The EG4 12kPV Complete Hybrid Solar Kit is a versatile and efficient energy solution designed for homeowners seeking reliable hybrid power with battery backup. Combining the powerful EG4 12kPV hybrid inverter with a 5.8kW solar array and 20.4kWh server rack battery options, this system delivers dependable energy production, storage, and seamless grid interaction.

This kit is ideal for both grid-tied and off-grid applications, offering flexibility, scalability, and high-performance components. With multiple battery brands to choose from, users can tailor the system to their specific needs while maintaining long-term reliability and efficiency.

EG4 12kPV Complete Hybrid Solar Kit Features

Powerful Hybrid Inverter Technology - 8000W continuous output with 12000W PV input capacity allows for strong solar production and efficient energy management between solar, battery, and grid.
20.4kWh Battery Storage Options - Includes multiple high-quality LiFePO4 server rack batteries from trusted brands like EG4, SunGold, Rich Solar, RUiXU, and SOK.
Efficient 5.8kW Solar Array - Built with 14 × 415W Mono Black PERC panels, delivering solid daily production with excellent efficiency and durability.
Closed-Loop & Open-Loop Compatibility - Supports both closed-loop communication (EG4 LL-S) for optimized performance and open-loop batteries for flexible integration.
Expandable Energy System - Easily add more batteries or panels to increase storage capacity and solar production as energy needs grow.
Complete Installation Kit - Includes essential wiring, breakers, fuses, and mounting hardware for a streamlined setup.

EG4 12kPV Complete Hybrid Solar Kit Applications

Hybrid Home Energy Systems (Grid-Tied with Battery Backup) - Perfect for homeowners who want to stay connected to the grid while storing excess solar energy for nighttime use or outages. Maximizes energy independence while maintaining utility backup.
Partial or Full Off-Grid Setups - Ideal for cabins, rural homes, or properties without reliable utility access. Provides consistent, self-sustaining power using solar and battery storage.
Backup Power for Outages - Keeps essential appliances like refrigerators, lights, and communication devices running during power failures. Seamless transition ensures uninterrupted power when the grid goes down.

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!

Roger V.

Totally Off Grid.

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.

Jeff S.

Great Product! Fast Shipping

We added 2 more batteries to our current set up. Pleased with the customer service from Off-Grid Source! Will be back!
