. Auto Generator Start
The inverter can start up generator when battery voltage goes low.
When the inverter goes to low battery alarm, it can send a signal to start a generator and turn the
generator off after battery charging is finished.
The auto gen start feature will only work with generators which have automatic starting capability.
The generator must have start and stop controls [i.e., an electric starter and electric choke (for
gasoline units)], and the safety sensors to be able to start and stop automatically.
There is an open/close relay (constant open) that will close and short circuit the positive and neg-
ative cables from a generator start control. The input DC voltage can vary, but the max current
the relay can carry is 16 Amp.
The Auto Generator Start terminal pins are not polarized.
In addition, these two pins can also be used as dry contacts to send out “Low Battery Voltage”
signal to an external alarm device.
This AGS relay can also carry AC voltage within its capacity.
This inverter will skip the float charging when it is set at battery priority mode, so that the genera
-
tor will no longer be kept running to maintain a small charge on the batteries
Battery Temperature Sensing
Applying the proper charge voltage is critical for achieving optimum battery performance and lon-
gevity. The ideal charge voltage required by batteries changes with battery temperature.
The battery temperature sensor allows the charge controller to continuously adjust charge volt-
age based on actual battery temperature.
Temperature compensation of charge voltage assures that the battery receives the proper charge
voltage as battery temperature varies.
The entire line are equipped with Battery Temperature Sensing for increased charging precision.
It sends precise information to the charger, which automatically adjusts voltage to help ensure full
battery charge depending on the ambient temperature of your battery installation.
When the battery voltage is over 40ºC(104°F), it will reduce the charging voltage by 0.1Vdc with
every degree of temperature rise.
We recommend that you install Battery Temperature Sensors on all banks to protect your batter-
ies and to provide optimal charging of each bank.
The battery temperature sensor mounts on the side of a battery or any other location where the
precise temperature of battery can be detected such as battery mounting racks.
