an alternate opinion not shared by many others and damn few manufactures:
i personally do not like an integrated all in one unit, yes when they are working
they are a nice neat/pretty/well designed and functioning unit, but
when any single facet fails the whole unit has to go back for repairs or warranty.
most of us remember the days of the console entertainment center, the one with the television, turntable, radio all in one beatiful piece of furniture. if the amplifier went out, the thing was worthless and needed repairs before any of the functions worked properly.
after that rage, came the modular systems, where you had a tuner, a turn table, a preamp, an amplifier and seperate speakers, along with tape decks and all that
if anything quit you could simply remove that component and replace it an be back up
in no time while you waited for the unit to get back from repair or warrantee.
yes a modular approach is not as simple, and maybe not as clean, but
if you are going to be truely offgrid???
i know i do not want an inverter/charger/controller all in one unit in my offgrid
installation.
not when there are very good modular options that can be made to work together just as effectively, and in some cases more efficiently in my opinion.
thats my story and i am stickin with it
