How Does Sump Pump Battery Backup Work?

Before investing in a battery backup sump pump system, it’s crucial to understand its working. Before we dig deep, let us answer the commonly asked question — how does a sump pump battery backup work?

The sump pump battery backup system uses heavy-duty batteries to provide power. The device is connected to the pump sentry, which connects to a 12V marine battery or AC utility power. The 12V marine battery stores the charge when electricity is available and supplies it to the sump pump during power outages.

The sump pump battery backup is like a two-stage system. The sump pump uses your home’s power when electricity is available. When there is a power cut, the battery backup starts functioning and supplies electricity to the sump pump.

How does a Jackery portable power station work as a sump pump backup battery?

Unlike typical sump pump battery backup systems, Jackery Portable Power Station charges sump pumps using safe and clean solar power. The solar panels are connected to the power station using the solar charging cable. While solar panels convert sunlight into electricity, the portable power station supplies electricity to devices like sump pumps and ensures they are working with or without electricity.
