A google of the model number you list up there has as it's first result a manual that describes it's functions
http://files.sma.de/dl/5673/SB2500-11-EE4801.pdf
and searching that document for MPP finds it in several pages, that should answer your question about how it works.

thanks for the info. i swear my google is playing up :)

the clowns who installed my solar setup for my dad installed the expansion tank upside down for the solar water heater section....and i havn't even started looking at how poorly theyve set up the controllers setting for the solar.

ill have a good read of the manual and see whats what....then ill probably have a million more questions :P

thanks again

looks like i cant change much in the settings to get any more out of them :(

however my inverter does stop producing when the panels voltage is less than 85V. leaving a few hours at the start and end of each day where the panels are producing but not enough for the sunny boy. and possibly a lot more hours in the winter months.

meaning to get that extra power id need an invertor that worked at a much lower input voltage.
and then figure out a way for it to automatically switch between the two.

any ideas?
