Build a DIY Off Grid Solar System With the Sun Gold Power 13KW Kit

Built for whole-home off-grid power, Sun Gold Power 13000W 48VDC 120V/240V 20.48KWH Lithium Battery 4440W Solar Panel Off-Grid Solar Kit pairs two paralleled 6500W split-phase inverters with wall-mounted PowerWall lithium batteries for dependable, space-saving energy storage.

Twelve 370W monocrystalline panels and four 100Ah 51.2V PowerWall batteries deliver 20.48kWh of storage and 13,000W of split-phase output, giving large homes, cabins, and workshops room to grow without dedicating floor space to a battery rack.

What's Included:

Specifications

  • Product Type: Off Grid Solar Kits
  • Inverter Configuration: 2 x 6500W 48V Split-Phase Inverters, Paralleled for 13,000W Total Output
  • System Voltage: 48VDC
  • AC Output: 120V/240V Split Phase
  • Solar Panels: 12 x 370W Monocrystalline Solar Panels
  • Total Solar Array Power: 4,440W
  • Battery Configuration: 4 x 100Ah 51.2V PowerWall (Wall-Mounted) LiFePO4 Batteries
  • Total Battery Capacity: 20.48kWh
  • Battery Format: Wall-Mounted PowerWall Design (Space-Saving, Not Rack-Mounted)
  • Solar Extension Cable: 2 Sets x 50 ft for Inverter PV Input
  • Mounting Hardware: 12 Sets of Mounting Z-Brackets
  • DC Breaker: 2 x 200A
  • PV Breaker: 2 x 25A
  • Connection Cable: 4 Sets x 2/0 AWG Cable for Breaker-to-Battery or Inverter Connection
  • Estimated Daily Energy Production: Approximately 16-17kWh (estimate based on the 4,440W array and 4 hours of sunlight, minus system losses)

Features

  • Dual paralleled 6500W inverters combine for a full 13,000W of split-phase 120V/240V output.
  • Space-saving wall-mounted PowerWall batteries free up floor space compared to rack or cabinet battery systems.
  • Four 100Ah 51.2V PowerWall lithium batteries provide 20.48kWh of usable energy storage.
  • Twelve 370W monocrystalline solar panels generate a 4,440W solar array for daily recharging.
  • Split-phase output supports both 120V and 240V household and workshop equipment.
  • Included mounting Z-brackets simplify secure solar panel installation.
  • Dual 200A DC breakers and 25A PV breakers support safe, code-ready system connections.
  • Heavy-duty 2/0 AWG cabling handles the higher current loads of this dual-inverter configuration.
  • Expandable design allows additional PowerWall batteries and solar panels as energy needs grow.
  • Complete off-grid starter package eliminates the guesswork of matching components.

Why Choose It?

This large-capacity kit combines two paralleled 6500W inverters with 20.48kWh of wall-mounted PowerWall battery storage and a 4,440W solar array for serious off-grid power. Its space-saving PowerWall design makes it especially well suited to installations where floor space for a battery rack is limited.

Recommended For

  • Whole-home off-grid living
  • Large cabins and remote homes
  • Workshops and light commercial buildings
  • Properties with limited floor space for battery racks
  • Expandable off-grid solar systems

Comfortably Powers

  • Central air conditioners
  • Well pumps
  • Refrigerators and freezers
  • Full kitchen appliance loads
  • LED lighting throughout a home
  • TVs, laptops, and desktop computers
  • Power tools and workshop equipment

Where It Falls Short:

This is a large-scale off-grid kit, so it requires meaningful installation space and planning rather than a simple plug-and-play setup. It's designed exclusively for off-grid use rather than grid-tied operation.

  • Requires ground or roof space for a twelve-panel solar array.
  • Requires wall space to mount all four PowerWall battery units.
  • Off-grid only; not designed for grid-tied interconnection.
  • Fixed component count; higher energy needs require purchasing additional batteries and panels separately.
  • Installation involves multiple major components, including dual inverters, breakers, and heavy-gauge wiring.
  • Estimated daily energy production is a sunlight-dependent estimate, not a guaranteed output.
