Victron isn't exactly a bargain basement supplier, the people that buy their stuff depend on it for their lives. Their quality control, spares supplies and longevity are second to none, that goes for chargers, inverters and battery systems. If you're not worried about having power, having your inverter fail when you need it most, have your batteries in an outdoor enclosure of their own then you can skimp on all of this, probably cheapest option would then be to use reclaimed batteries and some cheap Chinese sine wave (for some definition of sine wave, most of them are 4 bit modified square wave that are run through a large transformer to smooth out the curve) inverter. That way you get a lot of bang for your buck, and even if the inverter ever dies you can just get a new one.

But when you are putting together a system that simply needs to work and that outputs clean power then you have very few companies that are that well supported. I've used Xantrex, Sunpower, Victron, ABB and a bunch of noname stuff. I'm sure there are plenty of others. The only one that comes close in design quality is ABB, Xantrex used to be good but it has gone down tremendously in the last decade and a half, the remainder I will never use again.
