Deon Zeelie Posted March 13, 2019 Share Posted March 13, 2019 Can someone please clarify this contradicting statement. On the Voltronic Power page the indicate that the Axpert VN II can be connected without batteries running from either Grid or Solar. two installers I have spoken to says NO it cannot be done. According to them the only difference between the earlier one and this on is the PV input voltage that was increase to 450v. Quote Link to comment Share on other sites More sharing options...
GVC Posted March 13, 2019 Share Posted March 13, 2019 (edited) I have just read the brochure and both the 3KVA and 5KVA can run without batteries. • Inverter running without battery http://voltronicpower.com/content/download/Brochure/Axpert_VMII_DS.pdf Edited March 13, 2019 by GVC Youda 1 Quote Link to comment Share on other sites More sharing options...
SilverNodashi Posted March 13, 2019 Share Posted March 13, 2019 We don't get the Axpert MV II DS in South Africa, so their argument is based on the models we do get here. ___ 1 Quote Link to comment Share on other sites More sharing options...

I was unable to turn on my inverter without batteries. But i think that you only need batteries to turn it on. Once it is on you can disconnect it as i have heard but i have not tested it out for myselfe. Good luck. Quote Link to comment Share on other sites More sharing options...

It's more of an accidental side-effect, most probably not designed to work like that. Victron systems can also do this. There are enough large capacitors on the DC bus to keep things going if you disconnect the batteries... but it will usually drop out the second a large load starts or stops because the voltage will drop/spike out of range.
