There are 2-3 ways to go about your project.
First, do it on the cheap and purchase used parts where you can like panels and inverters, maybe even batteries.
Second, buy new products, but not the highest quality and not CSA or UL listed. This route often provides equipment of a lower quality and performance. It may work well or not and may present more of a fire risk or lower performance as well as less support from the manufacturer or seller. It will add less value.
Third, purchase first rate hardware that is CSA/UL listed. This will cost more, but not much more if you shop around. performance and support will be available and met. Duration will be the longest, fire risk the lowest and value added to your property the most. Worry when you are not the very low. Many of these solution allow remote control via wifi or cellular.
Now, question: Are you off grid in a place like Markham, ON or like Nunavut?
So what is the winter climate and summer climate, power needs in amps drawn by all connected devices and critical devices. Say the postal code would help location.
The best thing to do is to plan carefully. Write down what your performance expectations for your project are to be.
Write down your budget. Calculate your loads. Calculate your potential return on investment either by not having a diesel generator and fuel as primary power source. Know your expectations. Also figure out upon your expected or unexpected death, who will assume responsibility for the care, operation and maintenance of the system.
If you do this all first, rather than just buy a kit you saw online, you will get a much better final result.
Lastly, inverters are basically high frequency and low frequency. The low frequency use transformers to produce the output voltages, the high frequency models use high frequency electronic parts to produce the voltages. Low frequency inverters are old school, but run loads with larger inductive currents, like starting a motor would pose (blower motor, saw motor, etc.). This might be important to you in that off grid location.
So do some homework and lets follow up.
