The SunGold Power 13kW 48VDC Off-Grid Solar Kit Pairs Two 6500W Inverters With 20.48kWh of Wall-Mounted Lithium Storage

The SunGold Power 13kW 48VDC Off-Grid Solar Kit is a complete off-grid system built around two 6500W split phase inverters. It includes twelve 370W monocrystalline black panels for a 4440W array, four 5.12kWh wall-mounted LiFePO4 batteries for 20.48kWh of storage, and the breakers, busbar, cables and mounting brackets that tie the system together.

SunGold estimates the array produces around 17.7kWh per day based on 4 hours of sun. That makes the kit a practical fit for a cabin, small home or remote property that needs 120/240V power and would rather hang batteries on a wall than fill a rack. The system is ready to grow, with room for more inverters, batteries and panels later.


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

Two 6500W Inverters for 13000W of Split Phase Power

Each inverter is rated at 6500W with a 13,000VA peak and a pure sine wave output of 120/240Vac, split phase or single phase. Working together, the pair delivers 13000W of continuous power. A typical 10ms switch time keeps loads running when the system changes power source.

Wall-Mounted 20.48kWh LiFePO4 Battery Bank

The four SG48100M batteries are 51.2V 100Ah lithium iron phosphate units of 5.12kWh each. SunGold rates them for at least 7000 cycles and a calendar life of 15 years or more. Each has an LCD and a built-in BMS that protects against overcharge, deep discharge, overload, overheating and short circuit. The included 400A busbar joins all four in parallel.

Twelve 370W Black Mono PERC Panels

The panels use 120 half-cut mono cells with a module efficiency of 20.31%. They have an IP68 junction box and passed load tests of 5400 Pa for snow and 2400 Pa for wind. SunGold's wiring diagram connects them as two strings of six panels in series, one string per inverter, with a 25A PV breaker on each.

Dual MPPT Charge Controllers in Each Inverter

Each inverter has two MPPT inputs rated 5000W each, with up to 550Vdc open circuit voltage and a 150 to 450Vdc operating range. SunGold rates MPPT tracking efficiency at 99.9%. SunGold's diagram uses one input per inverter, which leaves the second input on each unit unused.

Utility and Generator Input

Each inverter accepts a utility or generator connection that can power loads and charge the batteries at up to 80A, with a maximum mixed charge current of 140A. Four charging modes, four output modes and a time-slot charge and discharge function let you decide when solar, battery or AC power takes priority.

Built for Expansion

Up to six identical inverters can be paralleled for 120V single phase, 120/240V split phase or 208V three phase output. Three phase needs more than three units. The batteries support up to 63 units in parallel, so storage can grow with your loads.


Real-World Applications

Off-grid cabins. Power lighting, a refrigerator, a TV and fans at a remote cabin with 20.48kWh of storage for evening use.

Rural homes with a generator. Run household 120V and 240V loads from solar and let a generator recharge the batteries during long cloudy stretches.

Tight installation spaces. Wall-mounted batteries keep the floor clear in a utility room, garage or small equipment shed.

Starter systems. Begin with a 4440W array and add panels, batteries or inverters as your needs grow.


How It Compares to Common Alternatives

Versus buying components separately. This kit matches the inverters, batteries, panels, breakers, busbar and cables in one order, with a wiring diagram for the complete system.

Versus a single 6500W inverter. Paralleling two inverters doubles continuous output to 13000W and gives you four MPPT inputs instead of two.

Versus rack-mounted batteries. Rack batteries need a cabinet or rack. These batteries mount on a wall and link through the included busbar.


Is This Solar Kit the Right Fit

  • Indoor equipment space. The inverters are IP20 rated for indoor use only, and each battery weighs 114.6lbs, so the wall must carry the load.
  • Roof or ground space. Each panel measures 63.23 x 44.65 x 1.38 inches, and the kit includes twelve.
  • Daily energy. Plan loads around roughly 17.7kWh per day of solar production at 4 hours of sun.
  • Installation. SunGold's manual calls for installation that complies with local requirements and regulations.

This may be a good fit if

  • You need 120/240V split phase power off the grid
  • You prefer wall-mounted batteries
  • You want a generator or utility backup input
  • You plan to expand the system later

Common Questions

How Much Energy Does This Kit Produce per Day?

SunGold estimates around 17.7kWh per day based on 4 hours of sun. Actual output depends on location, season and panel placement.

Can I Add More Inverters Later?

Yes. Up to six identical inverters can run in parallel. Paralleled inverters must share the same battery bank, and each inverter needs its own independent PV array.

Can I Connect a Generator?

Yes. The AC input on each inverter accepts a utility or generator source, which can power loads and charge the batteries.

Do the Batteries Communicate With the Inverters?

The inverter supports CAN and RS485 communication with SunGold Power batteries, and the SG48100M offers RS232, RS485 and CAN ports.
