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.

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.
The eFlex 5.4 kWh 48 Volt Lithium Iron Battery by Fortress Power is a safe, scalable solution for any project’s energy storage needs.
