SunGoldPower 8000W Off-Grid Solar Kit | 120V/240V Split-Phase | 10.24–16.07kWh LiFePO4
Power a remote cabin, tiny home, workshop or other off-grid property with an integrated solar generation and battery storage package. The SunGoldPower SGR-8K series pairs an 8,000W 48V inverter with eight 450W N-Type bifacial solar panels (3,600W total) and a choice of three LiFePO4 battery configurations. Select the battery option that matches your storage and installation needs.
Key Features
-
8,000W AC power: 120V/240V split-phase output for compatible household and workshop loads.
-
3.6kW included solar array: eight 450W bifacial N-Type monocrystalline modules; estimated generation is up to approximately 14.4kWh per day with four equivalent hours of full sunlight before real-world losses.
-
Your choice of battery storage: 10.24kWh rack-style or tower-style LiFePO4, or a 16.07kWh PowerMax outdoor battery.
-
Dual MPPT inverter: supports up to 11,000W PV input per the manufacturer, allowing room for appropriately designed solar expansion beyond the included 3,600W array.
-
Monitoring and scalability: Wi-Fi monitoring and support for up to six compatible inverters connected in parallel, subject to proper system design.
-
Kit accessories included: solar extension cables, panel Z-brackets and DC/PV protection components listed below.

Frequently Asked Questions
Is this a grid-tied or hybrid solar kit?
No. The SGR-8K series is sold as an off-grid kit. Do not assume utility-grid export, grid-interconnection approval or grid-connected residential backup compatibility. For a utility-connected installation, ask us about suitable grid-connected hybrid alternatives.
How much energy will the panels produce each day?
The eight panels total 3.6kW of rated solar capacity. At four equivalent peak-sun-hours, the theoretical gross generation is about 14.4kWh/day. Actual production will be lower or higher depending on location, season, panel direction, shade, temperature and system losses.
How long will the batteries power my appliances?
Runtime depends on the selected 10.24kWh or 16.07kWh battery, loads, usable state of charge, inverter efficiency and other conditions. Share your appliance wattages and expected daily usage with us for sizing assistance.
Can the inverter and battery system be expanded?
The manufacturer states the inverter can be paralleled with compatible units and the system can be expanded with compatible batteries and solar panels. Follow the model-specific installation, wiring and communication requirements before expanding.
Does this kit include professional installation?
No installation service is implied by the kit contents. Installation should be planned and performed by a qualified solar/electrical professional in accordance with local codes, the supplied manuals and any applicable permits.
Need Help Choosing the Right Kit?
Contact OffGrid Lux before ordering if you would like help checking your energy requirements, choosing between the three battery options, or confirming compatibility for your site. Manufacturer specifications and supplied accessories may be updated; refer to the latest official documentation for final installation details.
