Sol-Ark 18K Hybrid Solar Inverter – All in One
Zero load shedding with 200A passthrough — no subpanel required!
The 18K is perfect for whole-home backup. Features include parallel stacking, grid sell, meter zero, time of use, smart load, AC coupling, & peak shaving.
All-In-One
The Sol-Ark 18K Outdoor Case is a pre-wired system with minimal additional hardware, your install stays simple and cost-effective.
Battery Agnostic
Sol-Ark inverters do not have expensive battery restrictions like other solar inverters do. The 18K works with a wide variety of 48V battery chemistries, from lead to lithium.
Highly Accelerated Life Testing
Proven to last well beyond the standard 10-year warranty.
Engineered, Serviced, And Tested In The USA

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
