Here is a gallery of Nickel Iron batteries that I have personally installed. All batteries are installed in a ventilated battery box, these photos were taken before the final box is installed. Let me know if you have any questions.
400Ah 24Volt battery with 3.2kW inverter and charge controller to power a hacienda near Hatch, New Mexico.
Massive 1000Ah 48V NiFe battery powers a monolithic concrete Dome in Aspen Park, CO.
This 600Ah 24V powers an entire farm near the Comanche National Grassland, south east Colorado. The Trace inverter is the true workhorse here!
Off the grid 700Ah 48 Volt battery, pre-wired power panel with dual 80Amp MPPT charge controllers.
