SunGoldPower 18000W 48V Split Phase Pure Sine Wave Inverter Charger

Description

The SunGoldPower 18000W 48V Split‑Phase Pure Sine Wave Inverter Charger (LFPV18K48V240VSP) delivers industrial‑grade power for off‑grid solar systems, whole‑house backup, and demanding commercial loads. Accepting a 240 VAC input, this low‑frequency inverter converts 48 V DC battery power into a clean 120/240 V AC split phase output, supplying two independent 120 V legs or a full 240 V for large appliances. A built‑in 120 A smart charger supports eight battery chemistries—including LiFePO₄, GEL, AGM, and lead‑acid—while Power Factor‑Corrected 4‑stage charging maximizes battery life. The integrated transfer switch provides an ultra‑fast 8 ms switchover between utility and battery, while Automatic Generator Start (AGS) and AC/Battery priority modes ensure uninterrupted power.

A Battery Temperature Sensor (BTS), remote control, and LCD display simplify monitoring. Engineered for safety with a 15‑second generator reconnection delay, this 18 kW pure sine inverter efficiently powers everything from sensitive electronics to heavy‑duty HVAC systems—making it the ultimate high‑capacity solution for off‑grid, backup, RV, and marine applications.

FAQs

Q. Can this inverter be connected to a multi-phase electrical system?
This inverter supports split-phase output (120V and 240V) only. It is not compatible with multi-phase systems such as three-phase power. Please ensure your electrical setup matches the inverter’s dual-phase output requirements.

Q. Is this inverter compatible with lithium batteries? Can the charge/discharge voltages be customized?
Yes, the inverter supports lithium batteries, including LiFePO₄ types. However, please note that the charging and discharging voltage curves are preset and cannot be manually adjusted. Thank you for your understanding.
