How much energy can this system generate daily?
Under ideal conditions with approximately 4–5 peak sun hours per day, the 13.28kW solar array can generate approximately 53–66kWh of energy daily. Actual production will vary depending on location, weather conditions, shading, and installation angle.
How long will the 25.6kWh battery bank last?
Runtime depends on energy consumption. Essential household loads can typically be powered for a full day or longer, while the large solar array helps replenish battery capacity quickly during daylight hours.
Can this system power an entire home?
Yes. The 16,000W inverter system is designed to support substantial residential electrical loads, including HVAC systems, well pumps, refrigerators, freezers, lighting, electronics, and other household appliances.
Is the system expandable?
Yes. Additional battery storage and compatible system components can be added to accommodate future energy requirements and growing power demands.
Is LiFePO4 battery technology safe?
Yes. Lithium Iron Phosphate batteries are among the safest lithium battery chemistries available, offering excellent thermal stability, long cycle life, and minimal maintenance requirements.
Is this system suitable for full-time off-grid living?
Absolutely. With over 13kW of solar generation capacity and 25.6kWh of battery storage, this kit is specifically designed for serious off-grid applications and whole-home energy independence.

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.
Ray B.
I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!
Roger V.
I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
