Sol-Ark Home & Commercial Energy Storage Systems

Sol-Ark

Sol-Ark Hybrid Inverters & Battery Systems

Sol-Ark builds some of the most capable all-in-one hybrid inverters available, trusted for whole-home backup, off-grid living, and commercial energy storage. Krato Power carries the full Sol-Ark lineup, from the compact 5K up to the 60K commercial unit, plus L3-HV battery banks, with the system-design help to match it all to your loads.

One unit runs everything

A Sol-Ark hybrid inverter manages solar, battery, grid, and generator in a single pre-wired unit, with high surge capacity to start demanding loads like well pumps and air conditioning. EMP-hardened options are available.

Choose your Sol-Ark

  • Sol-Ark 5K: compact all-in-one for smaller off-grid and backup setups.
  • Sol-Ark 8K: mid-size hybrid, available with an EMP hardening kit.
  • Sol-Ark 12K (Essentials, Limitless, 12K-2P): whole-home hybrid for smaller homes and tighter budgets.
  • Sol-Ark 15K / 15K-2P: the flagship whole-home hybrid and the most popular model.
  • Sol-Ark 18K-2P: more capacity for larger homes and heavier loads.
  • Sol-Ark 30K & 60K (three-phase): for large residential and light-commercial systems.
  • L3-HV battery banks (40 to 60 kWh, indoor and outdoor): scalable storage matched to your inverter.
