Can this kit power an entire off-grid home?
Yes, this kit is capable of powering most off-grid homes, depending on your energy usage. With a 10kW inverter and 20.48kWh of battery storage, it's ideal for running lights, refrigerators, appliances, well pumps, electronics, and even some air conditioning depending on daily consumption.
How many hours of sunlight are needed to fully charge the batteries?
With 10 x 550W panels (totaling 5.5kW) and assuming an average of 4 peak sun hours per day, the system can produce up to 22kWh/day—enough to fully charge the 20.48kWh battery bank under ideal conditions.
Can I expand the system later?
Yes. The inverter supports parallel operation with up to 6 units, and the battery bank is expandable as well. You can add more solar panels and batteries as needed.
Does the system work during a power outage?
Absolutely. This is a fully off-grid system, so it continues to operate during outages and does not require a grid connection to function.
Is installation included or DIY-friendly?
This kit is designed for professional installation or experienced DIYers. Wiring diagrams and manuals are provided, but we recommend hiring a licensed solar installer for safe and optimal setup.
What maintenance is required?
Very minimal. Clean your solar panels regularly and occasionally check battery connections. The LiFePO4 batteries and inverter are low-maintenance and long-lasting.

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.
