mine is old, but they are still in production
and available
i have a Turnigy Power "watt meter"
gives me voltage , amps, watt Hrs, amp hrs,
live in the moment reading and accumulated totals, and peak amps reached and peak watts reached
every day i LOG the days readings using a daily planner as the log book
and then reset the meter
example yesterday i did a solar test
the total solar harvest, was 2028.7 wattHrs and 148.13 amp hrs
this actually a bit low for a 505w system, but the panels are flat and not tracking the sun, yesterday was HOT..and heat reduces output
also there is a lot of wire in my system, and the panels are in parallel not high voltage series
morning star have some very nice controllers
