Sun Gold Power Off Grid Solar Kit 4000W 12V 120/240V

Sun Gold Power 4000W 12V Off Grid Solar Kit (120/240V Split Phase, 1200W Solar, LiFePO4 Storage)

This off grid solar kit is built for RVs, cabins, and small shops that need dependable power away from the grid. It combines solar panels for generation, a 12V inverter for AC power, lithium battery storage, and a 100A MPPT charge controller to support daily off grid living and weekend getaways.

If you want a compact 12V system that still supports 120V and 240V split phase output, this kit is a strong choice for powering real world loads with a cleaner, quieter solar plus battery setup.

What This Kit Is Designed to Do

Use the solar panels to generate energy during daylight, store it in the LiFePO4 batteries, then run your AC loads through the inverter whenever you need power. This kit is designed to support mobile and remote power needs where reliability matters and expansion is part of the plan.

4000W Inverter With 120V and 240V Split Phase Output

At the center of the system is a 4000W inverter designed for a 12V battery platform. It provides split phase 120V/240V AC output, which can be important for certain equipment and wiring layouts in cabins, shops, and property builds.

• Inverter output: 4000W
• Battery input: 12V DC
• AC output: 120V / 240V split phase

LiFePO4 Battery Storage With Bluetooth Monitoring

This kit includes lithium iron phosphate storage built for frequent cycling and dependable performance. Bluetooth monitoring makes it easier to keep tabs on battery status so you can manage loads with confidence.

• Batteries: 2 × 12V 200Ah LiFePO4 batteries
• Bluetooth enabled for battery monitoring

1200W Solar Array for Daily Charging

The solar array includes six monocrystalline panels designed to keep the battery bank charging and support consistent daily energy production.

• Solar panels: 6 × 200W monocrystalline
• Total solar power: 1200W

Estimated production can reach about 5.4kWh per day with roughly 4.5 peak sun hours, depending on location, season, temperature, and panel placement.

100A MPPT Charge Controller for Efficient Solar Harvest

The included MPPT charge controller helps maximize charging efficiency so you get more usable energy from the solar array, especially when sunlight conditions change throughout the day.

• Solar charge controller: 100A MPPT

Expandable System Design

This kit supports expansion with additional panels or batteries, making it a smart starting point if your power needs are expected to grow over time. That flexibility matters for RV upgrades, cabin improvements, and shop builds that add tools or larger loads later.

Included Cabling and Mounting Hardware

To help simplify the install, the kit includes key mounting and cable components that are often overlooked when building a system from scratch.

• Solar extension cables: 1 set, 50 ft (inverter PV input)
• Battery to controller cable: 1 set
• Mounting hardware: 6 sets of Z-brackets

What’s Included

• 1 × 4000W inverter (12V input, 120V/240V split phase output)
• 6 × 200W monocrystalline solar panels (1200W total)
• 2 × 12V 200Ah LiFePO4 batteries with Bluetooth
• 1 × 100A MPPT solar charge controller
• 1 set of 50 ft PV extension cables (inverter PV input)
• 1 battery to controller cable set
• 6 sets of Z-brackets

Best For

• RVs and mobile off grid setups that want solar plus lithium storage
• Cabins needing dependable 120V power with 120/240V split phase support
• Small shops and remote workspaces that need reliable AC power
• Buyers who want an expandable kit instead of a fixed, limited system

Why This Kit Makes Sense

This kit balances the essentials: a strong inverter, practical lithium storage, a 1200W solar array, and MPPT charge control. It is a solid foundation for off grid power where you want a complete package, clear upgrade paths, and a system designed for real use, not just emergency charging.
