Felicity Solar 12kW 48V Off-Grid Inverter

Felicity Solar 12kW 48V Off-Grid Inverter – High-Power 12kW Solar Inverter for Battery-Based Systems

Felicity Solar 12kW 48V Off-Grid Inverter Overview

The Felicity Solar 12kW 48V off-grid inverter (IVEM12048-Ⅱ) is a powerful single-phase solar inverter designed for battery-centric energy systems where reliability, high solar input, and stable power delivery are critical. This 12kW solar inverter is ideal for residential homes, farms, workshops, offices, and small commercial environments that require dependable off-grid or backup power solutions. Built to operate with a 48V battery bank, the Felicity Solar 12kW off-grid inverter converts solar energy and stored battery power into clean, stable 230VAC pure sine wave electricity, ensuring uninterrupted power for both sensitive electronics and high-load appliances.

12kW Pure Sine Wave Output for Reliable Power

The Felicity Solar 12kW 48V inverter delivers a true pure sine wave output at 230VAC single-phase, making it fully compatible with all household and commercial appliances. From sensitive electronics such as computers, televisions, and networking equipment to high-power loads like refrigerators, pumps, air conditioners, and power tools, this 12kW off-grid inverter ensures smooth, noise-free, and stable operation. Pure sine wave technology also helps extend appliance lifespan and prevents electrical noise, overheating, or erratic behaviour commonly associated with modified sine wave systems.

High-Efficiency Operation with Advanced Power Electronics

Designed for performance and efficiency, the Felicity Solar 12kW off-grid inverter operates at an efficiency of ≥94%, reducing energy losses during DC-to-AC conversion. This high efficiency allows more usable energy from both solar panels and batteries, improving overall system performance and reducing long-term energy costs.

Dual MPPT Solar Input for Maximum Energy Harvest

The Felicity Solar 12kW 48V off-grid inverter features two independent MPPT solar charge controllers, each capable of handling up to 8000W of solar input. This provides a combined maximum PV input capacity of 16kW, allowing generous solar panel oversizing to maximise energy production throughout the day. With an MPPT voltage range of 120V to 500V and a maximum MPPT current of 160A per tracker, this 12kW solar inverter supports flexible string configurations, long panel strings, and improved performance during cloudy or partially shaded conditions.

48V Battery System with High Charging Capability

The Felicity Solar 12kW off-grid inverter is designed to operate with a 48V battery bank and supports both lithium and lead-acid battery technologies. The integrated AC charger is configurable up to 160A, enabling fast and efficient battery charging from grid power or generator input when solar energy is insufficient. This makes the Felicity Solar 12kW inverter well suited for large battery banks, extended backup runtime, and demanding load-shedding or off-grid environments.

Battery-First Off-Grid Architecture

Unlike grid-tie hybrid inverters, the Felicity Solar 12kW 48V off-grid inverter is built around a battery-first design. The inverter prioritises battery and solar energy to supply loads, with grid or generator input used only as a backup charging source when required. This architecture makes the inverter ideal for off-grid installations, semi-off-grid homes, and backup power systems where grid feedback or export is not required.

User-Friendly LCD Display & System Monitoring

The built-in LCD display on the Felicity Solar 12kW off-grid inverter provides real-time system information including battery status, solar input, load consumption, charging mode, and fault alerts. This allows users and installers to easily monitor system performance and make adjustments when needed.

Comprehensive Safety & Protection Features

The Felicity Solar 12kW 48V inverter includes multiple layers of protection to ensure system safety and long-term reliability. Protection features include overload protection, short-circuit protection, over-temperature shutdown, low battery protection, reverse polarity protection, and overcharge safeguards. These built-in protections help protect the inverter, battery bank, and connected appliances from electrical faults and abnormal operating conditions.

Installation, Build Quality & Operating Environment

The Felicity Solar 12kW off-grid inverter is designed for wall-mounted installation and features a robust metal enclosure suitable for indoor installation in garages, plant rooms, utility rooms, and dedicated inverter spaces. With an operating temperature range of 0°C to 55°C, the inverter is well suited for a wide range of residential and commercial environments. The compact design and solid construction ensure reliable operation and ease of installation in both new and existing solar power systems.
