SunGold Power High Voltage 11.4KW Hybrid Split Phase Inverter With APS Transmitter

The SunGold Power High Voltage 11.4KW Hybrid Split Phase Inverter With APS Transmitter Pairs 120-500V Lithium Batteries With Four MPPTs and Built-In Rapid Shutdown

The SunGold Power High Voltage 11.4KW Hybrid Split Phase Inverter With APS Transmitter (model SG11.4KHB-HV) is a residential hybrid inverter for high-voltage lithium-ion batteries from 120V to 500V. It delivers 11.4kW of continuous 120/240V output, supports up to 18kW of PV on four MPPT inputs, and has an integrated rapid shutdown transmitter.

It is made for homeowners and installers who want self-consumption, backup power when the grid fails, and the option to run fully off grid with a generator. It can be AC-coupled to an existing solar system or DC-coupled with new PV, and up to three units can run in parallel.

SunGold Power High Voltage 11.4KW Hybrid Split Phase Inverter With APS Transmitter Features

11.4kW Continuous With 18.2kVA for 10 Seconds

Rated output is 11.4kW and 47.5A at 240V split phase, both on grid and in backup or off-grid mode. Maximum apparent output is 18.2kVA for 10 seconds, and the backup switch time is under 10ms. The backup output handles unbalanced loads up to half the rated output on each phase.

Four MPPTs With 18,240W of Recommended PV

Four MPPT inputs each take one string, with a 600V maximum input voltage, an 80-550V MPPT range and 16A per string. Recommended maximum PV power is 18,240W. PV efficiency peaks at 97.6%, and PV-to-battery charging peaks at 98.5%.

High-Voltage Lithium Battery Support

The battery port works with lithium-ion batteries from 120V to 500V at up to 50A of charge or discharge current, with CAN or RS485 communication. Depending on the battery model, the inverter can connect with 10 to 150kWh of storage.

Integrated Rapid Shutdown Transmitter

A built-in transmitter sends a signal up the PV strings to module-level receivers. Pressing the red rapid shutdown switch turns the transmitter off and ramps the PV voltage down, and an external switch can be added where the inverter is out of reach. The receivers must match the transmitter brand.

Energy Arbitrage and Export Control

Choose Self-Use (the default), Peak-Shaving or Feed-in-Priority mode. The included energy meter and two current transformers let the inverter limit exports or hold net export near zero, with or without a battery.

Generator Support and AC or DC Coupling

A generator can act as the grid source during outages or in off-grid systems, supplying loads and recharging the battery. The inverter can also be AC-coupled to an existing PV system, with frequency-watt shifting to manage that system in backup mode.

Type 4X Enclosure With Natural Convection Cooling

The enclosure is rated TYPE 4X (IP66) and cooled by natural convection, so there is no fan noise. Typical noise is under 30 dB(A), the operating range is -13 to 140°F, and it is rated for altitudes up to 13,120 ft.

Real-World Applications

Homes with high-voltage battery storage. Store solar in a 120-500V lithium battery and draw on it in the evening.

Retrofitting an existing PV system. Replace an old string inverter, or AC-couple the hybrid with a battery to add storage.

Areas with export limits. Use the energy meter to cap exports or run near zero export.

Remote off-grid homes. Run from PV and battery with a generator to supplement and recharge.

Whole-home or partial-home backup. Back up selected circuits or the whole house from a backup load center.

How It Compares to Common Alternatives

Versus SunGold's 48V 11.4KW hybrid. That model runs on a 48V battery bank with 200A grid pass-through. This model works with 120-500V high-voltage batteries at up to 50A, adds a fourth MPPT and an integrated rapid shutdown transmitter, and weighs 71.74 lbs.

Versus a grid-tie string inverter. This hybrid can run as a grid-tie PV inverter with export control and no battery. Adding a battery gives it backup power and energy arbitrage.

Versus an off-grid-only inverter charger. An off-grid unit does not export to the utility. This model carries UL 1741 SB, IEEE 1547.1-2020 and California Rule 21 listings for grid-interactive use.

Is This Hybrid Inverter the Right Fit

• Battery. Requires a compatible high-voltage lithium-ion battery from 120V to 500V. A battery is needed for backup or off-grid power.
• Solar array. Up to four strings, one per MPPT, at no more than 600V and 16A each. Module-level rapid shutdown needs receivers that match the transmitter.
• Grid. 240V split phase service with an AC input range of 211-264V and up to 71.3A of input current.
• Monitoring. Setup uses Bluetooth. The SunGold data logger for Wi-Fi monitoring is sold separately.
• Size and weight. 29.53 x 22.05 x 8.66 inches and 71.74 lbs.

This may be a good fit if

• You use or plan a high-voltage lithium battery
• You need built-in rapid shutdown
• Your array splits into up to four strings
• You want an outdoor-rated, fanless inverter

Common Questions

What Batteries Does It Work With?

High-voltage lithium-ion batteries from 120V to 500V with CAN or RS485 communication. Depending on the battery model, it can connect with 10 to 150kWh of storage.

Can It Provide Backup Power Without a Battery?

No. With PV only, it works as a grid-tie inverter and cannot power the home during an outage. With a battery, it can supply backup power even if no PV is connected.

How Many Units Can Be Paralleled?

Up to three inverters can be installed in parallel on the backup side of the system. AC coupling is currently supported on a single hybrid system only.

How Does the Rapid Shutdown Transmitter Work?

The transmitter sends a signal over the PV strings while the inverter has AC power. When the signal stops, the module receivers switch off and each module drops to around 0.6Vdc.
