Why Choose a 4000 Watt Off Grid Solar Panel System?
Longterm warranty and aftersales service: Xindun offers comprehensive warranty coverage, including 2-3 years for off grid solar inverter, 5 years for lithium battery, 1 year for lead-acid battery, and up to 25 years for solar panel. With years of consistent market feedback, we are confident in the quality of our products. If quality issues arise, customers can enjoy free or low cost repair support, minimizing ongoing maintenance burdens.
Strict factory inspection: Before delivery, all equipment undergoes multiple quality checks, including overload testing, input voltage and current testing, circuit verification, and safety assessments, to ensure stable and safe operation. We also employ internationally recognized thirdparty certification agencies for testing, and our products have passed multiple international standards.
Intelligent monitoring and communication: RS485 communication is used between the lithium battery and solar inverter for efficient connection. The inverter also supports RS485, WiFi, and GPRS communication with apps and computers, allowing customers to monitor operating status in real time and quickly identify and resolve potential issues.
Technology and qualification advantages: Xindunholds 15 utility model patents, 10 software patents, and 5 design patents, and has obtained numerous authoritative certifications, including CE, IEC, TUV, TLC, ISO, and MCS, ensuring ourproducts’ international competitiveness in terms of technological innovation and reliability.
Energy savings and return on investment: A 4,000watt solar panel system with battery storage can help users save approximately 60% on electricity costs in areas with abundant electricity. In areas with limited electricity, the system can generate approximately 16 kWh of electricity with 5 hours of sunshine, fully covering daily electricity needs and achieving “zero electricity bills.” Furthermore, Xinton’s 4,000 watt solar system offers users high return, helping to reduce costs and improve electricity convenience.
Flexible energy storage and charging options: 4000 watt solar panels can be paired with lithium battery, lead-acid battery, or other energy storage battery to meet continuous power supply needs day and night. The 4000 watt off grid solar panel system supports multiple charging methods: grid power, utility generators, and solar power, providing users with a more flexible and reliable energy solution.
