36 volts is an odd duck. I can not look things up for I am at home and do not want to use up my neighbors generosity in bandwidth. Outback may have a charger that could be set at 36 volts, but I a fairly certain the inverters won't do. I could be pleasantly surprised. You may need to look at a specialty place like Atkinsons. I am unsure if they have anything, but they do engineer things like 3-wire starters for generators.
