Home storage batteries

Whether in conjunction with a solar module or as a standalone, grid-connected device, home energy storage can reduce a house's dependence on the power grid, giving homeowners more control over their electricity consumption and reducing the climate impact of their energy use.

Most home energy storage systems use deep-cycle battery systems with 12, 24, or 48 volts. These can often be connected in series and parallel to create a higher-capacity energy storage system. For longer runtime, lower maintenance costs, and extended lifespan, we recommend upgrading to lithium iron phosphate (LiFePO4) batteries, which are perfect for your home power needs.

We recommend using a LiFePO4 lithium battery charger to charge these batteries, as their charging requirements differ from those of lead-acid batteries.

The following are the charging alternatives for Power Queen LiFePO4 lithium batteries for home energy storage.

(1) AC-DC lithium battery charger: To charge the battery safely, choose a charger with the appropriate charging voltage.

(2) Solar panels: If you are using solar panels, you must connect a solar charge controller to ensure proper charging.

(3) Alternator or generator:

If your alternator or generator has a DC output, a DC charger is required to connect the battery.

2. If your alternator or generator has an AC output, use a compatible battery charger, as specified in the product documentation, to properly connect the battery and generator.

A typical home energy system includes:
(1) Solar panels (optional): for generating electricity

(2) MPPT solar charge controller: optimizes the efficiency of solar charging

(3) Energy storage batteries (e.g. LiFePO4): for energy storage

(4) Inverter (hybrid or off-grid): converts direct current from the battery into alternating current for household use

(5) Monitoring system/APP: Remote monitoring of electricity generation and consumption

Yes, but the prerequisite is that the system is designed to cover the entire load demand of the household, including emergency power supply at night and during bad weather. Recommended configuration:

(1) Photovoltaic system with sufficient capacity

(2) Large capacity battery (e.g. 10kWh or more)

(3) High-performance off-grid inverter
However, more and more households are opting for the hybrid mode of grid connection and energy storage to ensure the stability of the power supply.
