Not Sure This Is The Right System?
Request a Free Solar ProposalThe SunGold Power 12kW Off-Grid Solar Kit is a complete solar energy system designed for off-grid homes, remote properties, and residential backup power applications. Combining a 12,000W pure sine wave inverter, 9.44kW of N-Type bifacial solar panels, and 30.72kWh of LiFePO4 battery storage, this kit provides a powerful solution for generating, storing, and using solar energy.
The system includes 16 × 590W bifacial solar panels to capture sunlight and a 48V battery system to store energy for nighttime use or periods of reduced solar production. Its 120/240V split-phase AC output supports compatible household appliances and electrical equipment.
Available in FR-12K30CP and FR-12K30CE configurations, the kit offers two battery options to accommodate different installation preferences and energy storage requirements.
12,000W Pure Sine Wave Inverter
The system features a 12kW off-grid solar inverter that delivers 120/240V split-phase AC power for compatible household appliances and electrical equipment. Its pure sine wave output supports a wide range of residential loads.
9.44kW N-Type Bifacial Solar Array
The kit includes 16 × 590W bifacial solar panels, providing a combined 9,440W (9.44kW) of rated solar capacity. The N-Type cell technology is designed for efficient solar energy conversion, while the bifacial design can capture additional reflected sunlight under suitable conditions.
30.72kWh LiFePO4 Battery Storage
Both configurations provide 30.72kWh of nominal lithium battery storage, allowing homeowners to store solar energy for evening use, cloudy weather, and backup power applications.
Two Battery Configuration Options
Choose between the FR-12K30CP and FR-12K30CE versions. Both provide the same nominal energy capacity but use different battery configurations and connection components.
120/240V Split-Phase Output
The inverter supports 120V and 240V AC power, making the system suitable for compatible residential electrical installations that require split-phase electricity.
Long-Lasting LiFePO4 Battery Technology
The included batteries use Lithium Iron Phosphate (LiFePO4) chemistry, known for its thermal stability, long cycle life, and suitability for residential energy storage.


Every major system component, matched and ready to wire together.

What is included in the SunGold Power 12kW Off-Grid Solar Kit?
Both configurations include one 12kW inverter, sixteen 590W solar panels, six LiFePO4 batteries, solar extension cables, a battery cable, and two PV breakers. The main difference is the battery model: CoreX 5 Pro for FR-12K30CP and CoreX 5 Elite for FR-12K30CE.
How much solar power does this kit provide?
The kit includes 16 × 590W bifacial solar panels, providing a combined rated capacity of 9,440W (9.44kW) under standard test conditions.
What is the total battery capacity?
Both configurations provide 30.72kWh of nominal battery storage through six 51.2V 100Ah LiFePO4 batteries.
What is the difference between FR-12K30CP and FR-12K30CE?
The FR-12K30CP includes CoreX 5 Pro server rack batteries and six battery brackets. The FR-12K30CE includes CoreX 5 Elite wall-mounted batteries. Both provide the same nominal storage capacity and inverter output.
Can this kit power an entire house?
The inverter provides 12,000W of rated output, supporting many compatible household appliances, including refrigerators, lighting, pumps, and certain air-conditioning equipment. Whether it can power an entire home depends on simultaneous demand, startup loads, and the electrical system design.
How much electricity can the solar panels generate per day?
With five peak sun hours, the 9.44kW array has a theoretical production of 47.2kWh per day before losses. Using an illustrative 80% system-efficiency assumption gives approximately 37.8kWh per day. Actual generation varies with weather, shading, orientation, temperature, and system design.
Can I use this system without utility electricity?
Yes. The kit is designed for off-grid applications, using solar generation and battery storage to supply compatible electrical loads. A properly designed installation may also incorporate supported generator charging.
Does the inverter support remote monitoring?
Yes. SunGold Power advertises Wi-Fi remote monitoring and automatic generator-start capability for the included 12kW inverter system.
Do I need additional installation components?
Possibly. Roof or ground mounting equipment, grounding components, electrical protection, conduit, and other installation materials may be needed. These should not be assumed included unless listed in the selected package.
Can I install the system myself?
Professional installation is strongly recommended. The system involves high-voltage solar wiring, high-current battery connections, and residential 120/240V electrical circuits.

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.
