SunGoldPower Solar Inverter | 12kW 48V | Off-Grid Split-Phase 120/240V

High-Capacity 12kW All-in-One Off-Grid Solar Inverter for Residential, Commercial, and Remote Applications

The SunGoldPower FR12K-B is a powerful 48V all-in-one off-grid solar inverter engineered for whole-home backup, off-grid, and hybrid solar systems. Delivering 12,000W continuous output and up to 24,000W peak power, this inverter supports both single-phase (120V) and split-phase (120/240V) configurations, making it ideal for homes, workshops, cabins, and small commercial installations.

Featuring dual MPPT solar inputs, UPS-level fast switching, and wide battery compatibility, the FR12K-B provides reliable, efficient, and scalable energy management for high-demand loads. Parallel expansion support allows you to scale your system as energy needs grow.

Key Features

12kW Continuous Output: Delivers stable 12,000W rated power with 24,000W peak for demanding appliances and equipment.
Split-Phase 120/240V Output: Supports single-phase and split-phase configurations for flexible whole-home power solutions.
Dual MPPT Solar Inputs: Two MPPT channels support up to 13,200W of solar input for maximum energy harvesting.
Wide Battery Compatibility: Works with 48V lithium-ion, lead-acid, and user-defined battery systems.
Fast UPS-Level Switching: Typical 10ms transfer time ensures smooth power transitions during outages.
Parallel Expansion Support: Connect up to 6 units for higher output capacity and system scalability.
Built-In Protection & Reliability: Advanced safeguards against overload, short circuits, and over-voltage.
Ideal Applications: Whole-home off-grid power, residential energy storage, small commercial backup, remote cabins and farms, hybrid solar + generator systems.

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
