A cabin-and-shop-sized package with 2.49kW of solar and 10.24kWh of storage.
Compare the exact capacity, output, package contents and installation requirements before ordering SunGoldPower 5kW Off-Grid Solar Kit — 2.49kW Panels + 10.24kWh Batteries, 120V (SGR-5KE).

Why it earns a closer look
Useful capability, explained in buying language.
Focused 120V design
The package avoids confusion for cabins and shops whose planned load center does not require native 240V from one inverter.
Meaningful storage from two rack batteries
Two SG48100P modules provide 10.24kWh rated energy with front displays and compatible communications.
Core protection and cable items included
The official BOM includes DC and PV breakers, cable sets, PV extensions, and panel Z-brackets.
Honest sizing language
Inverter kW, panel kW, and battery kWh are explained separately so buyers can model loads, production, and runtime correctly.

Where it fits
- Cabins and tiny homes with 120V loads
- Remote workshops and sheds
- Generator-assisted 120V off-grid systems
- Critical-load backup without utility export
System-fit guidance
Confirm voltage, phase, continuous and surge loads, solar-input limits, communications, environmental rating, code requirements and delivery access with the qualified installer before ordering.
What’s included
- 1 × SPH5048P 5,000W 48V DC / 120V AC inverter
