⭐ Product Advantages
1 3.5KW, 5.5KW, 10KW Off-grid Solar Inverter
Solar Off-grid Inverter is a new all-in-one off-grid solar charge inverter, which integrates solar energy storage & mains charging energy storage and AC sine wave output.
- Advanced SPWM technology output of pure sine wave.
- Optimized MPPT technology with an efficiency of 99.9%.
- Available in 4 charging modes.
- Designed with an LCD screen and 3 LED indicators for dynamic display.
2 Important Specification
Employed advanced SPWM technology and outputs pure sine wave to convert 48V DC to 90V–280V AC, 50Hz/60Hz frequency (Auto detection). Max PV open circuit voltage 100 Vdc; PV operating voltage range 30–100 Vdc; MPPT voltage range 120–450Vdc; Max 4000W input; Max 35000W output; Fit for 48V Lead-Acid (seal, AGM, Gel, Flooded) and Lithium battery.
3 Safe and Reliable
The power inverter has 360° all-round protection with a number of protection functions, including short circuit protection, over voltage and under voltage protection, overload protection, reverse protection, etc. Ideal for AC loads such as household appliances, power tools, industrial equipment, and electronic audio and video equipment.
4 Multiple Working Modes
4 charging modes — Only Solar, Mains Priority, Solar Priority and Mains & Solar off-grid charging; 2 output modes — mains bypass and inverter output. The inverter is designed with an LCD screen and 3 LED indicators for dynamic display of system data and operating status.
5 What Size Inverter Should I Buy?
- 1Size the right power output. Inverters are rated by wattage, indicating how many watts they can run at one time. For example, a 500W fridge and 800W air conditioner together require 1300W — so choose an inverter rated above 1300W. (Note: calculation methods differ for variable frequency vs. fixed frequency loads.)
- 2Check your battery voltage. The DC voltage rating on the inverter tells you what battery bank it is compatible with. For example, a 12V battery bank requires an inverter compatible with 12V DC input.
- 3Size your installation space. Ensure the inverter fits in your chosen space with adequate ventilation clearance and no fire hazards nearby.

Frequently Asked Questions
Q What is the difference between the 3.5KW, 5.5KW, and 10KW models?
The three models differ primarily in rated output power (3500W, 5500W, 10000W), peak power capacity, MPPT charging current (60A, 100A, 200A), max PV array input, bypass overload current, and physical dimensions and weight. The 10KW model also features dual MPPT inputs (2×5500W PV arrays) for greater solar harvesting flexibility.
Q What battery types are compatible with this inverter?
This inverter supports Lithium, Lead-acid (Sealed, AGM, Gel, Flooded), and User Defined battery types. The rated battery voltage is 48V DC with an operating range of 40–60V DC, making it compatible with most standard 48V battery bank configurations.
Q Can multiple inverters be connected in parallel?
Yes. These inverters support parallel connection with a maximum parallel capacity of 9 units, allowing you to significantly scale up your total output power to meet larger energy demands without replacing your existing units.
Q What protection features does this inverter include?
The inverter provides 360° all-round protection including: short circuit protection, over-voltage and under-voltage protection, overload protection (with tiered response: 102%–110% for 5 min, 110%–125% for 10s, >125% for 2s), reverse polarity protection, and charging short circuit protection via blown fuse.
Q What are the available charging and output modes?
There are 4 charging modes: Only Solar, Mains Priority, Solar Priority, and Mains & Solar combined off-grid charging. For output, there are 2 modes: mains bypass and inverter output. The system status is monitored via an LCD screen and 3 LED indicators for real-time display.
Q What communication interfaces and certifications does this inverter support?
The inverter includes RS485, CAN, USB, and Dry Contact embedded interfaces, with optional external WIFI/GPRS modules for remote monitoring. It holds CE safety certification (IEC62109-1) and EMC certification (EN61000), ensuring compliance with international standards.
