Victron 2000 multiplus inverter

[NdaWind]

I just upgraded my Xantrex 458 inverter on my 2004 coach to a Victron 2000w multiplus inverter. On my Xantrex when I plugged into shore power or started the generator all electric plugs, microwave an TV would work along with air conditioners and frig. I only needed to turn on the inverter when I was not plugged in to shore power everything would work except A/C's and frig. Now with the Victron when I plug into shore power only A/C's and frig run I have to turn the Victron on to inverter to get the rest of the electrical system to work. Is the new Victron wired wrong or is there a setting?

If your drawing off the batteries when you switch on the inverter, it's wired wrong. Shore power should pass thru it.
Check your inverter breaker in the circuit breaker panel.

Using the Inverter or, when and why to use the Converter. Having owned different model RV's, my observation is that some have a stand-alone inverter and a separate, stand-alone converter/charger. Usually, the devices are from the same manufacturer and wired to a common distribution panel. Other unit's have a combined inverter and converter/charger. Everything in one box. Either way, the House Batteries are not going to deliver 120 Volt AC electricity to applances without running through the Inverter. And, if the Inverter has failed, which isn't that uncommon, it doesn't make any diference how good your house batteries are they aren't going to deliver AC power.


My existing Inverter is turned on when the Coach is in use but not plugged into Shore Power, or using the generator.
My Inverter is turned off when the Coach is not in use and not plugged into Shore Power. Left in long term storage, the inverter to be drawing 12 volt power and the batteries will drain. Even with no load on them.


Stand – alone Inverter:
Leave converter/charger "ON" all the time. It will actually only be working when plugged into shore power or using a generator.

Turn inverter "ON" when not using shore power or generator and you want to power a 120 volt device. Depending on which model and year Phoenix Cruiser, and considering possible wiring differences, those devices include the microwave, air conditioning, and hot water heater. The inverter changes 12 volts DC battery current to 120 volts AC and will maintain power for an abbreviated period.


Combined Inverter/Converter:
Inverters consumes 12 volt DC power when they are "ON". Some power is used to operate the inverter; some is used to produce 120 volt output. The more 120 volt power (watts) is used, the more 12 volt power is inverted.

Like the Stand-alone configuration, you only want the inverter "ON" when using 120 volt AC without shore power or generator because it consumes battery capacity.

You can leave the inverter "ON" when on shore power because shore power will replace what the inverter is consuming. However, the inverter is not usually needed when shore power is available.

You do not want the inverter to be drawing 12 volt power when the RV is in storage. Turn it "off" when storing or to save battery capacity.

The combined converter/charger function may not be obviously different from the combined inverter function. You want the converter function to be "ON" when connected to shore power or generator. So, even when the inverter function is "OFF", you’ll want the converter/charger function to stay "ON". Don't confuse the converter/charger function with the inverter function.

Check the Victron Support Site.

I have a Victron Multiplus II 3000VA inverter, but the 2000 version is different.

So many different options based on models and brands. Best to ask the manufacturer.

On my old coach it had a xantrex 458 before upgrading to Victron. It was wired so half the outlets only worked while on shore and the other half worked while on inverter. This was from a dual auto transfer switch.

With Victron it has a transfer switch built in. You should wire shore to the inverter then from inverter to outlets.

Victron has power assist and it needs to be turned on to pass thru the power to the outlets. It's a smart device and will passthru as much power as programmed then will use the inverter to assist and provide more power. So if you're on 30a you can pull 30a plus 2000w, so close to 5000w. It'll then charge the batteries when you're not using the power.
