Sol-Ark Hybrid Inverters

Sol-Ark Hybrid Inverters — True Off-Grid, On-Grid, and Backup Power

True Off-Grid Capability

Unlike most "hybrid" inverters that still require a grid reference to operate, the Sol-Ark 12K and 15K are true off-grid inverters. They can start up and power a home from a completely dead grid, running 100% on solar and battery. This makes them ideal for remote cabins, homesteads, emergency backup systems, and any installation where grid reliability is uncertain. The split-phase 120/240V output delivers power to standard North American appliances, pumps, and HVAC systems without the need for additional transformers.

Generator Input for Extended Backup

The Sol-Ark 12K features dual AC inputs, allowing simultaneous connection to the grid and a backup generator. When battery state of charge drops below a configurable threshold, the inverter automatically starts the generator, charges the batteries, and powers the home — all without interrupting AC loads. The generator auto-start feature works with any 2-wire or 3-wire start generator, and the programmable quiet hours ensure your generator only runs when necessary. For off-grid installations, this capability extends autonomy from days to weeks during prolonged cloudy periods.

Universal Battery Compatibility

Sol-Ark inverters are battery agnostic, supporting a wide range of lithium-ion and lead-acid battery chemistries. Certified compatibility includes the SOK, EG4, Fortress Power, LG Chem, and BYD battery systems, with native CAN and RS-485 communication for accurate state-of-charge reporting and BMS integration. The inverter's programmable battery profiles allow custom settings for any 48V battery bank, giving installers and DIY enthusiasts maximum flexibility in component selection.

12kW Output — Power for Every Load

With a continuous 12,000W output and 24,000W surge capacity, the Sol-Ark 12K can handle the most demanding residential loads. Air conditioners, well pumps, electric dryers, and even small EV chargers run simultaneously without the inverter breaking a sweat. The 120A passthrough capability means the inverter can pass grid or generator power directly to loads without conversion losses, improving overall system efficiency. The EMP-hardened design and military-grade surge protection protect against electromagnetic pulses and lightning strikes.

10-Year Warranty & US-Based Support

Sol-Ark stands behind every inverter with a 10-year standard warranty — one of the longest in the industry for hybrid inverters. Because the company is headquartered in Texas, all technical support, warranty claims, and engineering consultation are handled in the United States by English-speaking engineers who understand North American electrical codes and installation practices. This is a significant advantage over overseas manufacturers whose support can be limited by language barriers and time zone differences.
