    Look at this one. Way overkill for your current set up but plenty of room for future expansion. I can't tell what output current will be, but the 24 volts can be boosted up

    Maybe if you wire 20 or so of these in parallel you might be able to get it to work ! LOL

    I would wire the necessary mean wells in series to get your 250 v once you establish a good stable output from the panels. Mean wells have isolated outputs

    These are I think from the same company that makes your boost converter: https://www.banggood.com/MPT-7210A-A...p-1056572.html

    I think they would be a good cheap, compact solar charge controller for a small dedicated PV set-up for charging a <72V EV battery system. I wonder if these could be put in series? Maybe 3 of them with separate panels charging 80V blocks of my 240V battery bank?

    I was thinking more along the lines of using a grid tie-in inverter, maybe a few in parallel to get the necessary power to drive the meanwells to 250 volt. Wont it be easier to boost 220 volt ac to 250 volt dc? Then the mean wells can be used to charge your 250 volt battery pack either on grid or off grid. http://www.ebay.com/itm/MPPT-1000W-G...r=461460113739

    Ive been using the BMS battery 600W charger going on 4 years and 4800 miles. Never had a problem. Charge to 90v @ 6 amps.
