3kw Solar Panel Kits Commercial Rooftop Solar System For Homes

What’s in an off-grid solar system?

We assemble, wire, and test all the parts necessary to run your off-grid system right in our warehouse. Our designers are pros at building flexible systems that can be expanded if your energy needs change down the road.

3Kw Solar Panel Kit configuration:

	Solar panel： Simply put, panels absorb sunlight and convert it into electricity. We hand-select panels that are compatible with the batteries, power centers and other components packaged with your off-grid system. We double-check the math on voltage, amperage and string size to make sure you don’t damage your components. Where possible, we feature US-made panels with warranties that eclipse the industry standard. Your off-grid system runs 24/7, so your panels should be as reliable as possible. We’ve got you covered.
LiFePO4 lithium battery ： Batteries make off-grid solar possible. Without access to the utility grid, you need a reliable way to store the energy you generate for later use. Your battery bank keeps your appliances running — even at night or during winter, when the sun isn’t shining. It’s critical to build a battery bank that can store enough energy to get you through off-peak production periods. Our available battery banks come packaged with the capacity to get the job done.
	solar inverter： solar inverter is off-grid system with everything you need to get started: inverter, charge controller,and circuit breakers. We assemble in a one box  and test them on our workbench to make sure everything works the first time and every time. Once the solar inverter passes our internal tests, we label the final connection points for you to make installation as easy as possible.
Once you have the components, you’ll need to mount them in place. We offer several racking solutions to mount your system. Ground mounts can be aligned at the perfect angle to get the most output from your panels. Roof mounts are more cost-effective because they take advantage of your existing roof structure.

3KW  solar system load reference:

Remark: Refrigerator,air conditioner &water pump is inductive load ,start working power is 3-6 times more than normal power ,in the process of use ,turn on the inductive load first

How does the off grid solar power system work:

This system not only has solar power system function,but also has city grid complement function and UPS function
At daytime,the solar panels will generate the electricity to charge the battery bank through solar charge controller and the inverter will convert battery DC power into AC power and take the loads.
At nighttime,with fully charged battery bank,the inverter will convert battery DC power into AC power and take the loads
When there is no sunshine and battery power is used out,the inverter will automatically switch to use city grid power and take the loads

Advantage:

100%green energy，no pollution，no noise
High efficiency solar panel with 25 years lifespan can guarantee fast cost-recovery and long-term benefit
Stand-alone system,easy installation and operation
Nice after-sale service,provide installation guide and technical support
