Michael, in my experience laptop power units are DC as in they take ac power and convert it to DC to run the laptop. Usually those types of power units are ok with modified sine wave. You will get in trouble if you try to charge up most cordless tools though.

I was able to achieve this year the purchase of 10 x 100 watt solar panels for what looks like its going to be an off-grid tiny house. The controller I have came with a 200 watt kit its kind of dinky and I am sure is not up to the job so that will need to be replaced. As for converters I bought this: YSOLX 1000 watt converter. I suspect I did badly. I have a desktop that is my workstation and entertainment center . I can cook with fire and heat water with sun, but Im NOT parting with the laptop. Yet the converter is a "modified sine wave" type. Will my computer and monitor work with this device?
As for batteries Im just going with local Walmart golf cart batteries. No muss no fuss.
The converter issue is troubling me however. Any thoughts?
PS thats a typo below..it should read "1000" instead of "100".
maximum power point tracking...

200W Solar Array (over sized to 1000W)
200W Charge Controller
800W Inverter (oversized to 1000W)
3,200WH Battery Bank
800WH Daily Load
Daily Usage = Daily Production = 4x Solar Array = 4x ChargeController = Inverter = BatteryBank/4 = Peak Load
800WH = 800WH(200W x 4H) = 4x 200W = 4x 200W(12V*16.8A) = 800W = 3,200WH/4
