A complete off-grid solar system — 12,000W split-phase inverter, 25.6kWh of LiFePO₄ battery storage, and twelve 415W monocrystalline panels — sized for a mid-sized home or cabin.
Presenting our off-grid solar power system kit, a comprehensive solution designed to bring solar power and battery storage to any remote location. This all-inclusive kit features 12 top-of-the-line 415W solar panels, a robust 25.6kWh battery, a 12,000W solar inverter, and a complete set of solar cables and brackets.
Generating approximately 20kWh per day with just 4 hours of sunlight, this kit offers reliable energy production for your off-grid needs. Equipped with a 12kW split-phase inverter (120/240V) output, it provides ample power to operate a variety of appliances and devices, from air conditioners and well pumps to lights, refrigerators, TVs, workshops, offices, and even light commercial and industrial applications.
Moreover, this system is designed for expansion, allowing for seamless integration of additional batteries and solar panels in the future to meet growing energy demands. With our off-grid solar power system kit, enjoy sustainable energy independence wherever you are.
Rated continuous output with a 20-second surge rating triple the continuous power for motor starts and other high-draw moments.
Runs standard household circuits and larger 240V appliances from the same system.
Two external solar charge controllers included, giving room to expand well beyond the 4,980W (12×415W) of panels included here.
Monitor charge controller status and performance via Bluetooth, without needing to be on-site.
Add more batteries and solar panels in the future as your energy needs grow.
Minimal energy loss whether running on battery, solar, or passthrough grid power.
Junction box rated for full submersion protection, backed by a 25-year linear product warranty.
182mm Grade-A monocrystalline cells for a higher conversion rate per panel.

With about 4 hours of direct sunlight, the panel array produces roughly 20kWh per day — enough for air conditioners, well pumps, lights, refrigerators, TVs, workshops, offices, and light commercial or industrial applications, per the manufacturer's own description.
No — this kit pairs the inverter with two separate 100A MPPT solar charge controllers, rather than a controller built into the inverter itself.
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.
This kit includes a server rack cabinet sized for all five 100AH batteries, rather than mounting them individually.
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.
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.
