SunGold Power | Off-Grid Solar Kit | 24kW 48VDC 120/240VAC | 61.44kWh–64.28kWh Lithium Battery | 31 × 590W Solar Panels | FR-24K60CP / FR-24K64PM
This is a large 24,000W off-grid solar kit built for homes, farms, workshops, remote properties, and other locations with demanding power needs. The system combines two 12,000W 48V inverters, 31 × 590W bifacial N-type solar panels, and either 61.44kWh or 64.28kWh of LiFePO₄ battery storage.
The 31-panel array provides 18,290W (18.29kW) of rated solar capacity. At around 4 to 5 peak sun hours, that represents roughly 73 to 91kWh of theoretical panel output before system and environmental losses. Actual daily production varies with location, season, weather, panel orientation, temperature, shading, and bifacial rear-side gain.
The two FR12K-B inverters provide 24,000W of combined continuous output and support 120/240V split-phase power, making the system suitable for both standard 120V appliances and compatible 240V equipment.
Two versions, one powerful system. The FR-24K60CP uses twelve CoreX 5 Pro 5.12kWh server-rack batteries for 61.44kWh total storage. The FR-24K64PM uses four PowerMax 314 outdoor batteries for approximately 64.28kWh total storage. The inverter and solar array remain the same—the main difference is how the battery storage is installed and managed.

Installations needing outdoor-rated battery storage |
Choose FR-24K60CP if:
You prefer a server-rack battery system, have a suitable indoor battery location, and want twelve smaller battery modules that can be organized together.
Choose FR-24K64PM if:
You want fewer, larger-capacity batteries and an IP65 outdoor-rated enclosure, particularly where installing a large indoor server-rack bank is less practical.

Before You Order
Confirm Your Available Solar Space
Thirty-one large-format 590W modules require considerable installation space. Confirm the roof or ground-mount area is sufficiently large and receives adequate sunlight before ordering.
Plan the Battery Location
The two versions require different battery installations. The FR-24K60CP uses twelve indoor server-rack batteries, while the FR-24K64PM uses four IP65 outdoor-rated PowerMax batteries.
Have the Electrical Design Reviewed
A 24kW 48V battery system carries very high DC current. Battery interconnection, busbars, overcurrent protection, disconnects, conductor sizing, grounding, and inverter connections should be engineered for the final installation rather than assumed from a generic diagram.
Check Your Largest Starting Loads
Motors, pumps, compressors, air conditioners, and other equipment can require considerably more power during startup than during normal operation. Check both running wattage and starting/surge requirements.
Plan Your Solar Strings Carefully
Each FR12K-B provides two MPPT inputs, with a 125–425V MPPT operating range and 500V maximum PV open-circuit voltage. String configuration must remain within voltage and current limits across expected temperatures.
Professional Installation Is Recommended
Because this system combines high-voltage PV, a large 48V lithium battery bank, and 120/240V AC output, installation should be performed by appropriately qualified personnel following manufacturer instructions and applicable electrical requirements.

Frequently-Asked Questions
What is the difference between FR-24K60CP and FR-24K64PM?
The main difference is the battery system. The FR-24K60CP includes 12 × CoreX 5 Pro server-rack batteries totaling 61.44kWh, while the FR-24K64PM includes 4 × PowerMax 314 outdoor batteries totaling approximately 64.28kWh. Both versions use the same two 12kW inverters and 31 × 590W solar panels.
How much solar power does this kit have?
The kit includes 31 × 590W panels, providing 18,290W or 18.29kW of rated front-side solar capacity.
How much energy can the solar array generate each day?
At 4 to 5 peak sun hours, 18.29kW of rated panels represents approximately 73 to 91kWh of theoretical panel output before losses. Actual production can be lower or higher depending on location, weather, temperature, shading, orientation, system losses, and bifacial rear-side contribution.
Can this system provide the full 24,000W?
The kit contains two 12,000W inverters, giving it 24,000W of combined rated inverter capacity when configured appropriately. Whether a particular installation can sustain that output depends on battery configuration, cabling, busbars, protection equipment, operating conditions, and system design.
Can it power 240V appliances?
Yes. The FR12K-B supports 120/240V split-phase output, allowing properly wired installations to operate compatible 240V equipment.
Can I run a generator with this system?
Yes. The inverter platform supports generator integration, providing another source of power or battery charging when solar production is insufficient.
Can I add more panels later?
Potentially, yes, but additional panels must remain within the inverter's PV voltage, current, and maximum input-power limits. Solar expansion should be designed around the existing string configuration rather than simply adding panels in parallel.
Can I add more batteries later?
Both battery platforms support expansion within their respective manufacturer limits. Additional batteries must be compatible with the existing battery type, communication system, wiring, protection equipment, and system design.
Are the batteries suitable for outdoor installation?
The PowerMax 314 used with FR-24K64PM is IP65-rated for outdoor applications. The CoreX 5 Pro server-rack batteries used with FR-24K60CP should be installed according to their specified indoor environmental requirements.
Which battery option should I choose?
The FR-24K60CP is suited to installations where there is a dedicated indoor location for server-rack batteries. The FR-24K64PM is better suited to layouts that benefit from fewer, larger outdoor-rated battery enclosures. The choice mainly depends on installation space and battery placement rather than inverter or solar performance.
