[RE-wrenches] XW6048 parts problem

[Ezra Auerbach]

Hi Folks,

I had an XW on my off grid system for a number of months, at the  
insistence of my partner it has been taken out and our old SW Plus is  
back doing homestead power duty. The reason we took the XW out of  
service was because it had an unreasonably high tare loss and it  
didn't work well with our 3 kW Honda generators - it kept dropping it  
off charge. I really liked the user interface but only with the  
addition of the Remote Panel, the machine itself without the remote  
would be a pain to operate. It was no surprise to learn that they  
were made in China, but I tend to agree that small parts should be  
available for this sort of product.


Best regards,

Ezra
