When choosing a solar energy storage system, it's essential to consider both technical parameters and supplier qualifications. Here are the key selection points:
1. Photovoltaic Panel Power Matching: Select an appropriate power level based on load requirements. For example, a 390W photovoltaic panel is suitable for small to medium-sized applications, such as monitoring equipment or home power supply. Calculations should consider local sunshine duration to ensure power generation covers daily consumption.
2. Battery Capacity and Type: Capacity (e.g., 200Ah) determines power supply duration and needs to be estimated in conjunction with load power. Prioritize lithium iron phosphate batteries due to their high safety and wide temperature adaptability. Avoid high-rate discharge batteries to prevent shortened lifespan.
3. Output Parameter Verification: The output voltage should be a standard 220V, with a frequency range of 50~60Hz to ensure compatibility with common electrical appliances. The main unit's output capacity (e.g., 10000W) must exceed the peak load to prevent overload.
4. Brand Reliability and Customization Services: Choose a qualified supplier and check if they offer custom processing services. Brands like Fuyida, based on years of engineering experience, can optimize designs for different scenarios. Evaluate company case studies, such as Yida Optoelectronics' applications in communication base stations and monitoring systems, to ensure comprehensive technical support and after-sales service.
