How to work

1. Saving bill with PV
In the daytime, the PV will power to the load and store the excess power in the batteries. In the evening, use the power from the batteries to power the load.

2. Ensure uninterrupted power supply
When there is no PV and the grid power failure, lithium battery will take the load, to ensure uninterrupted power supply as power system.
3. Peak-to-valley spread arbitrage
Storing capacity on batteries when tariffs low using battery capacity when tariffs peak. Save on peak rate costs



Applications


● Solar energy storage;           ● Wind energy storage;

1.How much solar battery storage do l need?
For a small household with monthly electricity consumption below 100 kWh, a 5 kWh lithium battery would suffice. f monthly consumption is around 300 kWh,a 10 kWh lithium battery would be suitable. For consumption around 500 kWh per month, a 20 kWh lithium battery would suffice. f monthly consumption is around 1000 kWh, a 50 kWh lithium battery would suffice. The specific situation also depends on factors such as daily electricity usage,availability of grid power, and consecutive rainy days.

2. Is it safe for indoor installation?
It depends on the voltage of the battery. If it's 12 V, then it's 1.2 kWh. If it's 48 V, then it's 4.8 kWh, and so on.

3.Are lithium ion batteries safe?
Absolutely. LiFePO₄ batteries are among the safest lithium battery chemistries. The system includes a built-in Battery Management System (BMS) for protection against overcharge, over-discharge, overheating, and short circuits. Additionally, it features an independent physical aerosol fire extinguisher for enhanced fire safety.

4.How many cells in a lithium ion battery?
It depends on the battery capacity. For conventional sizes like 5 kWh and 10 kWh,they are typically composed of 16 cells,each with a voltage of 3.2 V, connected in series.

5.How long can a solar battery power a house?
This depends on the capacity of the battery and the power of the household load.
