Sungold Power · SGKT-3PRO
A complete 24V solar system — 3,000W inverter with built-in 80A MPPT solar charging, 5.12kWh of Bluetooth-enabled LiFePO₄ battery storage, and four 200W monocrystalline panels.
This 24V solar kit provides higher efficiency for larger setups. For a 12V alternative, we also offer the Sungold Power 3000W Off-Grid Solar Kit 12VDC 600W Backup. For even more options, check out our complete Sungold Power Kits collection.
Rated output with double the power available briefly for motor starts and other high-draw moments.
Automatically switches from grid to off-grid power within 10 milliseconds to keep electronics running.
Built-in solar charge controller, room to add panels beyond the 800W (4×200W) included here.
Charges from mains or a generator, with automatic generator auto-start via dry contact.
Each battery pairs with a mobile app for live voltage, SOC, and temperature data.
Automatically warms below 33.8°F and stops above 42.8°F, protecting cold-weather charging performance.
Confirmed for the 24V 100Ah battery line, with a 100A BMS providing comprehensive protection.
Grade-A monocrystalline cells backed by a tiered 25-year output warranty.

This 24V solar kit provides higher efficiency for larger setups, per the manufacturer's own description — well suited for RVs, cabins, small homes, and emergency backup power.
Yes — four 200W monocrystalline panels (800W total) are included, and the inverter's built-in 80A MPPT controller supports up to 4,000W of solar input if you add more later.
5.12kWh combined from two 24V 100Ah batteries with Bluetooth monitoring.
Yes — it includes UPS functionality, automatically switching from grid to battery power within 10 milliseconds.
Yes — the manufacturer also offers a 12V version, the Sungold Power 3000W Off-Grid Solar Kit 12VDC 600W Backup, for setups that don't need the higher efficiency of a 24V system.
Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
We installed our 3000 W 24 V Solar kit at our home in Costa Rica. Power disruptions are normal and the SunGold system seamlessly takes over. We have the unit on an emergency circuit to run the fridge, router, light panel and ceiling fans.
