★ 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?
- Size the right power output. Inverters will be rated by a wattage value, telling you how many watts it can run at one time. For example, imagine you had a 500W fridge and 800W air conditioning. These two items would be 1300W and would require an inverter with a higher wattage than 1300W. (The calculation methods of variable frequency and fixed frequency are different.)
- Check your battery voltage. The DC voltage rating on the inverter will tell you what battery bank it is compatible with. For example, a 12V battery bank will require an inverter that is compatible with 12V DC input.
- Size your installation space. What area or space will you set your inverter? Make sure the inverter will fit in the space you have in mind with enough room around it for proper ventilation and no fire hazards.

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), maximum peak power (6000W / 10000W / 15000W), MPPT charging current (60A / 100A / 200A), and maximum PV array power input. The 10KW model also features dual MPPT inputs (2 x 5500W) and a larger physical size and weight (27kg vs. 11–12kg).
Q What battery types are compatible with this solar inverter?
This inverter supports Lithium batteries, Lead-acid batteries (including Sealed, AGM, Gel, and Flooded types), as well as a User Defined mode, all operating at a rated 48V DC with a voltage range of 40~60V.
Q What are the available charging modes on this inverter?
There are 4 charging modes available: Only Solar, Mains Priority, Solar Priority, and Mains & Solar off-grid charging. Additionally, the inverter supports 2 output modes: mains bypass and inverter output, giving you full flexibility for different energy scenarios.
Q Can multiple inverters be connected in parallel?
Yes. This inverter supports a parallel capacity of up to 9 units, allowing you to scale your off-grid power system to meet higher energy demands without replacing your existing equipment.
Q What communication interfaces does this inverter support?
