SOL IA-S4 Series Off Grid Solar Inverter & Support the Parallel Operation of 9 Units

In commercial scenarios such as shops and small production workshops, electricity costs often constitute a significant part of operating expenses. The Kaimin S4 off-grid solar inverter provides enterprises with an efficient energy optimization solution.

Based on a rated output power of 3.5kW, this device supports the parallel operation of 9 units, which can not only meet the power demand of daily loads but also adapt to the power upgrade requirements for future capacity expansion. No additional core equipment replacement is required.

Its built-in MPPT intelligent tracking technology increases the solar energy conversion efficiency by more than 20% compared to traditional inverters. During the day, power consumption can mainly rely on photovoltaic power supply, significantly reducing the consumption of grid power.

In terms of battery compatibility, the Kaimin S4 is compatible with both lead-acid batteries and lithium-ion batteries. Lead-acid batteries can control the initial investment cost, while lithium-ion batteries are suitable for long-term power supply requirements in commercial scenarios, achieving a balance between cost and performance.

Additionally, the 220V standard sine wave voltage output by this device is controlled within the industrial-grade error range, enabling it to safely drive commercial loads such as cash registers and production machinery. Combined with the BMS communication system, it can also monitor the battery status and power generation parameters in real time, achieving fault warning and status visualization, ensuring the continuity of power supply for commercial operations.

For enterprises, the Kaimin S4 inverter is one of the core devices for implementing green energy transformation and reducing operating costs.
