Frequently-Asked Questions

Is this kit truly off-grid capable?

Yes. This kit is designed to operate completely independently from the utility grid. It includes a split-phase inverter, LiFePO₄ battery storage, solar charge controllers, and all necessary solar panels, making it a full-featured off-grid system.

Can I expand the battery or solar panel capacity in the future?

Absolutely. The inverter and charge controllers support expansion. You can add more solar panels and LiFePO₄ batteries depending on your future energy needs.

How much power does this system generate per day?

Assuming 4 hours of full sunlight per day, the system can generate up to 33.2kWh daily (8.3kW x 4 hours).

What appliances can this system run?

This system can support most household loads including refrigerators, air conditioners, lights, fans, TVs, well pumps, and electric tools — simultaneously depending on consumption levels and battery state.

Is this system suitable for use with grid-tied setups?

No. This specific setup is for off-grid applications only. It does not include net-metering features or grid-tied synchronization.

Do I need professional installation?

While this kit includes most of what’s needed for setup, we recommend hiring a licensed solar installer or electrician to ensure safe and proper configuration.

How long will the batteries last?

The included LiFePO₄ batteries typically last 10+ years with up to 6000+ cycles depending on usage, depth of discharge, and maintenance.
