This is a fully automatic UPS. It can power your router or ONU using solar power or a 12V battery.
The UPS features fully automatic cutoff. It runs directly from the router/ONU charger when electricity is available, and automatically connects to the battery during power outages. The UPS has two modes: UPS and IPS. Keep the switch on for IPS mode, which will reset the router during power outages. Keep the switch off for UPS mode, and the router will not reset during power outages.
