We've been very happy with a pretty good collection of Victron equipment
. (Solar controllers, isolation transformers, inverter/chargers, battery
balancers) They have always worked as they should, and they have a huge number of options for control and monitoring of your power system. If you don't need it today, it will be there for the future. Their products play well together.
I can't give an opinion on their technical service
, because I have never needed it. Which I guess is as good a recommendation as you can get. Honestly, ever single
time I thought I might have a problem with a piece of Victron equipment
, it has turned out to be something else that was the cause.
