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.
