Applications

The best applications for the Sol-Ark 18K are whole-home backup, off-grid, grid-tied, and time-of-use savings.

  • Grid-Tied Mode – Sell power back to the utility to reduce your electric bill
  • Meter Zero Mode – Zero out your electric bill without adding an additional smart meter
  • Time-Of-Use Mode – Use solar + batteries to minimize grid power usage when it’s most expensive
  • Smart Load Mode – Programmable output for high-power off-grid loads or grid interaction
  • Time-of-Use Loads – Run only when solar is optimal, using excess PV power when batteries are full
  • Off-Grid Applications – battery agnostic
  • AC Coupling – retrofits to existing grid-tied systems
  • Battery Backup – seamless, zero load shedding
