At 400V battery voltage it will probably be "transformerless", in which case the power side would be capable of running at 200V for 120V output. The control would need to be "hacked". I have a UPS I bought for $300, 225V battery and 240V AC out. Not grid tied though, these are available 2nd hand, >From the weight I think it has a transformer and one purchased in USA would be 120V. This is wired to work with my Lexus 250H hybrid, leave the car running and the engine starts and stops as needed, giving mains power as long as there is petrol in the tank. I have not run it yet to check, but reports say efficiency is similar to running a Honda generator when it's needed.

Won't work with the 'battery' connection, but you could hook you truck battery to the PV input. In order to get the battery connection to work you'd have to hack the communications protocol between the inverter and the battery controller. What others have done is just hook their EV pack to the PV panel input, supposedly any DC input between about 120V and 550V should work. If you have it grid tied it will push the full 6kw to the grid. However, if it's functioning in island mode it will only pull enough power from the batteries to support the current load on the inverter. Again, this is what I've read online. I haven't tried it yet myself. _______________________________________________ Address messages to [email protected] No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/ LIST INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org _______________________________________________ Address messages to [email protected] No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/ LIST INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org
