Zola Electric – formerly Off Grid Electric – is preparing to launch a new smart storage system targeting on-grid residential and commercial customers. The Infinity system has been in development for more than two years and was a major focus for funding from a $55m equity round completed in early 2018. The system is significantly larger than most solar home systems currently on the market, with 300W solar panels and 1.6-3kWh batteries, and includes features that mean it can play a very different role in power supply, leading Zola to call it an autonomous power grid rather than a solar home system.
