Expanding a bit upon Ray's suggestion:<br>
For the DR series, which I believe was fundamentally an evolution of
its predecessor U-series, Trace wanted to see 164V AC peak under
load. This is because the charge function in the inverter grabbed
the peak of the AC waveform. Many cheaper generators could maintain
117 VAC RMS, but the peak voltage would drop under load as each
half-wave would flatten. This is why a generator could appear to be
supplying 117 VAC under load but the DC charge rate was anemic.
Also, this issue was addressed very successfully when the first
inverter-generators came out, as they maintained proper sinusoidal
waveform under load.<br>

can always add a boost transformer from Backwoods Solar, to boost
the VAC slightly (10%) to increase charge amps.
<br>
If you look at your peak voltage on that genny, its probably below
145 (should be 170 v peak for 120 v rms )

They were most sensitive to peak volts, not rms.

My 2512 manual shows 14.7 as high bulk and 16.1 for eq.
<br>
The 2624 should be double that.

Does anyone know of a link to the old Trace 2624
inverter/Charger (the one
<br>
with the plexiglass front. I believe the model number was
U2624, but I'm
<br>
not positive. I'm trying to remember what the maximum bulk
voltage
<br>
setting was on it. Also wondering how sensitive to lower
gennie voltage
<br>
output (113 vAC) the charger was. How much would that cut
down on the
<br>
current output capacity?
<br>
<br>
Thanks,
