FAQ

Common Questions

Does this inverter have a built-in solar charge controller?

Yes — the NOVA 6548 has a built-in 120A MPPT controller, so no separate charge controller hardware is needed for this kit.

How much usable battery capacity does this system have?

15.36kWh combined from three 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.

Can I add more panels or batteries later?

Yes — the inverter supports up to 8,000W of solar input in total, above the 6,560W included, and the battery system can scale up to 30 units in parallel.

Do I need a licensed electrician to install this?

Given the scale of this system — a 6,500W inverter, a 15.36kWh battery bank, and a 6,560W solar array — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
