Frequently-Asked Questions

Can this kit power my entire home?

It may support whole-home or essential-load backup when appropriately sized. Your simultaneous loads, appliance starting requirements, and selected battery’s discharge capability determine what can run together.

Why does the kit have 11kW of solar and a 12kW inverter?

The included panels total 11kW of rated solar capacity. The inverter provides 12kW continuous AC output at 240V and can utilize up to 18kW of PV input. These figures describe different system capabilities.

How long will the battery provide backup power?

Runtime depends on the selected battery’s usable capacity, charge level, connected loads, and system losses. The options provide approximately 14–16kWh of nominal storage.

Can this system sell excess electricity back to the grid?

The EG4 18kPV supports grid export when correctly installed and configured. Export availability depends on utility approval, interconnection requirements, and your electricity plan.

Can I expand the system later?

Yes. Compatible batteries and additional solar panels may be added within the inverter’s electrical limits and manufacturer requirements. Expansion may require additional wiring and equipment.

They Stood By Me

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!

Bruce D.

Awesome Service!

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.

Jennene A.

Real Person, Honest Service.

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.

Easy Return

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!
