If you don't like blackouts, you may need a home battery backup system to provide power. Maybe you can use an air-cooled home generator powered by gasoline or propane to keep power for a few hours, or you can buy a more expensive liquid-cooled generator to keep power for longer. But if you live in an area where there are frequent power outages, the best way is to spend a small amount of money installing a battery backup for home, instead of spending a lot of money on a generator. Not only will it save you costs, but it will also provide prompt power and long-term endurance in the event of a power outage. Therefore, we will arrange the products for reference to meet your needs.

How to Choose the Best Battery Backup for Home?

Charging and discharging power

The charging and discharging power you need for your electricity storage unit depends on the consumers you want to supply with it. 

Storage capacity or nominal capacity

According to the demand for power to choose different capacities of home backup batteries.

Charging cycles

The service life of a battery storage unit is largely defined by the number of charge cycles.

Efficiency of residential storage system

Under optimal conditions, the efficiency of electricity storage systems is 90& to 98 %, which is very efficient.

Charging and discharging power of the home battery backup system

Choosing a home backup battery should consider charging and discharging power.  The greater the charging power, the faster the charging, the higher the discharge power, and the greater the power consumption.

Conclusion

Home backup battery system provides power by storing solar energy, which partly solves the problem of power shortage to some extent, and also reduces the cost of power consumption and replacement, so there is a good choice to use home backup battery in any area.
