Where It Fits
Common Questions
Why are there two inverters instead of one?
Two 6,500W NOVA 6548 inverters are paralleled to reach the system’s combined 13,000W rating. Up to 6 identical units can be paralleled for even larger installations.
Can I choose a different panel array size?
Yes — this same battery-and-inverter platform is also available with 38× 335W panels (12.7kW), 32× 400W panels (12.8kW), or with no panels included at all.
How much usable battery capacity does this system have?
20.48kWh combined from four 5,120Wh ALPHA 5 PRO batteries, each rated for 7,000 deep cycles and expandable up to 15 units in parallel.
Does the inverter support solar, grid, and generator input?
Yes — each NOVA 6548 inverter accepts solar, battery, utility mains, and generator power, with configurable charging priority via the LCD control panel.
Do I need a licensed electrician to install this?
Given the scale of this system — two paralleled 6,500W inverters, a 20.48kWh battery bank, and a 12.3kW solar array — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
