Info: The transfer to/from incoming AC occurs immediately when the Connect SOC or
Disconnect SOC setting is reached.
Info: A ME-BMK is required in order to use the 2E AC In – SOC setting. If this setting is
selected and there is no ME-BMK installed in the system, or if a valid SOC number is not
displayed under the METER/05 BMK Meters/05A SOC menu (i.e., Think’n , No Comm ,
Pwr-up Fault and Factory Fault are not valid SOC numbers), then the inverter will not
connect to the incoming AC power.
What is the AC In – SOC feature? This feature allows the inverter system to automatically
switch between utility connected and standalone battery operation based on the inverter’s battery
SOC that is provided by the ME-BMK battery monitor. When using this feature, the inverter loads
are normally powered from the battery and a solar array (or other energy source such as wind,
and/or hydro). In the event the solar array cannot deliver enough power and the battery’s SOC
drops to the Connect SOC setting, the inverter connects to the utility to continue powering the
loads connected to the inverter’s output and to charge the battery. Once the solar array can
again deliver enough power to charge the battery to the Disconnect SOC setting, the inverter
disconnects from the utility and again powers the inverter loads from the battery.
Where should I set AC In – SOC? Check with your battery manufacturer to determine the
correct settings for your batteries. For the Connect SOC setting, most manufacturers do not
recommend discharging the batteries below 50% to maintain the life of the battery. For the
Disconnect SOC setting, set it to a value to get at least an 80-85% charge (preferably 100%)
before the AC is disconnected and the inverter resumes powering from the batteries.
Info: When using AC In – SOC , ensure the SETUP: 03D Absorb Done SOC setting is
higher than the Disconnect SOC setting, or the inverter may not disconnect from the
incoming AC because the battery may not be charged to a high enough SOC level to
meet the Disconnect SOC setting.
1. The AC In –VDC and AC – In SOC features allow you to optimize the use of another energy
source (i.e., solar, wind, and/or hydro), and only allow the use of the utility power when the
energy source is not able to keep up with the load demands under normal conditions (e.g.,
cloudy day).
2. The energy source should be sized to meet the daily power requirements of the loads being
operated under normal conditions. Otherwise, the inverter would be connected to utility power
most of the time, resulting in excessive energy consumption from the utility.
3. The inverter system should not be con fi gured for use in a utility back-up scenario, otherwise
the battery may be in a highly discharged state when grid power goes down—preventing the
critical loads from running during a power outage.
4. The incoming AC is normally disconnected from the inverter. The Connect setting (VDC or
SOC) must be reached before the inverter allows the incoming AC to connect.
• 02F Inverter Always Power-Up When DC is Connected: Forces the inverter to turn on
when DC voltage to the inverter is applied. Allows the inverter to power up and provide AC
power automatically once the battery is connected to the inverter.
Default setting: NO
Range: YES, NO
What is the Always Power-Up feature? Normally, when DC power is connected to the inverter,
the user is required to press the inverter’s or the router’s power button to turn on the inverter.
If the Always Power-Up feature is activated by selecting “ YES ”, then whenever DC power is
connected, the inverter is automatically turned on and starts searching or inverting—depending
on the SETUP button’s 02 Inverter Setup/02A Search Watts setting. Once automatically turned
on, the power button on the inverter or router can be used to turn the inverter on or off.
Why use the Always Power-Up feature? Some people are familiar with Uninterruptable Power
Supplies (UPS) that power-up automatically when DC power is connected. The Always Power-Up
feature allows the inverter to power-on similar to an UPS.
