It’s victron
Size: 12V 3000VA
It’s victron what else to say. But a few comments it’s heavy so mount it on a sturdy surface. Connecting it is easy with the push connectors. Programming isn’t terrible just watch some you tube videos and that’s it your off and running to power your house cabin rv etc Is it worth th money ……if you want quality and interface with other victron components yes it’s worth every penny. Are there other cheaper options, probably but I have a full victron sytem so I didnt really look

Victron inverter is gold!!
Size: 12V 3000VA
Wanted to replace our 10 year old inverter charger after upgrading 400ah batteries to lithium in our motorhome. Spent 3 months trying to resolve multiple issues with an eco-worthy 3000w inverter charger. Issues were never diagnosed and never fixed. So I returned the defective eco-worthy products (yes, two of them did not work). Then, I bought the victron 3000w inverter charger. Installed in 1 hour. It worked perfectly, no issues, no problems!! I now see why victron is the gold standard for lithium capable inverter chargers. Highly recommended.

Faulty Unit. Do not buy used inverters from Inverters-R-Us
Size: 12V 3000VA
Bought a "Used - Mint" MultiPlus-II 12/120/3000 from Inverters-R-Us and just started it up for the very first time last week and it's a faulty unit. Inverter has an internal short most likely as it Immediately goes into overload upon start up with NO loads connected. There is no way to contact the seller on Amazon and the return window is gone. I purchased all items for my build in June and it took a few months to build the van out and get the house battery system installed. I should have tested it when it arrived as it's just been in its box all Summer waiting to be installed. Now I have a $900 paper weight. Do not buy used products from this company buy the new version from a different reputable seller.
