Victron Inverter

[nfm21962]

I have a Victron Inverter with 2 lithium batteries plus a solar panel . Left S. Dakota sunday heading home to RI . So this morning was our 2 nd morning without being hooked up to power . Started generator this am for coffe . 15 minutes later it shuts down wouldn't restart and all on inverter power was off . Isnt this suppose to charge itself and batteries when driving ?

What's your fuel level? In the morning, batteries will be at their lowest charge state.

If you have a Victron inverter/charger, it should charge the batteries while the generator is running.

If set up that way, it should also charge the batteries with the engine alternator thru the chassis batteries.

What inverter do you have, and is charging enabled.

Should I assume the problem is entirely due to discharged house battery bank?

Yes, most RV's charge from the engine alternator through a bridge circuit connected to the chassis battery. A failed bridge circuit can stop that.

A solar panel may charge the battery bank while driving. How much charge depends on the make and model of solar panel, solar controller, and the weather.

Is the solar controller connected to the chassis battery or the house battery? What is the capacity of the solar system?

There are many possible reasons for discharged house batteries after two days of driving.

Entry door 12 volt house battery disconnect is turned "OFF" while driving.
Battery disconnect near the battery is "OFF" while driving.
Bridge circuit to the chassis battery is defective.
Loose or corroded connection in the bridge circuit.
Defective battery. One shorted cell in the battery bank can pull the whole bank down.

Normally an RV generator will not shut down in 15 minutes. It should continue running until you shut it down. On the other hand you may have programmable auto generator start and shut down. Do you know why the generator shut down?

It should of course start on demand. Why didn't it start? Did the starter turn when you tried to start? Did you try using the "boost" button to connect the chassis battery to start?

Generator may require 12 volts from RV for controls. Dead batteries and Victron not charging or converting could cause the generator to stop. Is the Victron charger turned "off".

Loose or corroded connections of course can cause all of this.

Post generator make and model # for better advice.

Low fuel? From his profile, he has a Thor Outlaw 38MB. Current standard spec's include "Onan® RV QG 5500 Gas Generator" and "Four (4) Auxiliary House Batteries". No mention of a lithium option. Standard solar is 100 watts and an additional 400 watts option. Also standard is a residential fridge.

My guess would be both the fuel tank and house battery bank got too low. Usually the fuel tap is between 1/4 and 1/2 tank. No idea why the coach wasn't charging the house unless that was disconnected when the lithium was added or possibly a failed L-BIM.

Talked to the maker of the inverter today . Only charges off the generator or when plugged into shore power . Not setvup to power off alrernator . Everything seems to be working fine today except for generator started right up starting running fine then started surging and shut down never had problem with it in the past always ran fine

Alternator charging is a seperate system and part of the RV. Has nothing to do with the inverter/charger or shore power/generator..

Inverter is fine figured it out . Generator is the issue . Tried it today started up ran for a short time less than 5 minutes thenshut down would not restart . Im calling onan in am .
