Victron Blue Smart 12/30, 3 outlets, Can I power this via an Inverter and what size is needed, ?????

[Boysan]

Just got the above Victron unit today, looks to be a nicely made item and easy enough to fit....
I was wondering if it is at all possible to use this via an Inverter....????
As although it is now wired in directly to the 240 "on site" hook up,via a 240v socket and the original Victron 3 pin plug..... am I right in thinking that if when not on site if I could utilise it to charge up a couple of extra leisure batteries we have.... as although I do have a split relay charging system in situ as well.... with the Victron it would be able to charge the batteries up a lot lot faster I would of thought... plus I wouldn't have to be driving about just to charge up the batteries...(and yes I should of had the dc to dc system installed but thats another story all together.)...

So if I can use an inverter... what size would be suitable to use to do the job.... ????? the idea being that I could run a seperate set of 12 volt cables from the main starter battery to the inverter, turn over the engine, and then just plug the Victron into the Inverter... thus charging at 30 amps.... or am I a complete numpty for thinking this way....

Thanks in advance... Boysan...

What battery do you intend to use to power said inverter?

i think hes wants to power it from the "running engine". . . . and starter battery.

the idea being that I could run a seperate set of 12 volt cables from the main starter battery to the inverter, turn over the engine, and then just plug the Victron into the Inverter... thus charging at 30 amps.... or am I a complete numpty for thinking this way.

so using the diesel engine to create the 12v for the starter - that the inverter will be running from to create 240v - that will power the 240v mains charger - that will create the 12v to charge the new batterys . . .

now I've types it all out . . . its all possible but maybe a bit lossy?

might be more efficient to just fit a DC-DC charger . . (swap out the SCR) - then connect the new extra batteries to the existing LB - then run the engine.

@Boysan what victron charger is it?

the IP22 charger comes in 15/20/30A ?

what Amp rating? - that will tell you what size inverter you need

 

[Dellmassive]

rough guess . . . .

w= v*a

15a*12v = 180w +10% = 198w
20a*12v = 240w +10% = 264w
30a*12v = 360w +10% = 396w

 

[Dellmassive]

a general rule is to double the load rating for the inverter size (based in a pure sine wave inverter - dont bother with a MSW)


15a*12v = 180w +10% = 198w - round up to 200w then double = 400w inverter needed

20a*12v = 240w +10% = 264w - round up to 300w then double = 600w inverter needed

30a*12v = 360w +10% = 396w - round up to 400w then double = 800w inverter needed

Just put an Orion 12/30 in there & forget the inverter. It will also make a better job of charging your existing leisure battery.

I have a spare 110 amp Leisure Battery that I built into a battery box with the various "take offs" but I did wonder as to if it would be beffy enough to run a inverter for enough time to charge up 2 other leisure batteries via the Victron, br Boysan...

Hi, Its the Victron 12/30 with 3 outputs... and the overall idea was that there would be a spare port on the Victron so why not utilise it in some way... as most of the camping we do tends to be wildcamping... and although I already have a couple of batteries linked as a single battery bank... when the mrs decides that she wants to use nigh on every 12v outlet that there is in the van then they soon drop...and also I am a bit of a stickler for not letting batteries drop to low anyway.... but then again I think if I was to drag a trailer with 20 batteries in it the mrs would drain them, one way or another....lol...br Boysan...

Dellmassive.... thanks for going to the effort of listing the above.... all noted and it looks like the 800 watt version is what I would require as a minimum just for this job.... I was looking at getting the same make as the charger Victron... as they do seem to be well made items... and have been looking at the 1200 watt version they do.... unless you have some other brand that you would be able to recommend....????? cheers... Boysan..

The 800va victron is very good. And will surge above 1200va.

The do a 1200va also...

They are large and heavy duty..


Aside from that look at the Renogy and Cotek ranges.. (pure sine)

Sadly too late to be doing anything like that.... as the victron 12/30 is already in now... but thanks anyway for the advice... maybe in the next one eh... br Boysan...

Cheers for that, I just can't get over how fast the replies are on this forum... super service.... I will have a look at the makes you mention.... and report back.... if its something I can just tuck away until needed then the weight isn't an issue... but on reflection if its a big box of tricks... then I will have to see...as space is a premium with these vans... as I am sure you will agree... but again thanks for the reply... cheers...
