Its solar input range is 12-52V, and the charging power reaches 300W, supporting both grid and solar dual charging modes to meet the flexible electricity needs of low-load scenarios such as TV, fan and light bulbs.

· Cola 2000: The power is increased to 1050W, with a capacity of 2kWh, supporting 50Hz/60Hz output, which can cover medium-load devices in households or small shops (such as refrigerators, TVs, etc.). Its solar charging power reaches 550W, which can quickly replenish electricity. In practical applications, it can power a large refrigerator for 10 hours, showing strong practicality.

· Cola 3600/3600 Plus: Designed for commercial scenarios such as vendors and also for home use, with a maximum power of 2200W and a capacity of 3.6kWh. The solar input range is expanded to 60-400V, and the charging power reaches 3000W, which can support the continuous operation of high-frequency and high-power devices, such as small refrigerated cabinets, juice machines, microwave ovens, induction cookers, etc.

2. Solar Panels: Efficient and Clean Energy Input

· SP320: With a maximum power of 320W, it adopts a 64-cell design and an open-circuit voltage of 32.95V. It can efficiently capture solar energy under Standard Test Conditions (STC) and is suitable for small energy storage systems.

、

· SP580: With a maximum power of 580W, it is applicable to Cola 2000 and above models. In 3.6kWh applications, multiple panels can be connected in series, balancing power and installation convenience.

3. Batteries and Inverters: The "Core Heart" of Energy Storage Systems

· Cola 15K Battery: With a capacity of 15kWh, it adopts a 1P16S connection , a battery voltage of 51.2V, and a maximum output current of 150A, providing stable energy storage support for high-power scenarios.

· IV 10.2K Inverter: With a rated power of 10.2KW , the conversion efficiency is up to 94%. It accepts 48V voltage level battery input, and the output voltage is stable at 220-240Vac±5%, adapting to various energy storage scenarios to ensure efficient and stable energy conversion.

II. Technological Breakthroughs: Redefining the Core Advantages of Home Energy Storage

Colasolar's product competitiveness stems from a number of core technological innovations, from topological structure to material application, all reflecting the ultimate pursuit of "efficiency, convenience, and safety".

1. Single-Cell Topology and Integrated Design: Simplifying Structure and Improving Reliability

· Single-Cell Technology: It adopts 3.2VDC single cell directly adapted to 220VAC output. Compared with the traditional 24/48VDC multi-level conversion scheme, it reduces energy loss links and lowers circuit complexity.

· Integrated Integration: The inverter, MPPT (Maximum Power Point Tracking) controller, and battery are integrated into one, realizing "plug-and-play" without professional installation, which greatly reduces the user's threshold. This design not only reduces the risk of equipment connection failure but also makes the system volume more compact, saving household installation space.

2. Gallium Nitride (GaN) Technology: Dual Optimization of Performance and Cost

As a representative of the third-generation semiconductor materials, the application of GaN in Colasolar's products has become a key technological highlight, and its performance advantages are far superior to traditional silicon (Si) and gallium arsenide (GaAs):

· High Efficiency and Low Consumption: GaN has a band gap of 3.4eV, a breakdown field strength of 3.3MV/cm, and an electron mobility of 2000cm²/V·s, which increases the conversion efficiency of the energy storage system to 92% (traditional silicon-based schemes are about 86%), significantly reducing energy loss.

· Miniaturization and Low Cost: The high voltage tolerance of GaN materials allows for more compact circuit design, reducing the system volume by 30%. At the same time, its non-toxic characteristics reduce environmental treatment costs, and the overall scheme cost is 30% lower than that of traditional technologies, achieving a balance between "high performance and economy".

3. Intelligent Protection and Adaptive Design: Coping with Complex Electricity Environments

· Wide Voltage Compatibility: For areas with frequent grid fluctuations (such as Nigeria), the product is designed with a wide AC input range of 150-264V to ensure stable operation even when the voltage is unstable.

· Triple Protection Mechanism: Through three-level protection of software, hardware, and fuses, combined with real-time communication between the integrated BMS (Battery Management System) and the inverter, multiple protections such as overload, over-temperature, and over-charging are realized to avoid equipment damage and improve use safety.

III. Conclusion: Driving the Popularization of Home Energy Storage with Technology

Colasolar has built a differentiated competitive advantage through the dual paths of "product scenarization + technical solidification". Its products not only cover the diverse electricity needs from households to small businesses but also solve the pain points of traditional energy storage systems such as "complex installation, low efficiency, and high cost" through technological innovations such as single-cell topology and GaN material application.

For users, the value of Colasolar lies in "simplifying energy acquisition with technology" — no professional knowledge is required for installation and use, no need to worry about the impact of grid fluctuations, and at the same time, enjoying the low cost and environmental benefits brought by clean energy. Against the backdrop of global energy transformation, Colasolar is promoting the popularization of renewable energy in household scenarios with "easy home energy storage" as the core, truly realizing the brand vision of "Switch on Happiness!".
