A complete off-grid solar system — two paralleled 6,500W split-phase inverters, 20.48kWh of LiFePO₄ battery storage, and fourteen 415W monocrystalline panels.
Introducing the Solar Energy Kit, a comprehensive solution designed for off-grid home systems. This kit includes 14 units of 415W solar panels, 4 sets of 5.12KWH server rack batteries, 2 units of 6500W solar inverters, and two sets of solar cables, providing you with everything you need for a seamless setup.
With an average of 4 hours of sunlight per day, the solar array can generate approximately 25KW of power daily. This robust system is capable of running essential appliances such as air conditioners, well pumps, refrigerators, TVs, workshops, and offices, offering you unparalleled convenience and reliability.
Moreover, the system is highly adaptable, accommodating up to 6 identical inverters that can be paralleled in single-phase (120VAC), split-phase (240VAC), or three-phase (208V), ensuring flexibility to meet your specific needs.
For those requiring additional power, the system is expandable, allowing you to easily integrate more batteries and solar panels. Experience the freedom of off-grid living and embrace the adventures it brings with the Solar Energy Kit.
Two 6,500W inverters paralleled, with double the combined power available briefly for motor starts and other high-draw moments.
Runs standard household circuits and larger 240V appliances from the same system.
Each inverter has two MPPT trackers, supporting up to 10,000W of solar input per unit at 99.9% tracking efficiency.
Parallel up to 6 identical inverters in single-phase, split-phase, or three-phase configurations.
Add more batteries and solar panels in the future as your energy needs grow.
Meets recognized North American safety standards for solar inverter equipment.
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.
