PowerHub is the transfer switch panel that sits between the home's meter, the loads to protect and one or more Zendure inverters it's connected to with dedicated signal cables: it distributes incoming power, measures in real time how much the connected appliances are drawing, and decides whether to let the grid through or isolate it. It doesn't generate or store energy on its own: that comes from the inverters and batteries it's connected to.
When the grid goes down, it isolates the home within milliseconds to keep the system from feeding current into a faulty line, then signals the connected inverters to switch to island mode and keep powering the critical loads with whatever sun and battery are available. When the grid stabilizes again, it switches back to grid-connected mode without manual action; there's also a manual bypass for cases where the panel itself needs to be isolated for maintenance.
It's installed on a wall by a licensed electrician, not by whoever buys it: the manual requires compliance with local regulations and forbids installation by unqualified personnel. It also supports connecting an EV charger to the same system, giving priority to whoever needs it at a given moment through the app.
It answers the question of anyone who already has a Zendure storage system and wants the battery's energy, during a blackout, to reach the whole home or a chosen branch of the system, not just a single outlet: its role is that of a smart circuit breaker, not a source of energy.
