Sungold Power 12,000W 48V Split-Phase Inverter Charger

Power demanding 120/240V loads with a low-frequency, split-phase inverter/charger designed for off-grid and backup applications. The Sungold Power LF-PV series combines an inverter, high-current AC charger, and auto-transfer switch in one complete system (without MPPT)—built to handle large appliances, motor loads, and quick changeovers when utility power drops.

Key Features & Benefits

• 12,000W continuous power — Run large home or business loads without constantly load-managing.

• 36,000W surge (20s) + low-frequency transformer design — Helps start and support high-inrush equipment like pumps, dryers, and air conditioners more reliably.

• Split-phase 120/240V output — Powers both 120V circuits and 240V appliances from one inverter platform.

• 240VAC input (not suitable for 120VAC input) — Ensures proper operation on 240V utility or generator sources designed for split-phase systems.

• Built-in auto-transfer switch + ~10ms typical transfer time (max) — Keeps power interruptions minimal for better continuity during outages.

• AC Priority (default) or Battery Priority selectable — Choose how your system behaves: maximize backup responsiveness or prioritize utility/generator charging.

• Built-in AC battery charger (115±5A) with selectable charge rate up to 120A (0%–100%) — Faster recharge options and more control to match battery bank size and generator capacity.

• 4-step intelligent charging + PFC (Power Factor Correction) — More efficient charging from grid/generator power and better charging behavior across conditions.

• Auto Generator Start (AGS) — Enables automated generator starts for hands-off backup workflows (when paired with a compatible generator setup).

• 8 battery voltage selections (LiFePO4, Gel, AGM, Lead Acid) — Flexible battery compatibility for new builds or upgrades.

• Remote Control + Battery Temperature Sensor (BTS) included — Easier monitoring/operation and temperature-aware charging support.

• 15s delay before transfer when AC recovers — Helps protect loads when used with generators as power stabilizes after recovery.
