The Explorer 5000 Plus is bought to back up a house, not a fridge. An owner wired it in through an interlock and 50A inlet and runs every 120V circuit for almost ten hours, and another with two units, eight packs and a transfer switch came through an 80-hour outage. A couple living in a converted bus use it daily and say it has never failed at a critical time.
Firmware and the STS draw the complaints: one system ignores its reserve and charge limits, schedules cannot cross midnight, AC output has cut out on several firmware versions, and one owner's STS stopped charging after another Jackery was added to the app. One owner who had to ask support for 1.4 saw 1.92 pushed out in February 2026. Solar is a strength, with MC4 high-voltage input and 8mm low-voltage ports. Car charging is a curiosity: an owner measured about 103W, 55 hours from 14%. At 134.5 lbs it stays where it is installed, which needs to be indoors or insulated given its IP20 rating and cold-weather pause.
A growth path to 60kWh of 240V backup is the draw. One shopper weighed it against EcoFlow's DELTA Pro Ultra with Smart Home Panel 2, and a couple compared it with two of Jackery's HomePower 3600 Plus at $3,099 against $2,999 for one 5000 Plus. On STS installs, one owner points out that 240V circuits need to be bonded in the app's voltage configuration.
