Remark: Internal resistance is the important factor when working with low capacity batteries. Please consult your supplier or the relevant
sections of our book “electricity on board”, downloadable from our website.
Procedure
Proceed as follows to connect the battery cables:
Use an insulated box spanner in order to avoid shorting the battery.
Avoid shorting the battery cables.
Connect the battery cables: the + (red) and the - (black), to the battery see appendix A.
Reverse polarity connection (+ to – and – to +) will cause damage to the product.
Secure the nuts tightly in order to reduce the contact resistance as much as possible.
4.3 Connection of the AC cabling
This is a Safety Class I product (supplied with a protective grounding terminal).
The neutral wire of the AC output of this inverter is connected to the chassis (see appendix B for
1600VA/2000VA and appendix C for 3000VA/5000VA).
This is to ensure proper functioning of a GFCI (or RCCB) to be installed in the AC output of the Inverter.
The chassis of the product must be connected to ground, to the frame (of a vehicle) or the ground plate or
hull (of a boat).
Procedure
The terminal points are indicated clearly. From left to right: “L” (phase), “N” (neutral) and “PE” (earth).
4.4 Optional Connections
A number of optional connections are possible:
4.4.1 Remote on/off switch & remote Control panel
The product can be remotely controlled in three ways.
-
With a smart phone (iOS or Android) and the Victron Connect app.
-
With an external switch (connected to the two pole remote connector). Operates only if the switch on the Inverter is set to
“on”.
-
With a Phoenix Inverter Control VE.Direct panel (connected to the two pole remote connector; see appendix A). Operates only
if the switch on the inverter is set to “on”.
4.4.2. Programmable relay
The inverters are equipped with a multi-functional relay that by default is programmed in the normal operation mode. (VictronConnect
software needed to change relay functionality). The different relay modes can be summerized as follows:
-
Normal operation (“inverter” in VictronConnect app) – default
Relay closed during normal operation, and open when the inverter has switched off itself in alarm, has been switched off by a user and
also open (of course) when there is no power available on the terminals, ie. battery disconnected. In ECO mode, the relay will be closed
both when searching for a load and when fully on, ie. load detected.
Use this option when you want the relay to signal that there is power available on the output of the inverter.
-
Warnings and alarms (“alarm” in VictronConnect app)
Similar to above, but then the relay will also open when there is a warning. For example because the battery voltage dropped to the cut-
off value, or when loaded to the point where it will almost shut down due to overload. In ECO mode, the relay will be closed both when
searching (no load) and when fully on (load detected), except when there is a warning.
Use this option when you want the relay to signal that it is time to do something (charge the battery, reduce the load, and-so-forth), in
order to prevent a power outage.
-
Low battery (“Low battery” in VictronConnect app)
Relay on during normal operation. The relay will switch off once there is a low battery warning. It will remain off in case the inverter shuts
down due to low voltage, and will only switch back on again once the inverter is operational and the battery voltage is above the pre-
alarm reset level. Use this option for load shedding, or to automatically start a generator. Note that this can only be considered a poor-
mans generator start/stop. For more and better options, see here.
-
External fan (“fan” in VictronConnect app)
Relay is off, unless the fan inside the inverter is running. Use this option to switch an external fan, for situations when the inverter is in a
small enclosed space.
-
Disabled relay (“off” in VictronConnect app)
This option sets the relay in the OPEN position. Use this option if you do not plan to use the relay function.
