Most people here are proud of their inverter/battery choices and want to know what the next guy chose...No. The vast majority of the system, case, wiring, inverter, batteries, etc are all USA made items.
I do appreciate that you are used to people using cheap electronics from China. If you knew me you would realize pretty fast that I am not going to do that.
Everything is brand name stuff, not cheap Chinese electronics.
I choose to not tell what brand the inverter is because it is very good, not because it is cheap. Trust me, it isn't. High end, made in US by a US owned firm.
If there is a US or North America (or EU) supplier with a rugged version of an offering, I will test it and try to design it in. My goal is to have a product with zero Chinese content but I have not yet succeeded.
The 120 vac charger we use is IOTA, which - while a US company, build them in China. I have tried to convince them to build some in the US and even offered to pay a premium but they wouldn't. I keep looking for a US version that will fit.
I did the engineering and design myself. Between me, one of my sons, and another part time helper, it is all assembled locally.
One of the three solar charge controllers is a german company brand made in China. The other 2 are US made.
The bulk of the system and wiring are designed for extended temperature operation, both on the high and low end.
As an example, the 10 awg wire inside is US made, mil spec, rated for (-55 C). We assemble this wire in house with panduit terminals and mil spec, adhesive lined heat shrink.
The heavier wire is US made, type S which is only rated for (-49 C), which is still much better than you will find in most any system out there. I don't have the equipment to properly terminate wire heavier than 10 awg, so I buy it with the lugs put on from a small US supplier in KY.
I'm doing some research on what people are installing in regards to power systems in vans. Would love to hear from people on what size and model inverter you are using and how many amp hours of battery power are installed. This is for a potential product I am working on... and just curiosity...
