48V 11KW Off Grid Solar Inverter Support LiFePO4 Battery RS485 Communication Parallel Connection

Overview

Our 11KVA off-grid solar inverter is a high-performance hybrid solar power inverter designed for standalone off-grid solar energy storage systems. Integrated with dual MPPT solar charge controllers, pure sine wave AC output, parallel expansion capability and full battery protection functions, this 11000W off-grid inverter perfectly matches 48V lithium iron phosphate batteries and lead-acid batteries. It can work normally without a battery connected, supports dual AC output and multiple output priority modes, ideal for residential backup power, remote off-grid areas, farms and commercial independent power supply projects. With IP21 ingress protection, wide operating temperature range and optional WiFi remote monitoring, it delivers stable, reliable and efficient off-grid solar power conversion for global users.

• High Efficiency & Pure Power: Achieves up to 96% peak efficiency (PV to AC) and delivers pure sine wave output (230VAC), ensuring safe and optimal operation for all sensitive electronics and appliances.
• Advanced Dual Solar Charging: Built-in dual MPPT controllers (Max 160A) allow connection of two separate PV arrays, maximizing solar energy harvest from different roof angles or panel types.
• Flexible Power Modes: Operates with or without a battery. Features dual AC outputs (Main: 11KW, Secondary: 5.5KW) for intelligent load management and critical circuit backup.
• Scalable System Design: Supports parallel connection of up to 6 units, enabling power expansion up to 66KW to meet growing energy demands.
• Smart Monitoring & Communication: Built-in WiFi for remote monitoring and control. Compatible with lithium batteries via RS485 communication for optimal battery management (BMS).
• Robust & Reliable: Rated IP21 for dust and drip protection. Wide operating temperature range (-10°C to 55°C) and a durable metal casing ensure performance in diverse environments.
• User-Friendly Design: Clear LCD display, intuitive controls, and well-labeled connection ports (AC IN, AC OUT, PV IN, Parallel Ports) simplify installation and operation.

• Residential: Whole-house or critical load backup power, maximizing self-consumption of solar energy, reducing electricity bills.
• Commercial: Powering small businesses, offices, workshops, or remote telecom sites with reliable off-grid or backup power.
• Hybrid Systems: Ideal for solar-plus-storage systems aiming for energy independence and grid resilience.
