The SunGold Power 13kW 48VDC Off-Grid Solar Kit (SGR-13KM) is a complete off-grid solar kit built around two 6500W split-phase all-in-one inverters (SPH6548P) running in parallel. It includes 14 x 450W bifacial N-type monocrystalline solar panels for 6,300W of solar, 4 x 51.2V 100Ah LiFePO4 server rack batteries (SG48100P) for 20.48kWh of storage, and the breakers, cables, and mounting hardware SunGold lists for the system.
SunGold describes this as a complete off-grid home system. Two 6.5kW inverters in parallel provide 13kW of split-phase output, and four server rack batteries in an enclosed cabinet provide 20.48kWh of storage.
The SPH6548P is a 6500W all-in-one inverter with 120/240VAC split-phase pure sine wave output and 13,000VA of peak power. Two built-in MPPT channels accept up to 5,000W of solar each, and the unit charges batteries from solar, the grid, or a generator at up to 140A combined. It is certified to UL1741 and includes Wi-Fi monitoring. The kit includes two units for 13kW of combined output.
Each SG48100P is a 51.2V, 100Ah (5.12kWh) lithium iron phosphate battery in a 3U server rack format. SunGold rates it for 7,000 or more cycles at 80% depth of discharge with a 15-year design life, and it communicates with the inverter over RS485 or CAN. It is certified to UL1973 and is rated IP20 for indoor installation. Four batteries combine for 20.48kWh of storage, housed in the included enclosed battery cabinet.
The 450W bifacial N-type panels (SGN-450-BDG5) use 96 N-type monocrystalline cells and can collect reflected light from the rear side when mounted with open space behind them. Each panel is UL61730 and CEC listed and carries a 12-year material and workmanship warranty with a 30-year linear power warranty. At four peak sun hours, the 14-panel array produces about 25.2kWh per day. Actual output depends on location, season, tilt, and shading.
The inverters have built-in MPPT solar charging, so the panels connect directly to the inverters without a separate charge controller. That keeps wiring simpler and reduces the number of components to mount.
SunGold includes DC and PV breakers, battery and inverter cables, 50-foot solar extension cables, and Z-brackets for mounting the panels, all sized for this kit. SunGold also publishes a wiring diagram for the kit on its website. Having matched protection and cabling in the box saves sourcing time and helps keep the installation consistent.
Up to six SPH6548P inverters can be paralleled as your loads grow. SunGold lists up to 32 SG48100P batteries in parallel, so storage can grow with your needs. Add panels within the inverter solar input limits as your energy use grows.
Off-grid homes. Run household loads including refrigerators, washers, and well pumps.
Homesteads and farms. Power barns, shops, and pumps far from the grid.
Whole-home backup. Keep power on through extended outages.
Workshops and offices. Support tools, computers, and HVAC loads.
Versus buying components separately. A kit pairs an inverter, batteries, and panels that SunGold has matched for voltage and current, with breakers and cables sized for the system and a published wiring diagram.
Versus a fuel generator alone. Solar and batteries run quietly with no fuel deliveries. Many off-grid owners still keep a generator for long cloudy stretches, and the inverter can charge the batteries from one.
Versus the SGR-13K25S. The SGR-13K25S has the same inverters with 20 panels and five batteries (25.6kWh).
This may be a good fit if
At four peak sun hours, the 6,300W array produces about 25.2kWh per day. Production varies with your location, season, and panel orientation.
No. Solar charging is built into the inverters.
SunGold lists up to 32 SG48100P batteries in parallel, so storage can grow with your needs.
Yes. The inverters accept AC input from the grid or a generator to charge the batteries and pass power to loads.
No. The kit ships as components. We recommend a qualified electrician for installation and permitting.
The SunGold Power 13kW 48VDC Off-Grid Solar Kit brings together the inverter, batteries, panels, and protection an off-grid system needs. At Outbound Power, we help customers size solar kits, plan battery banks, and choose the right accessories. If you have questions, our team is happy to help.
