Kilovault is newer to the market but is a division of the Alt E company who has a longstanding reputation for alternate energy here in the USA. Kilovault has an engineering team in Massachusetts that is continually improving the products. The latest release of the HLX+ is a prime example of that. Since they have a team here in North America, we are often in contact with them regarding system design and implementation. If an issue was to arise, they are quick to respond.
