You are correct that our earlier documentation mentioned automatic switching between single-phase and three-phase charging based on available solar energy and user-defined profiles. However, this functionality has since been redesigned.
During the development phase, we actively experimented with dynamic transitions to single-phase charging across all charging modes. However, based on extensive feedback from the majority of our clients, we found that this feature did not meet user expectations in real-world solar charging scenarios.
The main issue arises when solar generation hovers just below or above the minimum current threshold of 6 A, as defined by the IEC 61851 standard. In these cases, the charger would frequently attempt to switch charge types and phases—particularly when using single-phase charging—leading to unstable behavior and frequent interruptions in the charging process.
To ensure a more stable and user-friendly experience, we decided to remove automatic phase switching from the solar-based charging modes. The charger now operates in 3-phase mode by default, maintaining a robust and reliable charging process even with fluctuating solar input. Automatic switching between charge types is only retained in regular (non-solar) charging modes where it offers tangible benefits without compromising stability.
We’re in the process of updating our documentation to reflect these improvements, and we appreciate your understanding as we evolve the product based on real-world use and user feedback.
