Yes, the legality issue is one for each builder to confront personally. However, it is quite possible to design and build an isolated charger that is legal, efficient and reasonable cost. I have worked with a company here that is now producing a 5.4 kw charger programmable for Li and/or sla, can be powered from 3-phase or single phase mains with a PF of .99 and an efficiency of 92%. It can be set up for any output voltage in the range of 40 to 180 volts. I'm using one in my car to charge my 45 cell Li battery and it delivers 15A running from 230v single phase - I only have a 10A rated wall socket ie 2.3 kw input. Retail price is $US1995. It is isolated, legal and complies with all the regulations everywhere!
Sometimes I sits and thinks and sometimes I just sits.
