Sun Gold Power 18kW Off Grid Solar Kit 48V 120/240V

Sun Gold Power Off Grid Solar Kit (Up to 18kW, 48V, 120/240V Split Phase)

This complete off grid solar power kit is built for homes, cabins, and light commercial setups that need real 120/240V power without a utility connection. It combines a split-phase inverter platform, LiFePO4 battery storage, 415W monocrystalline solar panels, and the core mounting, cabling, and protection components to build a clean, expandable system.

Choose Your Inverter Power: 12kW, 15kW, or 18kW

Inverter power is the biggie because it decides what you can run at the same time. This kit gives you inverter options so you can match the system to your load list today and still scale the rest of the system later.

• Inverter options: 12,000W, 15,000W, or 18,000W
• DC input voltage: 48V
• AC output voltage: 120V and 240V split-phase

415W Monocrystalline Solar Panels for Daily Production

The solar array is the daily engine that recharges the battery bank. With 415W panels and multiple panel count options, you can size the kit around your available space and how quickly you want the batteries to recover after overnight use.

• Solar panel type: 415W monocrystalline
• Solar panel quantity options: 12 panels or 20 panels

LiFePO4 Battery Storage with Cabinet Options

Battery capacity is what keeps the house comfortable after the sun goes down. This kit uses 51.2V 100Ah LiFePO4 batteries and supports multiple battery counts, with an enclosed cabinet sized to match.

• Battery type: lithium iron phosphate (LiFePO4)
• Battery per unit: 100Ah, 51.2V (5.12kWh each)
• Battery quantity options: 5 batteries (25.6kWh) or 6 batteries (30.72kWh)
• Enclosed battery cabinet capacity: 5 batteries or 6 batteries

Dual 100A MPPT Charge Controllers

Charge control matters for daily harvest and battery health. This kit includes two MPPT solar charge controllers rated at 100A each for efficient charging across changing sunlight conditions.

• MPPT solar charge controllers: 2 units, 100A each

Included Cables, Mounts, and Electrical Protection

This kit includes the components that prevent last-minute parts chasing and make the system easier to protect and service.

• Solar extension cables: 50 ft, 2 sets
• Battery to charge controller cables: 2 sets
• Mounting brackets: Z-brackets (12 sets or 20 sets depending on panel count)
• DC breaker rating: 400A
• PV breaker rating options: 25A or 50A

Why This Kit Makes Sense

This kit is built for people who want off grid power that feels usable, not fragile. You get split-phase 120/240V output for real household loads, a 48V platform that supports serious storage, and modular options so you can size inverter power, solar input, and battery capacity to your actual needs. If you want a system you can build now and expand later without starting over, this is a strong foundation.
