hey,
I have 4 x 60w solarex panels probably around 10-12 years old maybe more.
I recently reconfigured to 24volt system and have 2 strings of 2panels.
today i checked with a MM what output was going into batteries(no reg,direct wire)
I checked it right at 12pm but it is tail end of winter here(australia, Sunshine Coast)
Anyways, I only read 5.7amps(24volt config) where as the panels (according to rating for powermax: on back) should be giving 7.5 amps configured for 24 volt. Is this normal?
I mean, I expect the ratings on back to be optimistic but is this a reasonable out put?
The wire run is about 10-12 metres using 4.58mm squared wire.
Is there a better way to test output than MM from + wire to battery + ?
