Xantrex Technology RS2000 manual Terminating the Equalization Process, Power Share

Operation

Terminating the Equalization Process

The equalization process can be terminated in three ways:

•user cancellation from the System Control Panel as shown in Figure 2-12

•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 RS2000 is 100 amps. You can reduce the total output if you change the “Charge Rate” setting on the RS2000 Advanced Menu or the maximum Power Share setting on the RS2000 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 RS2000 to charge your batteries even when incoming AC voltage is less than ideal.

Power Share

The RS2000 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 RS2000 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 RS2000 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 RS2000 will continue to supply the loads. The RS2000 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 RS2000 is to be avoided.
