Inverter Charger Split Phase Programming

April 30, 2024

Inverter chargers are an instrumental part of an off-grid electrical system. Combining the function of an inverter, battery charger, and transfer switch into a single unit allows DC power from batteries to be converted into AC power for household appliances. Depending on what your system is powering, two types of inverter chargers are available. While a single-phase inverter charger is perfect for those looking to power essential household appliances, a split-phase inverter charger is necessary for large applications requiring 240V power, such as refrigerators and compressors.

How to Program Victron Inverter Charger for Split Phase

To utilize the split phase function, you must program your Victron Energy inverter charger appropriately. Let’s walk through the steps together. First, go to victronenergy.com and select the downloads tab in the top right corner of the webpage. From here, scroll down until you see “VE Configuration Tools”. Download all files.

Next, locate the VE.Download the direct USB driver for VictronConnect and install it on your laptop. Victron Inverter Charger intro settings for split phase programming

Once the downloads are complete, open up the VE.Bus Quick Configure on a laptop. When prompted to choose an action, select “Setup a Ve.Bus system.” Victron Inverter Charger for connections for split phase programming

Then, for setup configuration, select “Split phase 180 degrees.” Victron Inverter Charger for connections for split phase programming

Before continuing, connect all Multis and the MK2/3 through the RJ45 connector and other supplied cables. DO NOT USE A SPLITTER BOX. Victron Inverter Charger for connections for split phase programming

Then, connect the MK2/3 to your laptop. Com 3 is the most common comport used for this application. Ensure the corresponding comport is selected in the next step. Victron Inverter Charger for connections for split phase programming

IMPORTANT: Before continuing, ensure that ALL devices, including the remote panel, are switched to OFF! Victron Inverter Charger primary and secondary split phase programming

Once your settings match the above photos, select “Send settings” in the lower left-hand corner. Make sure you send all settings to ALL devices. Then, open up VE.System Configurator. Victron Inverter Charger final settings for split phase programming

IMPORTANT: ONCE YOU OPEN THE CONFIGURATOR, SELECT THE “CONFIGURE” TAB AT THE TOP AND SELECT A COMPORT TO CONNECT THE INVERTERS. IT SHOULD LOOK LIKE THE PHOTO BELOW> NOTE: YOU MAY HAVE AC INPUT 1 AND 2, WHICH IS OK. Victron Inverter Charger final settings for split phase programming

Next, uncheck “switch as group.” Once you have done this, go to the “Configure” tab and select “Send configuration.” Victron Inverter Charger final settings for split phase programming

Once this has been done, you can exit the application. Your Inverter charger is now properly programmed for split phase.
