Our wall mount batteries are IP65 rated, supporting all weather conditions for indoor or outdoor installation. However, for extreme weather in different regions, we recommend installing the battery in a cool, dry room without a strong magnetic field to better preserve battery performance.

10 to 15 hours. Usually, a small and medium-sized family consumes 0.5-0.8kwh of electricity per hour, which means that a wall mount battery of 8.8kwh can support electricity consumption for 10-17 hours.

Harveypower wall battery for solar all has 20-year design life, a minimum of 6000 cycles is sufficient to provide one cycle per day for 16 years. Good maintenance can further prolong its service life.

Mainly depends on the total power consumption of the household. Assuming that the power consumption of all electrical equipment in a family is 10kwh a day, A 3.2V 200Ah battery can provide 0.64KWH power. Then a total of 10/0.64≈16 batteries are needed. Contact us, choose battery specifications (100ah,161ah,172ah,200ah,228ah,300ah,345ah,400ah,456ah) according to different needs, and customize your wall mount battery capacity.

Best overall off-grid battery for homes: 48V wall mount lithium battery. Advantages: Save space & Long lifetime & high safety. Best value off-grid battery for homes: Harveypower 3W512100. Advantages: CATL battery cells(6000+ cycles, 20year design life) & BMS & LED Screen Best off-grid battery for vacation homes: Harveypower R512228. Advantages: 1-30Kwh capacity free expansion, easy to assemble.

First fix the back bracket on the wall with 6 screws, and then snap the back groove of the wall mount battery into the corresponding groove of the bracket.

Exact pricing will vary based on which battery model you choose and how many of them you need to power your home. For example, the capacity difference between lifepo4 battery 200ah and lifepo4 battery 100ah is 2 times, but the price difference is usually about 1.8 times. However, an average sized home battery backup system typically costs between $10,000 and $18,000 to run

A lithium battery can easily be stored for a year. Make sure you maintain a 50%-80% charge when storing, and by recharging every 3-6 months, you will be able to store for much longer. Know more about how to store your battery.

For the cost per kilowatt hour of storage and the long-term energy savings, storage batteries are very cost-effective.

About 8-12 Hours, the length of the power supply is related to the total power used by the household.

The parallel connection is better, the parallel voltage remains unchanged, and capacity increases. The voltage is higher current, heat is faster (the battery also has resistance), so the life is short, parallel connection through the two batteries is independent of the current, will not affect the life.

You can have flexible parallel series connections through multiple battery packs to meet different voltage and capacity requirements, and save space.
