When the voltage goes below 47.2 the 2 minute start timer

five minute LBCO voltage timer starts. Because the 2 minute
timer will expire in 2 minutes and even if the warm-up time

generator start does not work properly if the batteries
reach LBCO before the 2 minute start timer fires the
generator with an external relay attached to one of the
inverters. The AGS settings are stored in the MATE3, so it
tries to tell the inverter to trigger the external relay
once the 2 minute voltage has been reached, but if LBCO has
been reached, the inverter will not supply voltage to the
coil.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 11pt; font-family:

set to 46.0V and the 2 minute start voltage set to 47.2V.
Under a very heavy load, it is completely plausible that the
LBCO could be met before the AGS via the inverter has time
to start the generator. The only “solution” is to have an
unacceptably high (IMHO) spread between the 2 minute start
and the LBCO.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 11pt; font-family:
"Calibri","sans-serif"; color: rgb(31,
73, 125);">In this case, I don’t want to set the LBCO too
low (i.e. default) because the system is unattended and if
the generator does not start for whatever reason, it is
reasonable to expect that the battery voltage could slowly
decrease to the LBCO and then stay there for a long period
of time until the problem is discovered. I want to keep the
LBCO relatively high, but I want the generator to reliably
start using start timers, SOC, or load. I think this is a
poor implementation of this feature, leading me to consider
a completely separate or auxiliary AGS system that is
voltage dependent without relying on the inverter relay to
start the generator.<o:p></o:p></span></p>
