SunGold Power 13kW 48VDC Off-Grid Solar Kit | 6300W Solar

The SunGold Power 13kW 48VDC Off-Grid Solar Kit Combines a 6300W Bifacial Array With 20.48kWh of Cabinet-Housed Battery Storage

The SunGold Power 13kW 48VDC Off-Grid Solar Kit brings together two 6500W split phase inverters, fourteen 450W bifacial N-type solar panels and four 5.12kWh server rack LiFePO4 batteries. The batteries ship with an enclosed cabinet, and the kit includes the breakers, cables and Z-brackets needed to connect everything.

SunGold describes this size of system as powerful enough to run air conditioners, well pumps, a refrigerator, a TV, a workshop and a home office. It suits homeowners going fully off-grid who want a tidy battery installation and a solar array that can collect light on both sides of each panel.

SunGold Power 13kW 48VDC Off-Grid Solar Kit Features

Bifacial N-Type Panels That Collect Light on Both Sides

Each 450W panel uses N-type monocrystalline cells with a module efficiency of 22.5%. SunGold says the rear side can harvest up to an additional 30% energy where it is exposed to reflected light. The dual glass build is certified for 5400 Pa snow loads and 2400 Pa wind loads.

Server Rack Batteries in an Enclosed Cabinet

The four SG48100P batteries are 51.2V 100Ah lithium iron phosphate modules, 5.12kWh each, for 20.48kWh in total. They are rated for at least 7000 cycles and a 15-year design life. SunGold lists UL1973, UL9540A, CE and UN38.3 for the batteries, and the enclosed cabinet keeps all four in one housing.

13000W of Split Phase Output From Two Inverters

Each inverter is rated at 6500W with a 13,000VA peak and pure sine wave 120/240Vac output. Paralleled, the pair supplies 13000W of continuous power for 240V appliances and 120V circuits, with a typical 10ms switch time.

Simple Two-String Solar Layout

SunGold's wiring diagram connects the panels as two strings of seven in series. Each string runs through a 25A PV breaker to one MPPT input on its own inverter. Each MPPT input handles up to 5000W and 550Vdc open circuit, with 99.9% tracking efficiency.

Charge From Solar, Utility or Generator

Each inverter can charge the batteries from a utility or generator at up to 80A, with a maximum mixed charge current of 140A. A time-slot function lets you schedule charging and discharging around local peak and off-peak rates.

Communication With SunGold Batteries

The inverters support CAN and RS485 communication with SunGold Power batteries. The SG48100P has a built-in BMS that monitors cell voltage, current and temperature and protects against overcharge, deep discharge, overload, overheating and short circuit.

Real-World Applications

Full-time off-grid homes. Run 240V loads such as a well pump or air conditioner alongside everyday 120V circuits.

Home workshops and offices. Keep tools, computers and lighting on solar power through the day and battery power at night.

Sites with reflective ground. Bifacial panels on ground mounts or flat roofs can pick up extra light from below.

Generator-assisted properties. Use a generator to top up the 20.48kWh bank during long stretches of poor weather.

How It Compares to Common Alternatives

Versus single-sided panels. A standard panel only uses light on its front face. These bifacial panels can add rear-side output where the back of the array is exposed.

Versus loose rack batteries. The included enclosed cabinet houses all four batteries, so you do not need to source a separate rack.

Versus a single 6500W inverter. Two paralleled inverters double continuous output to 13000W and give the system four MPPT inputs instead of two.

Is This Solar Kit the Right Fit

• Indoor equipment space. The inverters are IP20 rated for indoor use only, and the batteries are IP20 battery boxes.
• Array space. Each panel measures 69.37 x 44.65 x 1.38 inches and weighs 53.35 lbs, and the kit includes fourteen.
• Rear exposure. The bifacial gain depends on light reaching the back of the panels.
• Installation. Follow local requirements and regulations when installing the inverters, as SunGold's manual directs.

This may be a good fit if

• You want 13000W of split phase power off the grid
• You prefer batteries housed in a cabinet
• You have space for a 6300W ground or roof array
• You may add inverters, batteries or panels later

Common Questions

What Can This Kit Power?

SunGold says this size of system can run air conditioners, well pumps, a refrigerator, a TV, workshop equipment and office equipment. Each inverter can handle a 13,000VA peak for motor starts.

Can the System Be Expanded?

Yes. Up to six identical inverters can be paralleled for 120V single phase, 120/240V split phase or 208V three phase, which needs more than three units. Each inverter needs its own independent PV array, and all paralleled inverters share one battery bank.

Are the Solar Panels Waterproof?

Yes. SunGold confirms the panels are waterproof, and the junction box is IP68 rated.
