Off Grid Solar Inverter
In the 15kw solar power system, we use three 5kw off grid inverters in parallel, the inverter offers several advantages, including an equalization charging function that helps to extend battery life and maintain optimal performance. It also features configurable grid or solar input priority, allowing users to prioritize their power sources based on availability and preference. Additionally, the inverter supports optional WiFi/GPRS remote monitoring, enabling users to monitor and control their system from a distance.
Floor Standing LifePO4 Battery
The LiFePO4 phosphate lithium batteries floor standing type have a high energy density and a lifespan of 10 years, exceeding 6000 cycles, IP20 ingress protection rate, we also have IP65 floor mounted type batteries to meet the market demands.
Aluminum Mounting Bracket
Our solar mounting structure of the 15kwh solar system offers a robust and versatile solution for 15 kilowatt solar system installations. It is designed to withstand various environmental conditions, ensuring long-term stability and durability.

In this 15kw solar system, we use 27 pieces of 550w solar panels. Other powers of the solar panels are available. Considering the total power of the system is 15kw, the power of the solar panels you choose, and the solar inverter specifications, then you will know about the number of solar panels.
The number of batteries in the 15kw solar system you need depends on the specification of the batteries and the total electricity energy you need at night or on rainy days. For example, if you need 20 KWH to use at night, and you have no connection to the utility grid, and you consider the 51.2V 200Ah battery, then the battery number would be: 20KWH/51.2V/200Ah = 2 pieces.
Sure. Installation of the 15kw solar system will increase the value of your house. It is a valuable investment for you to reduce electricity bills, make your electricity energy independently, and increase the property in the long run.
The 15 kW solar system will generate about 59.4kwh power per day considering there are 4 hours of effective sunshine in your area, suitable for 5 to 8 people in a family. It can power home appliances such as refrigerators, lights, ovens, air conditioners, electronic lights, etc.
We provide professional services for the 15 kilowatt solar system through WhatsApp/email/WeChat, assisting you with installation and answering any questions you may have. For each solar system we sell, we have photos and installation demo videos, you can find them on our Youtube channel. Our engineer will also go overseas to help you if necessary.
You can also consult local solar installers. They all offer free home solar installation consultations and cost evaluations. We suggest that you get installation quotations from at least three companies to compare prices and be sure to inquire about any discounts and preferential activities they may offer.
It depends on your installation location, your local sunlight conditions, your local feed in tariff, your usual electricity cost, the approximate value of your electricity consumption, and your total cost of the 15kw solar system fee and the installation fee.
You need to calculate the total value of electricity that the solar energy system can generate annually. Then, divide the total cost of purchasing and installing the system by this total value to figure out the payback period.
