The right inverter

Ive seen a list of best inverters and all, but all very pricy.
There is an inverter I see all over Truck stops:
PowerDrive 3000w pure sine - much cheaper

If they are used on big rigs, would it be enough to a skoolie?
Why the need for the $600-$900 inverter?

Planning to run a 3 to 400w solar, mostly all 12v equip if not all!

I am not knowledgeable enough about electronics to have my own opinion but from what I've heard from EE's, technicians, and knowledgeable tinkerers, is that when it comes to inverters, you (roughly) get what you pay for. The components needed to make a good solid inverter are not cheap, an inverter can be made cheaply but an inverter that (1) is durable and reliable, and (2) can handle 'inductive loads' and high surge currents (Such as A/C, some power tools, many motors) is not cheap to produce.


So, if your needs are modest, and you just want to power a few gadgets a cheaper inverter might be fine. But if you have power hungry appliances, inductive loads, etc, or want something that (1) should last 15+ years, and (2) can be repaired rather than replaced, a higher quality more robust inverter is the ticket.


Cheaper inverters also often inflate the power ratings, so be aware of that.

Reliability, longevity, output quality / accuracy

There's sine waves and sine waves.

If you were running $6000 of comms & navigation gear at sea, $1800 might be reasonable

Why a good name brand inverter?

Maybe we should ask the folks who's Ames inverter caught on fire? Or pretty much anyone who has tried to get support on a cheap Chinese inverter?

I'll stick with my Xantrex. Reliable, supported and repairable if they do fail.

Just my $0.02
