SunGold Power 15KW 48V Split Phase Inverter

The SunGold Power 15KW 48V Split Phase Inverter Handles 15000 Watts of Continuous Load and 45KW Surges for Large Homes and Businesses

The SunGold Power 15KW 48V Split Phase Inverter combines a 15.0KW pure sine wave inverter, an AC battery charger and an auto-transfer switch into one LF-PV Series system. It runs from a 48V battery bank, takes 240V from the grid or a generator, and outputs 120V and 240V split phase power for a standard home or business panel.

SunGold aims it at the big loads in home and business applications, such as refrigerators, freezers, microwaves, dryers, air conditioners and pumps. It works as the center of a backup system, or as the inverter in an off-grid system that uses a separate solar charge controller.

SunGold Power 15KW 48V Split Phase Inverter Features

15KW Output With a 45KW Surge

Continuous output is 15.0KW, and the surge rating is 45.0KW for 20 seconds. That reserve covers the start-up current of large compressors and pumps.

100A Charger With 4-Step Charging

The AC battery charger is rated 100±5Amp, selectable from 0% to 100%. Power factor correction and a 4-step charging profile manage the 48V bank, and the selector covers lithium LiFePO4, gel, AGM and lead acid batteries.

80A Bypass and 100A Charger Breakers

SunGold's manual lists an 80A bypass breaker for the 15KW model, which protects the AC pass-through circuit. The charger is protected by a 100A breaker.

Generator Mode for Wide-Range Input

In its generator setting, SW2 lets the inverter pass through AC with a wide voltage and frequency range, so a generator's power does not cause frequent switching to battery. The utility setting keeps a narrower range for sensitive loads.

Power Saver and Night Charger Settings

Idle draw is 225W with power saver off and 45W with it on. SW3 chooses between load sensing every 3 seconds and a night charger mode that does not power loads from the battery, but charges the bank and passes AC through whenever qualified AC is present.

Auto Generator Start, Remote and BTS

The inverter can start a compatible generator when the battery gets low and stop it after charging. The included remote control and battery temperature sensor cable round out the system.

Real-World Applications

Large homes. Back up a full 240V panel with air conditioning, pumps and kitchen appliances.

Shops and commercial spaces. Keep 240V equipment and 120V lighting running during outages.

Generator-backed off-grid systems. Run from the battery bank and let the generator start automatically when the bank needs charging.

Solar homes with a separate controller. Use battery priority to draw from the bank first, with the grid as backup.

How It Compares to Common Alternatives

Versus the 12KW model. SunGold's manual rates the 12KW at 12.0KW continuous with a 36.0KW surge, a 60A bypass breaker and 180W idle draw with power saver off. This model adds 3KW of output and a larger bypass breaker.

Versus the 18KW model. The 18KW raises output to 18.0KW with a 54.0KW surge and a 100A bypass breaker. It weighs 197 LB, against 176.6 LB for this model.

Versus combining two smaller inverters. Two of these units cannot be connected together for more output, so size the single inverter for your full load from the start.

Is This Split Phase Inverter the Right Fit

• Battery bank. Requires a 48V bank. The low battery alarm sits at 42.0Vdc or 44.0Vdc depending on settings.
• AC input. 240V only, not suitable for 120V input, within 184-253Vac or 140-270Vac.
• 120V circuits. When wired for 120V on one hot line, that line can carry at most half the rated capacity.
• Solar. No built-in MPPT. Solar panels need an external charge controller.
• Installation. Indoor use only. 176.6 LB and 28.7 x 16.5 x 8 inches, wall mounted.

This may be a good fit if

• Your loads need up to 15KW continuous
• Your home or business has a 240V panel
• You run a 48V battery bank
• You use a generator for backup charging

Common Questions

Does It Support Multiple Phase Systems?

No. It only has dual phase output, 120V and 240V, so it cannot connect to a multiple phase system.

Does It Work With Lithium Batteries?

Yes. Use the LiFePO4 setting for lithium batteries. The charge and discharge voltages cannot be adjusted beyond the preset battery types.

Can Two Units Be Connected Together for More Power?

No. Two units cannot be combined for higher continuous output.

Does It Include a Solar Charge Controller?

No. This model comes without MPPT, so solar charging needs a separate controller connected to the battery bank.

Why Is There a Delay Before Transferring to Generator Power?

The 15-second delay gives a generator time to spin up to a stable voltage and keeps the relay from chattering. The inverter will not transfer until it locks onto the generator's output.
