BB, two questions:
First: What about the panels (Kyoceras 130)?
Second: Isn't the MX60 supposed not to overcharge batteries?
[I cheked the battery bank, with a craftman volt meter, just minutes ago
(2:00 PM in Puerto Rico). Reading: 28.5 (Four 6 volt golf cart batteries, 24 volts nominal.)]

How accurate is the craftsman meter ?
Do you have a hydrometer & thermometer to measure charge with?
What has the water usage been in the batteries ? Do they need lots of water, do you hear lots of bubbles ? Can it possibly be in the middle of an EQ cycle?
Let battery bank charge for 2 days, no loads. 5 hours after sunset, and with 5 hours no loads, not using the battery for anything, the voltage read by your meter should be
** 25.4V ** at 77F If not, you battery is bad somewhere, or your meter needs to be calibrated. Meters do drift with age, and getting banged around.http://www.windsun.com/Batteries/Battery_FAQ.htm
Since the system is still "running" (I mean: PV panels are still on the roof, MX60 is on, batteries are been charged.), but without an inverter; Will all this cause any damage to any of those parts? The batteries are always on "float", (obviously: there is no load connected!)...I really need to know if I should turn off the MX60, or cover the panels, or disconnect the batteries.
It is 9:20 PM in Puerto Rico.... I turned off the DC breaker from the pvs. And this happened (or is happening):... Usually, at night, the main screen in the mx60 reads “PV voltage 09 V” (That’s when the mx60 is in “sleep” mode.). However, when I turned the breaker off, and cut off communication from the panels, that reading began to go up: 12…13…14…and up, until it stopped at 20 volts.
Is this normal? Is something wrong? Should I turn the breaker on again? [Note: I have not turned off the breaker between mx60 and batteries.]
