How to Choose the Suitable Microinverter - AC Cable

TSUN "hand in hand" AC Cable Microinverters vs. "General Cable" Microinverters

Microinverters are increasingly favored by photovoltaic system installers for their unique safety, efficiency, and Flexibility. Most brands on the market, the core functions of each are generally similar, but differences are more apparent in power capacity, structural design, and safety standards. One significant differentiation is the AC output wiring method, where two main design approaches are prevalent: the "hand in hand" and the "Generalcable" methods. Let's examine the differences between these two approaches and how installers should choose between them.

General Cable

Each microinverter has only one AC output cable. For high-power system, each microinverter connects to a central "general cable" through its built-in AC cable and T-shaped connectors, unifying the system connection.

    ● Cost: With one less AC cable, the cost of microinverters is more advantageous.

    ● Installation Difficulty: Requires stripping the cables and then connecting them, which is cumbersome and needs professional installation.

    ● Installation Cost: Requires cable connectors, general cables, and waterproof plugs, resulting in more components.

       The complex installation is labor-intensive and incurs higher costs.

    ● Failure Rate: With more components, the system has more potential failure points. T-shaped connectors have three connection points,

       increasing the likelihood of faults.

Hand in hand AC Cable

Each microinverter has two AC output cables. For high-power system, microinverters connect using their built-in AC cables for plug &play system connections.

    ● Cost: With two AC cables, the cost of microinverters is relatively higher.

    ● Installation Difficulty: Two AC cables offer plug &play convenience, making installation much easier.

    ● Installation Cost: No additional connectors or cables are needed, resulting in lower installation costs.

    ● Failure Rate: With only two connection points for plug & play, the failure rate is lower.

    ● EMC Standards: Two AC cables present more challenges for EMC testing, which is one of the main reasons most brands opt to cancle AC cables.

TSUN pioneered the "hand in hand"AC cable microinverter in 2019 and has consistently innovated in this design direction, establishing itself as a leader in the industry. Tsun remains committed to the belief of "Making Installation Easier" and has launched various "Hand in hand" AC cable microinverter solutions, including the TSOL-MS300/350/400, TSOL-MX400/450/500, TSOL-MS600/700/800, TSOL-MX800/900/1000, and TSOL-MS1600/1800/2000 series. When choosing a suitable microinverter, installers should consider not only the individual cost of the microinverter but also factors such as installation, after-sales, and long-term performance. TSUN continues to innovate in the microinverter field and will soon release the high-power 6KW microinverter to achieve optimal cost and help more households easily access green energy. Stay tuned!
