Victron for off grid use


Recommended Posts

I been back and forth with different inverters. Concerning Victron, I would get the 48/8000 230v with an autotransformer. Would like to set up where solar and batteries running coach. Use only utility when batteries low. So can it be setup this way? All the others I research stress this fact. Victron only seems to provide backup power. It seems it could be setup to but not read that

I was off from work today so had time to study. Working 12 hr days and no time for much less. so it is to be set up in "island mode". Sure looks like Victron would make things simpler. They are arguably the best but lacks big time in instructions for the masses. All the others, even the cheap Growatt is simple instructions. This fact is what has always put a bad taste in Victron. Seems one can even sell back to grid but not certified in USA. Have to give this some thought.  Some Schneider installers have given up on them and went to other brands so I looking elsewhere. Also that 48/8000 is 6000 watts. 8000VA. So no more than the Growatt two 3000w. And it is simple. Most our high power uses be based on watts not VA. Hot water, electric cooking.

Looking at the multi plus 2. They are the 230v/240v units depending on 50 or 60 hz. I can get them in 48v/5000 which will give me 4000 watts. Parrell will be 8000 watts. Can get them $1600ish each. The quattro 48/8000 is only 6000 watts and close to same price. Which I think we be safe with 6k watts though but a little cushion not bad either. Also they will pull from second unit as needed so should be more efficient. Will have to use an autotransformer but that is a plus anyway.

Glen, the Growatt inverter is also rated in VA as well as watts. They are the same number which means they are calculating the watts using a purely resistive load.

Victron's are rated in VA and the reduced Wattage rating is due to them using a power factor to give you a more realistic number. VA are VA but watts are not watts unless you know how they calculated them in an AC power system
