SunGold Power 5kW Off-Grid Solar Kit vs SunGold Power 10kW Off-Grid Solar Kit

Buy the 5kW kit for a cabin, tiny home or 120V-only off-grid build where a fridge, lights and small loads are the whole job. Buy the 10kW kit for a whole house that needs 240V for a well pump, HVAC or shop tools, or that may grow later. The 10kW is the stronger system on every electrical measure: split-phase output, 20,000W surge, two MPPVs, 11kW of solar headroom, UL1741 listing and parallel capability up to six units. The 5kW is simpler and smaller, and its bifacial panels suit ground mounts and reflective surfaces. Owners of both kits praise SunGold's tech support and design help.

  • Choose the SunGold Power 5kW kit if your loads are all 120V and a 10.24kWh bank with 2.7kW of bifacial panels covers your cabin or tiny home.
  • Choose the SunGold Power 10kW kit if you need 240V split-phase for a well pump, HVAC or shop equipment, or want room to expand to a whole-house system.

Questions and answers

Which kit is better for a cabin or tiny home?
The 5kW kit. Its 120V output and 10.24kWh bank cover lights, a fridge and small appliances, and it is far less to mount and wire. Step up to the 10kW only if you need 240V or plan to grow.
Can the 5kW kit run a well pump or central AC?
No. It outputs 120V only, so 240V loads like a well pump, central AC, electric dryer or electric water heater will not run. The 10kW kit's split-phase output handles them.
Which lasts longer off-grid without sun?
The 10kW kit. Its 25.6kWh bank runs a refrigerator about six days, against a bit over two days for the 5kW kit's 10.24kWh. Both recharge from solar once the sun returns.
Is the 10kW kit worth stepping up to?
Yes if you need 240V, whole-house capacity, cold-weather charging or future expansion. It also adds UL1741 listing and parallel capability. For a 120V-only cabin, the 5kW kit does the job with less cost and complexity.
Which handles cold weather better?
The 10kW kit, if you pick the self-heating battery version, which keeps charging down to 14°F. The 5kW kit uses standard LiFePO4 cells that stop accepting charge below freezing.
Can either system be expanded later?
The 10kW inverter accepts up to 11,000W of solar and parallels up to six units for 60kW. The 5kW inverter accepts 5,500W of solar, about 2,800W more than the included panels, but does not parallel.
