    • Victron inverter is gold!!
Size: 12V 3000VA (UL)
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. ... show more

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 ... show more

    • Highly recommended for people who do not like problems (headaches)

Review Image by A. Tjahyadi
I started with Victron MultiPlus compact and I still have it running some critical loads in my house, running with Tesla batteries. I also have the phoenix inverter and it has been working great, especially with my tube amplifier (prone to HF noise). I never have any issue with their inverters, and they just work and it has been years. It is also working reliably when connected to other Victron inverter. This has been running non-stop with split phase, even when overloaded. It is a bit noisy when the ambient temperature is above 90F. However, I put them in the shed, so it is not a problem. Definitely on the higher side of the price, but they are worth every penny in my use case. I trust Victron as they have proven time and time again they are dependable. ... show more

    • Victron delivers
Size: 24V 3000VA (UL)
It's a Victron, it just works and works well. Classic case of getting what you pay for. It starts my camper ac unit that my 3000va generator won't with a 24v 100ah LiFePO4 battery.

    • Refreshing Old-School Quality
Size: 12V 3000VA (UL)
Victron is a class act, and well worth the price. Flexible, reliable, well designed, well built. This inverter/charger does what it claims with no issues. I won't repeat the features and specifications, as the documentation is accurate, complete and readily available. In a world of cheap products that are designed to sell but not to work, it's great to see real quality again. Highly recommended!! ... show more
