Where It Fits
Common Questions
Why doesn’t this kit include solar panels?
It’s designed for customers who already have panels or want to select them separately. The NOVA 12K supports up to 12,000W of PV input across two MPPT trackers, so panels can be added to match your site.
How much usable battery capacity does this kit have?
61.44kWh combined from twelve 5,120Wh ALPHA 5 PRO batteries, each rated for 7,000+ deep cycles and expandable up to 30 units in parallel.
Can the batteries charge in freezing temperatures?
Each ALPHA 5 PRO has an integrated 150W heater that activates automatically below 41°F and shuts off once the battery warms past 50°F; charging locks out entirely below 32°F.
Does the inverter support generator or grid input?
Yes — the NOVA 12K accepts solar, battery, utility, and generator input, with a second input power source supported for generator compatibility.
Do I need a licensed electrician to install this?
Given the scale of this system — a 12,000W hybrid inverter and a 61.44kWh battery bank — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
