Enhancements in the SUN-30K-SG02HP3-EU-AM3: A Step Up from the SG01HP3-EU-BM3 Model

The upgraded SUN-30K-SG02HP3-EU-AM3 model presents several improvements compared to the previous version, the SUN-30K-SG01HP3-EU-BM3. Here’s a detailed comparison:

1. Appearance and Port Layout:

SG02HP3-EU-AM3: The upgraded version features an optimized layout of the ports. While the ports and functional interfaces remain largely unchanged in terms of functionality, the arrangement has been improved for better accessibility and organization.

SG01HP3-EU-BM3: This version has a more traditional port layout, which may not be as streamlined as the newer model.

2. Battery Power Terminals:
SG02HP3-EU-AM3: The newer model features only one set of battery power terminals, which simplifies installation, but it lacks a pressure-relief valve.

SG01HP3-EU-BM3: The previous version includes more comprehensive battery power terminals and a pressure-relief valve, offering more options for complex setups.

3. Internal Structure and PCB Design:

SG02HP3-EU-AM3: All PCBs in the SG02 model have been completely redesigned, which enhances the overall performance, reliability, and efficiency of the inverter.

SG01HP3-EU-BM3: The SG01 version utilizes the baseline PCB set, which may not offer the same level of optimization and performance enhancements seen in the upgraded version.

4. Weight and Size:
SG02HP3-EU-AM3: The newer model is significantly smaller, lighter, and easier to install, weighing 46 kg (excluding connectors and brackets) and with dimensions of 448 × 688 × 270 mm.

SG01HP3-EU-BM3: The older model is larger and heavier, weighing 80 kg with dimensions of 527 × 894 × 294 mm, which could make installation more cumbersome.

5. PV Input and String Configurations:

SG02HP3-EU-AM3: The PV input configuration remains the same, with 36 A for each input and a similar string layout (3/2/2/2).

SG01HP3-EU-BM3: The previous version also supports 36 A per input and the same string configuration. The improvements in the newer version don't focus on this aspect but rather on other internal components.

6. Size and Efficiency:
SG02HP3-EU-AM3: The reduced size and weight of the SG02 model make it an ideal choice for users looking for easier installation and space-saving solutions.

SG01HP3-EU-BM3: The larger, heavier design could be less suitable for certain installations where space is a constraint.

Conclusion:
The SG02HP3-EU-AM3 model is a significant upgrade over the SG01HP3-EU-BM3, focusing on enhanced portability, improved PCB design, and a more user-friendly port layout. While both models offer similar PV input and string configurations, the SG02’s optimized design, lighter weight, and redesigned internals make it a better option for most modern installations requiring more efficient and manageable solar power systems.
