Hybrid design for full energy independence

The Sol-Ark 15K-LV integrates solar PV, battery storage, and generator inputs, allowing users to achieve complete off-grid capability or grid-tied resilience. Its transformerless DC design maximizes conversion efficiency while enabling seamless switchover between power sources in as little as 5 milliseconds—keeping critical loads running without interruption.

Smart battery management and compatibility

Engineered for flexibility, the inverter supports both lithium and lead-acid batteries within a 43–63V operating range and up to 275A charge/discharge current. Built-in BMS communication via CANBus and RS485 ensures precise control and long-term battery performance, while an integrated 3-stage charging controller with equalization maximizes battery lifespan.

Built-in protection and compliance

The 15K-LV meets UL1741SB, IEEE 1547a, CA Rule 21, and HECO Rule 14H standards. It includes PV rapid shutdown, arc-fault, ground fault, surge, and reverse polarity protection—all integrated for safer operation and simpler installation. The inverter’s IP65/NEMA 3R housing ensures reliability in harsh climates with quiet operation under 30 dB.

Flexible installation and expandability

With three MPPTs and support for up to 19,500W of solar input, the Limitless 15K-LV adapts easily to complex array layouts. Its scalable design allows up to 12 units to operate in parallel for expanded system capacity, ideal for large residences or multi-building properties.

High efficiency, low noise operation

Delivering 97.5% peak efficiency and 96.5% CEC efficiency, the inverter ensures exceptional energy conversion while maintaining whisper-quiet performance below 30 dB. With low standby consumption (90W) and an intelligent cooling system, it optimizes performance and longevity under all load conditions.
