Common Questions

Does this inverter have built-in solar charge controllers?

No — this kit pairs the inverter with two separate 100A MPPT solar charge controllers, rather than a controller built into the inverter itself.

What's the actual usable battery capacity?

25.6kWh combined from five 5.12kWh CoreX 5 Pro battery packs in the included server rack cabinet, each with real-time SOC/SOH monitoring via Bluetooth or WiFi.

Are the batteries stored in a rack or individually?

This kit includes a server rack cabinet sized for all five 100AH batteries, rather than mounting them individually.

Can I add more solar panels later?

Yes — this system is easily expandable, letting you add more batteries and solar panels as your energy needs grow, per the manufacturer's own product description.

Do I need a licensed electrician to install this?

Given the scale of this system — a 12,000W inverter, dual charge controllers, and a 25.6kWh battery bank — installation should be handled by a qualified, licensed electrician familiar with your local code.

Solar panels backed by a 25-year linear product warranty plus a 10-year workmanship warranty. Inverter is covered by a 1-year warranty.

Exceptionally Powerful

The true star of the show, however, is the massive 30.72KWh battery bank. This isn't just a battery; it's a powerhouse. We can easily go through multiple cloudy days and still have an abundance of stored power. Waking up to a battery still at 60% after a full night of running everything is a feeling I can't describe. It provides an incredible peace of mind

Very pleased!

For the price it's a great kit, I added 4 additional batteries and always have plenty of backup power. The manuals and information on how to set things up are lacking in my opinion, but tech support was great and helped with all my problems. My only big complaint is the inverter output terminal block size,it's not big enough to get the proper size conductors in. You'll either need to cut down your wire (not ideal), run smaller wire (also not ideal), or use pin terminal type ferrule. Half the connections are not used on this inverter anyway, so a larger terminal block would have been easy to fit.
