Terminating the Equalization Process
The equalization process can be terminated in three ways:
• user cancellation from the System Control Panel as shown in Figure 2-15
• inverter/charger cancellation if AC is removed or the charger is disabled
• successful completion of the equalization process
Operating Limits for Charger Operation
The maximum output current for the MS2000 is 100 amps, split between the main
charger (maximum 100 amps DC) and the Echo Charger (maximum 10 amps
DC). You can reduce the total output if you change the “Charge Rate” setting on
the MS2000 Advanced Menu or the maximum Power Share setting on the
MS2000 Basic Menu.
The charger can operate over an AC input range of 90–135 volts AC. This is the
default setting and can be adjusted to 85–145 volts AC as a maximum range and
to 110–120 volts AC as a minimum range.This wide range allows the MS2000 to
charge your batteries even when incoming AC voltage is less than ideal.
Power Share
The MS2000 charger shares incoming power with AC loads. The AC loads have
priority, which means that the charger will reduce its output with large AC loads
and increase the output again when the AC load decreases. The regulatory
maximum for continuous AC loads is 80% of the breaker rating that the loads are
connected to.
The MS2000 senses pass-through current going to the AC load. The difference
between the pass-through (load) and 80% of the Power Share setting is the current
that is available for charging the batteries.
For example, if the AC input of the MS2000 is from an AC panel with a 30A
breaker, the Power Share setting on the System Control Panel should be selected
as 30A. Based on this, the charger will control the charge current so that the total
current draw is equal to or less than 24A in this case. Should the load current be
more than 24A, the charger output will reduce to 0A, but the MS2000 will
continue to supply the loads. The MS2000 will continue to pass-through power to
the loads, even if the load current exceeds the Power Share setting. In this case, it
will be up to the user to remove/disconnect loads if tripping the AC input breaker
supplying the MS2000 is to be avoided.
Important: Changing the “Charge Rate” setting does not affect the Echo Charger’s
output current.
