EMP-Hardened Hybrid/Off-Grid Solar Inverter · 48V
Battery agnostic, EMP-hardened, and built for fleet management — the Sol-Ark 15K EMP delivers 15,000W of continuous real power with 19,500W of max allowed PV input, backed by a 10-year warranty and 7-day-a-week live engineering support.
The Sol-Ark inverter comes with everything you need to install it. Nicely packaged for added efficiency.
With Sol-Ark's remote access features and app you are never out of touch to quickly repair or adjust any system without being on site.
Sol-Ark inverters also do not have expensive battery restrictions like other solar inverters do, and can be used with a wide variety of 48V battery chemistries, from lead to lithium.
Comes with our award-winning iron clad warranty and our 7-day-a-week live engineering support to assist you in all your needs.
