Hello friends

I’ve had lead acid batteries before for years and I’m planning on going with a new home backup power system.

I learned that the lithium iron phosphate battery on the market has replaced the lead-acid battery, and it has its own BMS, which has a longer life and is more environmentally friendly. It has overvoltage, overcurrent, short circuit, overcharge and overdischarge functions. I want to DIY a 48V home backup power supply, what is there? How can it be achieved? Is the direct purchase of 48V batteries? Or is it implemented in series and parallel?

[unknown] Hello, for 48V home backup power, if your budget is sufficient, and your home has enough space, you can choose a rack-mounted all-in-one battery pack, or if you don’t have enough budget, you can also connect in series Multiple 12V or 24V units can get a 48V energy storage system, but the premise is that you have enough space to place these batteries, and then there is a wall-mounted home energy storage system, such as powerwall, which does not take up space, is more intelligent, and has its own bms . Secondly, you need to consider the configuration capacity of your home backup power supply. You need to calculate according to the daily load of your home and configure the battery specifications with sufficient capacity for you.If you have any other questions, please contact us at info@lithiumbatterytech.com

You can also choose a single 48V battery in parallel or choose an integrated home energy storage system
