Additional Documentation
Common Questions
Why are there two inverters instead of one?
Two 6,500W BluePower SP6548 inverters are paralleled to reach the system’s combined 13,000W rating. Up to 6 identical units can be paralleled in single-phase, split-phase, or three-phase configurations.
Does this inverter have built-in solar charge controllers?
Yes — each BluePower SP6548 has two built-in MPPT trackers, so no separate charge controllers are needed for this kit.
What’s the actual usable battery capacity?
20.48kWh combined from four 5.12kWh powerwall batteries, each rated for at least 7,000 cycles to 80% depth of discharge.
Can I add more solar panels later?
Yes — you have the flexibility to add more batteries and solar panels to meet your energy requirements, per the manufacturer’s own product description.
Do I need a licensed electrician to install this?
Given the scale of this system — two paralleled 6,500W inverters and a 20.48kWh battery bank — installation should be handled by a qualified, licensed electrician familiar with your local code.
