dking power".
we send engineers and technicians to support you if necessary.
we send certain percent extra parts of some of the products as replacements freely.
What is the minimum and max solar power system you can produce?
The minimum solar power system we produced is around 30w, such as solar street light. But normally the minimum for home use is 100w 200w 300w 500w etc.
Most of people prefer 1kw 2kw 3kw 5kw 10kw etc for home use, normally it is AC110v or 220v and 230v.
The max solar power system we produced is 30MW/50MWH.
How is your quality?
Our quality is very high,because we use very high quality materials and we make rigorous tests of the materials. And we have very strict QC system.
Do you accept customized producing?
Yes. just tell us what you want. We customized R&D and producing energy storage lithium batteries, low temperature lithium batteries, motive lithium batteries, off high way vehicle lithium batteries, solar power systems etc.
What is the lead time?
Normally 20-30 days
How you guarantee your products?
During the warranty period, if it is the product reason, we will send you replacement of the product. Some of the products we will send you new one with next shipping. Different products with different warranty terms. But before we sending, we need a picture or video to make sure it is the problem of our products.

Features of solar power system:
The use of solar energy is mainly divided into several aspects: small household solar power plants, large grid connected power plants, building integrated photovoltaic glass curtain walls, solar street lamps, wind solar complementary street lamps, wind solar complementary power supply systems, etc. The main application modes are building integration and wind solar complementary systems.
Advantage
1. Solar energy is inexhaustible. The solar radiation energy received on the earth's surface can meet 10000 times the global energy demand. As long as solar photovoltaic systems are installed in 4% of the world's deserts, the electricity generated can meet the global needs. Solar power generation is safe and reliable, and will not be impacted by energy crisis or unstable fuel market;
2. Solar energy is available everywhere and can be supplied nearby without long-distance transmission, thus avoiding the loss of long-distance transmission lines;
3. Solar energy does not use fuel and its operating cost is very low;
4. Solar power generation has no moving parts, is not easy to use and damage, and is easy to maintain, especially suitable for unattended use;
5. Solar power generation will not produce any waste, has no pollution, noise and other public hazards, has no adverse impact on the environment, and is an ideal clean energy;
6. The construction period of the solar power generation system is short, convenient and flexible, and the capacity of the solar array can be arbitrarily added or reduced according to the increase or decrease of the load to avoid waste.
Shortcoming
1. The ground application is intermittent and random, and the power generation is related to climate conditions, so there is little or no power generation at night or in rainy days;
2. The energy density is low. Under standard conditions, the solar radiation intensity received on the ground is 1000W/M ^ 2. Large size use requires a large area;
3. The price is still expensive, 3~15 times that of conventional power generation, and the initial investment is high.
