This family-owned business has been at it since 1975! Being around that long means you have to be doing something right. Victron makes quality sine-wave inverters, inverter/chargers, charge controllers, DC-DC converters, and other renewable energy related electronics. They are based in The Netherlands, with a loyal following all over the globe, from the tropics to the (ant)arctic.
Victron has made a name for themselves for always being at the forefront of innovation. Many of their products now have Bluetooth capability, so you can control your system from you cellphone. Victron is particularly well-known in the world of campers, RVs, and boating. Less well-known is that they make great grid-tie products as well, and their inverters can be stacked in parallel as-needed very easily, to create a system of just about any size.
