SunGold Power 10KW 48V Split Phase Solar Inverter

The SunGold Power 10KW 48V Split Phase Solar Inverter Delivers 10000 Watts of 120/240V Power With Up to 200A of Battery Charging

The SunGold Power 10KW 48V Split Phase Solar Inverter (model SPH10048P) is an all-in-one off-grid solar charge inverter. One wall-mounted unit combines a 10000W pure sine wave inverter, two MPPT solar charge controllers with 11000W of PV input, and a battery charger that runs from the grid or a generator. It is certified UL 1741 by ETL for off grid solar systems.

It is built for homes, cabins, farms and shops that need full 120/240V split phase power from a 48V battery bank. With 200A of charging and a 6HP motor rating, it suits larger banks and heavier loads, and up to six units can run in parallel for 60kW of output when your needs grow.

SunGold Power 10KW 48V Split Phase Solar Inverter Features

10000W Continuous With a 20000W Peak

The inverter is rated for 10000W of continuous output and a 20000W peak, with a loaded motor capacity of 6HP. That reserve helps with the starting surge of well pumps, compressors and shop tools. Output can be set to split phase (120/240V) or single phase (120V), and the phase voltage can be adjusted to 100, 105, 110, 115, 120 or 127VAC.

Two MPPT Inputs With 11000W of Solar Capacity

Two MPPT trackers accept a combined 11000W of PV. Each input takes up to 500Vdc open circuit and 22A, with a 125-425Vdc MPPT range. SunGold rates tracking efficiency at 99.9%, so more of your array's output reaches the battery and loads.

Up to 200A of Battery Charging

Solar charging reaches 200A, grid or generator charging reaches 120A, and hybrid charging is capped at 200A. Four charging modes are available: hybrid, utility priority, solar priority and solar only. High charge currents let you refill a large lithium bank in fewer hours of sun or generator run time.

Four Output Modes and Time-Slot Control

Choose utility priority, solar and utility hybrid, solar priority or inverter priority output. A time-slot function lets you set charging and discharging periods around local peak and valley tariffs. When the source changes, the typical switch time is 10ms, so most equipment keeps running.

Works With Lithium and Lead-Acid Batteries

The inverter supports 48V AGM or sealed, gel, flooded and LiFePO4 batteries, plus a user mode for custom settings. If a lithium battery has gone to sleep, grid or PV power can wake it up. CAN and RS485 ports allow communication with SunGold batteries.

Parallel Up to Six Units

Up to six inverters can be paralleled for 60kW of output as 120V single phase, 120/240V split phase or 208V three-phase. Paralleled units share one battery bank, and a parallel communication cable comes in the box.

Monitoring and Communication Ports

RS485, CAN, USB and dry contact interfaces are built in, along with a Wi-Fi port. SunGold describes the inverter as configured with Wi-Fi components for checking inverter data in a mobile app, and Wi-Fi and GPRS are also listed as optional external modules.

Real-World Applications

Whole-home off-grid power. Run a 120/240V panel with appliances, lighting and 240V loads from solar and a 48V battery bank.

Well pumps and HVAC. The 6HP motor rating and 20000W peak give room for motor starting loads.

Homes on time-of-use rates. Use the time-slot function to charge from the grid during low-rate hours and draw on the battery during peak hours.

Farms and workshops. Power 240V equipment from a large PV array, with a generator as a backup charging source.

Systems that will grow. Start with one unit and add more in parallel as demand increases.

How It Compares to Common Alternatives

Versus the 8KW model (SPH8048P). Both share the same dual MPPT input with 11000W of PV and a 500Vdc limit. The 10KW adds 2000W of continuous output, a 20000W peak instead of 16000W, a 6HP motor rating instead of 5HP, and 120A grid charging instead of 100A.

Versus separate components. One unit replaces a separate inverter, AC charger and two solar charge controllers, with a single display and one set of settings.

Versus a 120V-only inverter charger. A 120V unit cannot feed both legs of a standard home panel. This model supplies 120/240V split phase power for 240V appliances.

Is This Split Phase Solar Inverter the Right Fit

• Battery bank. Requires a 48V battery bank within 40-60Vdc. SunGold's manual calls for 70 mm² (00 AWG) battery cable and a 2P-250A breaker.
• Solar array. Two independent strings, each up to 500Vdc open circuit and 22A, for 11000W total.
• Location. IP20 rated for indoor use only, from 14 to 131°F with derating above 113°F.
• Size and weight. 17.9 x 26 x 5.1 inches and 54 lb, wall mounted.

This may be a good fit if

• You need 10000W of 120/240V split phase power
• You run a 48V lithium or lead-acid bank
• You have a large solar array
• You may add parallel units later

Common Questions

What Can a 10000W Inverter Power?

It can run household appliances, power tools, heating devices, computers, electronics and LED lighting, depending on their wattage. For motors and compressors such as refrigerators and power tools, SunGold advises keeping the starting surge under 10000W.

How Efficient Is It?

MPPT tracking efficiency is 99.9%, and maximum battery inverter efficiency is 92%.

Can It Be Used in Parallel?

Yes. Up to six units can be paralleled for 60kW, for 120V single phase, 120/240V split phase or 208V three-phase output.

Can Paralleled Inverters Share a Solar Array?

No. Each inverter needs its own PV array, and the PV1 and PV2 inputs on each inverter must also be independent. All paralleled units must connect to the same battery bank.
