PowerCore 18K-48 · Buyer decision facts
SunGoldPower PowerCore 18K-48 | 18kW Three-Phase
PowerCore 18K-48 is an 18kW, 120/208V three-phase off-grid inverter for a 48V battery system. It is not a standard 120/240V split-phase residential output; confirm your distribution panel and three-phase loads before ordering.
Two MPPT trackers support up to 28.8kW total PV input per the manufacturer. Check each string’s voltage and current, battery-side charging and discharge limits, generator or smart-load configuration, and qualified installation requirements.
For split-phase 120/240V applications, compare the FR12K-B 12kW inverter.
Built for battery systems
A practical match for solar storage builds where the inverter needs to work smoothly with a dedicated battery bank.
Ready for real loads
Designed for customers powering appliances, tools, electronics, and essential circuits instead of small one-off devices.
Built to anchor your power system
A strong inverter is the part of the system that customers notice when the power actually has to work. This model is built for dependable conversion in solar and storage projects where the system needs to support more than basic charging.
- Use it as the core conversion point for a battery-backed power system.
- A practical fit for backup power, off-grid power, workshops, mobile builds, and residential energy projects.
- Helps keep system design cleaner when you need dependable AC output from stored energy.

Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
What should a buyer understand first about the PowerCore 18K-48's architecture?
It combines 48V battery conversion with the solar-charging, AC-input, and operating modes published for this exact model. That can reduce separate equipment, but it does not eliminate array design, battery protection, transfer planning, or permitting.
Can a small 48V battery support the PowerCore 18K-48 at full AC load?
The 48V bank must support the inverter's continuous DC demand, startup surge, and conversion loss without exceeding battery or BMS limits. Size parallel batteries, busbars, short copper conductors, lugs, disconnects, and fusing as one high-current circuit.
How should published AC loads be divided on the PowerCore 18K-48?
This listing is identified for published AC output. Verify appliance voltage, frequency, neutral and grounding requirements, and any hardwire or transfer limits before connecting it to a distribution system.
Which cold-weather solar limit matters on the PowerCore 18K-48?
This model includes solar-charging or hybrid functions described on its exact listing. Build the array from the published MPPT voltage window, cold-weather open-circuit voltage, input-current limits, tracker layout, and permitted PV power—not from panel wattage alone.
Who should commission the PowerCore 18K-48 in a whole-home installation?
No inverter should be assumed suitable for unrestricted grid export or direct panel connection. Confirm the PowerCore 18K-48's listed operating modes, transfer rating, neutral-ground behavior, overcurrent protection, rapid-shutdown or disconnect requirements, permits, and utility rules with a qualified installer.
