help with TRACE M2512 inverter Charger.

[Ray Harkins]

Hello everyone. This is Ray in Fresno,Ca. I have a  Trace M2512 installed in my houseboat. I upgraded the remote controller to a RC-7. Programed it up for use with my S-650 wet batteries. Yesterday I tried to equalize the batteries. The remote went into equalize and the yellow light flashed rapidly as per the manual. After the second hour  I went back and checked the battery voltage. It was 13.5 volts. The manual says it should be at 15.2 to 15.5 volts. Any idea what I should check or do to get the voltage up. THANK YOU......Ray  KB6LQV

hi ray,
i'll take a guess at it being you did not state what mode it was in when you checked on it. before i do, do realize this is midnite solar's website and not schneider electric, but i'm sure the guys here don't so much mind. my guess might be that it exited eq and went to float as i believe 13.5v is about the float voltage for those batteries. eq charges are limited and i can't say how long it should've been on for on your equipment. if you still need a higher specific gravity then eq it again. if you have a dmm then verify that the voltage was being raised to the desired eq voltage.

Maybe it was current limited ?

That would keep the voltage from rising.

Low grid voltage can keep those kinds of chargers from getting
the  battery voltage high enough if it is working at all.

Could also be a bad part of the circuit that tells the micro what the
battery voltage is.  Is the system  battery temperature compensated ?
High temp will lower the voltage but I can't remember if the M1512
temp comps the EQ charge or not.

I agree with all of the above. Start an EQ and watch the battery voltage rise with a digital voltmeter. I do not remember if there are many adhustments like for time? Make sure the EQ voltage is set high though.
