Hi
I have got me an old UPS PowerWare 9305 15KW and that is an 3 phase in and out with an internal battery pack there is 288Vdc
my idea is to add some extra batterys to it and then by using diodes for the extra pack it will be the UPS is changing the internal "small" battery pack and then solar panels are changing the external batterys, then there will be an extra control board there is disconnecting the AC input(via relays) when the battery pack is fully changed and when the battery gets down to some thing like 30% left then it connect the input line again.
I have the UPS with battery and all the AC stuff like relays, bypass panels, fusebox and so on.
so how can i smartest connect some solar panels to batterys with 288V ?
can i put MPPT controlles in series with diodes between them to get 288V ?
What do you guys think ?
What i dont have now is the solar panals and extra batterys.
Thanks
Thomas
