Product Overview & System Integration

The Hemao 5kW off-grid solar power system is an engineered solution for autonomous residential electricity, remote telecom stations, and independent power networks. This system integrates high-efficiency photovoltaic panels, a pure sine wave off-grid inverter, and a 10kWh lithium iron phosphate (LiFePO4) energy storage bank. Designed for maximum compatibility, the system interfaces directly with existing residential distribution panels and diesel backup generators.

As a primary China factory and OEM supplier, Xiamen Hemao Industry offers deep customization, including custom PCB engineering, structural mounting adapter design, and specific enclosure modifications to meet regional electrical codes.

Material & Technical Specifications

Quality Control & Global Standards

Every 5kW off-grid solar system undergoes a rigorous multi-stage testing protocol before shipment from our factory. Photovoltaic modules pass dual EL (electroluminescence) defect testing to eliminate micro-cracks. The 10kWh energy storage system undergoes a 100% full-capacity active aging test for 48 hours under maximum thermal load. Our production lines comply with global quality baselines, backed by TUV, CE, RoHS, UN38.3, and MSDS certifications, ensuring structural safety and electrical compliance for international import.

Packaging & Logistics Safety

Lithium batteries are classified as Class 9 Dangerous Goods for international transport. Hemao utilizes export-grade, heavy-duty UN-certified packaging to guarantee secure transit. The 10kWh battery units and 5kW inverters are housed in multi-layer corrugated boxes with high-density molded foam inserts, secured onto fumigated, reinforced wooden pallets. Solar panels are packed in vertical heavy-duty cartons with corner protectors, strapped with steel banding, and braced inside the shipping container to prevent shifting during maritime freight.

Typical Application Scenarios

Off-Grid Residential Power: Reliable base-load electricity for remote houses lacking stable grid infrastructure.

Remote Telecom Base Stations: Continuous DC/AC power supply for communication towers in isolated environments.

Agricultural Solar Irrigation: Distributed power for water pumping and automated farming control systems.

Commercial Island & Resort Grids: Modular energy setups reducing dependence on localized diesel generation.

FAQ

Q: Can this 10kWh LiFePO4 battery bank integrate directly with existing third-party inverters?

A: Yes. The built-in BMS protocols are pre-programmed to communicate with major global inverter brands via RS485, CAN, or RS232 interfaces. For non-standard voltage ranges, our factory engineering team provides custom firmware updates to ensure seamless voltage matching and safety parameters.

Q: How does the 10-year linear warranty protect against battery capacity degradation over time?

A: Our warranty guarantees the 10kWh battery retains at least 80% of its nominal capacity after 10 years of standard daily cycling. This performance is sustained by our selection of Tier 1 Grade A cells, which naturally resist thermal degradation and internal resistance increases.

Q: What is the exact lead time for custom OEM brand printing and custom chassis color manufacturing?

A: For standard batch orders with custom logo laser printing, the manufacturing lead time is 15 to 20 days. If your project requires custom metal enclosure stamping, mold development, or specific RAL color powder coating, the structural engineering phase adds 10 working days to the initial production schedule.
