Hebei Mutian Solar Energy Technology Development Co., Ltd. is one of the most reliable manufacturers and suppliers of 1-10kw off-grid rooftop solar system in China, also supports customized service. Welcome to buy advanced 1-10kw off-grid rooftop solar system in stock from our factory.
Products Description
1. Solar Panels (PV Modules)
The solar panel installations will use high efficiency (over 21% conversion efficiency) monocrystalline or polycrystalline solar panels with anti-PID technology. Each panel will be subjected to 100% dual full EL-testing to guarantee zero defects. Every solar panel is backed by a 25 year power output warranty.
2. Pure Sine Wave Inverter
Our high efficiency inverter (up to 99.6% efficiency) converts the DC power generated by your solar panels and/or batteries into clean and stable AC power. The output of our inverter is pure sine wave and can be used with all types of standard household appliances, including sensitive electronic devices such as computers, televisions, and medical equipment. Our inverter includes an internal controller.
3. Battery Bank
You can choose from two options for battery storage; lithium-ion batteries (have a longer lifespan and charge faster) or lead acid gel batteries (less expensive to store). Lithium-ion options will come with 2x the lifespan and a 30% decrease in the charge time compared to traditional lead-acid batteries. Your battery bank will store any excess solar energy generated, so you will have power to utilize 24 hours a day regardless of whether it is night or the solar panels are generating less energy due to lack of sunlight.
4. Mounting Structure
We have custom rooftop mounting structures manufactured out of either aluminum or carbon steel. These structures were engineered to withstand all weather and ground conditions. They have an adjustable angle design, which allows for optimal orientation of the solar panels to achieve maximum use of the sun's rays throughout the year.

Product Features & Competitive Advantages
1. Advanced MPPT Controller Technology
A Maximum Power Point Tracking (MPPT) controller built into our system provides maximum energy production from the solar array by tracking its power level continuously and adjusting for variations in the level of light during the course of the day. The use of an MPPT controller results in up to 30% greater energy collection efficiency than would be found in a traditional pulse width modulation or PWM controller, giving you maximum benefit from all sunlight received by the system.
2. Pure Sine Wave Output
The system provides pure sinusoidal AC output, which is suitable for precision equipment and all types of conventional electrical loads. Unlike modified sine wave inverters, pure sine wave output ensures smooth operation of sensitive electronics, extends the lifespan of your appliances, and eliminates harmful electrical noise.
3. Dual-Core MCU Architecture
Stable control is achieved through a dual-core MCU architecture, supporting flexible switching among three modes: mains power mode, energy-saving mode, and battery mode, to meet diverse power consumption scenarios.
4. Comprehensive Protection Mechanisms
The system is equipped with multiple protection features to ensure safe and reliable operation:
Battery overcharge protection
High/low voltage automatic cut-off
Overload protection
Short-circuit protection
Temperature anomaly protection
5. Visual Intelligent Monitoring
The LCD screen displays operating parameters in real time, with clear and intuitive status indicators. Smart app monitoring is also available for remote access to real-time system data.
6. Modular & Scalable Design
The system features a modular design, allowing households to start small and expand capacity over time as energy needs grow (up to 10kW or more for entire households).
About us
As solar experts, and having performed over 50,000 deployments across 76 countries, our engineers will customize every 1-10kW off-grid rooftop solar system for:
• Spatial Limitations - Low-profile mounting brackets are suitable for tile or pitched roofs (with a slope as low as 15°); for coastal residences, integrated modules and corrosion-resistant, IP68-rated enclosures should be considered.
• Usage patterns: Peak load management for kitchen appliances (3kW induction stoves), electric vehicle charging (1.8kW dedicated circuit), and well pumps. (3HP capability)
• Future-proofing: Modular expansion from 1kW to 10kW via plug-and-play stacking batteries.
Frequently Asked Questions
Q1: How many solar watts do I need for my home?
A: Your daily energy usage dictates the size of your system. A 1kW system can provide basic light and charge your phone; a 3-5kW system can provide the primary power needs of a small home; a system of 8-10kW can supply enough power for most of the electrical use of a home, including air conditioning units and large appliances.
Q2: What is the difference between off-grid and grid-tied systems?
A: Off-grid systems are completely independent and utilize batteries for energy storage. Grid-tied systems are connected to the utility company, do not require batteries.
Q3: How long do the batteries last?
A: Depending on how you use and maintain them, lithium-ion batteries will last 5-10 years. Lead-acid gel batteries generally last 3-5 years.
Q4: Can I expand the system later?
A: Yes! The system features a modular design that allows you to start small and expand capacity over time.
Q5: What happens on cloudy days or at night?
A: The batteries that make up your battery bank supply stored energy from the sun during days that are sunny, and maintain a continuous flow of energy to your system during days with limited to no sun and through the nighttime hours. Your battery bank must be sized based on your maximum consumption (peak demand) during your lowest production period of the year (3-5 consecutive cloudy days during the winter).
Q6: Is professional installation required?
A: While your system will be installed merely by connecting all "plug and play" components, we recommend that a professional install your system to ensure optimal performance, safety, and warranty protection.
Q7: What is the lifespan of the solar panels?
A: All of our solar panel products come with a 25-year power output guarantee, and will usually last 25-30 years with very little degradation (loss in power output).
Q8: Does the system work in cold climates?
A: Yes. The system has been tested and proven effective in various climatic conditions, including severe cold seasons with photovoltaic power consumption rates of up to 90.5%.
