SunGoldPower Split-Phase Inverter Charger | 18000W Pure Sine Wave | 48V DC–120/240V AC

High-Capacity Off-Grid Power Inverter for Residential & Commercial Applications

The SunGoldPower LFPV18K48V240VSP is an 18,000W low-frequency split-phase pure sine wave inverter charger engineered for whole-home power, large offices, RVs, and off-grid setups. Combining a high-capacity inverter, intelligent AC battery charger, and built-in transfer switch, this all-in-one system provides reliable, uninterrupted AC power for high-demand residential, commercial, and mobile applications.

Ideal for solar-powered systems and off-grid or emergency backup scenarios, this inverter delivers massive continuous power with high surge capacity while maintaining exceptional efficiency, durability, and safety.

Key Features

18kW Continuous Power & 54kW Surge Capacity: 18,000W continuous power with 300% surge for 20 seconds, supporting multiple appliances and heavy-duty loads.
Split-Phase 120V / 240V Output: Dual-leg AC output compatible with residential and commercial setups, supporting 110/120V or 220/230/240VAC.
True UPS Function & Seamless Transfer: Built-in transfer switch automatically engages backup power during outages with no noticeable interruption.
High-Efficiency Low-Frequency Inverter: Peak DC-to-AC efficiency of 90%, idle consumption of 270W, and average THD of 3% for stable power to sensitive electronics.
100A Built-In Smart Battery Charger: Efficiently recharges multiple battery types from grid or generator with 0–100% charge control.
AC / Battery Priority Modes (SW5): Switch between AC priority (utility first) or battery priority (solar/off-grid) for optimal energy management with smooth transitions.
Direct-Connect Terminal Block: Enables scalability beyond 18kW, delivering up to 54,000W surge for emergency backup.
Automatic Generator Start (AGS): Starts a generator automatically when battery voltage drops and stops when fully charged for autonomous operation.
Durable Design for Long-Term Operation: Built to last 10+ years under demanding conditions for residential, commercial, and mobile off-grid systems.
Flexible Applications: Powers lights, appliances, and equipment in off-grid homes, cabins, RVs, trailers, mobile offices, or industrial setups.

Ideal Applications

Whole-home or large office backup power
Off-grid homes, cabins, or remote workshops
RVs, trailers, and mobile offices
Solar-powered energy storage systems
Emergency backup for critical electronics and appliances
Industrial and commercial off-grid installations

Understanding Your Power Needs

Power Calculation Guide

Sizing Metric	Formula & Example
Energy Consumption (Wh)	Formula: Watts × Hours Example: 60W × 4 hrs = 240 Wh
Battery Capacity (Ah)	Formula: Watt-hours ÷ System Voltage (V) Example: 240 Wh ÷ 12V = 20 Ah
Inverter Size (W)	Formula: Total Watts × 1.25 (safety margin) Example: 300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W)	Formula: Sum of all appliance watts used simultaneously Example: Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery	Formula: (Battery Ah × Voltage) ÷ Total Load (W) Example: (100Ah × 12V) ÷ 240W = 5 hrs

Find Your Power Match

Need / Application	System Recommendation
Basic lighting + phone charging	Recommended Battery: 50Ah – 100Ah (12V) Inverter Size: 100W – 200W Notes: For small backup setups
Home office (laptop, fan, TV)	Recommended Battery: 150Ah – 200Ah (12V or 24V) Inverter Size: 500W – 1000W Notes: For moderate usage with 4–6 hours of backup
Home backup (fridge, lights)	Recommended Battery: 200Ah+ (24V or 48V recommended) Inverter Size: 1000W – 1500W Notes: Ideal for longer backups or heavier loads
Business / shop power backup	Recommended Battery: 300Ah+ (48V system) Inverter Size: 2000W – 3000W Notes: Suitable for commercial setups or extended power outages
