Getting stuck without power is not ideal. The good news is there are plenty of home backup systems that can keep your fridge, WiFi, and other devices going. The Sierro home backup system is one of the smallest ones we have seen. It doesn’t require a complex installation. You can fit this anywhere and keep your devices going for up to 3 days. It has a noise rating of 25dB, so it won’t disturb you.
Sierro 2000 has a footprint of up to 16 x 19.7 x 4.3 inches. It has enough capacity to keep a deep freezer going for 40 hours. It has an auto-switch UPS function to switch under 15ms for seamless transfer. Sierro supports car charging and solar input up to 550w. With app connectivity, you can monitor battery and keep up with outage alerts. You can get this in two capacities (1kWh & 2kWh). The larger model weighs only 44lbs. You can find this project on Kickstarter.
