Sol-Ark 12kW and Fortress Power 16.2kWh Battery Storage Kit
Adding storage with your PV system can be simple. Whether you have an existing grid-tie system or are planning a new project, Sol-Ark and Fortress offer a combined solution that will help you keep the lights on and your home office running during utility interruptions. "Closed-loop" communication and streamlined installation make integrating solar with storage now easier than ever.
Use with or without solar panels as a backup for your critical loads or to offset high TOU utility rates with peak load shaving. Rapid shutdown compatible APSmart devices easily integrate with new solar roof installations with UL 1741 Rule 21 compliance for a complete solar and storage solution that truly is an all-in-one compatible solution.

Sol-Ark’s 12K pumps out power just like the grid, allowing you to power 120V/ 240V and 208V appliances
- Grid-Tied, Hybrid, Off-Grid
Manages power from Solar, Battery, Grid, Load, and Generator simultaneously
Sol-Ark is expandable from 5 to 52 (16.5 kW) solar panels and 0-32 batteries. Per 12K unit.
- 10-Year Standard Warranty
No need for additional warranties. The 12K comes standard 10-year warranty right out of the box.
Helpful Hint with Sol-Ark hybrid inverters: Unlike most string inverters - Sol-Ark hybrid inverter solution will not have a complete power loss for a series string of modules if one of the panels goes bad (stops producing) *** so as long the total voltage of the remaining panel meets or exceeds the min MPPT voltage range of 150VDC.
