20 Kwh Battery LiFePo4 Lithium Battery 48V 51.2V 400Ah For Solar Energy Storage UPS

Specification

Charging mode

1. Solar charging only: photovoltaic charging only, without starting mains charging, the most energy-saving way 2. Photovoltaic priority: Photovoltaic priority charging, starting mains charging only when photovoltaic fails.
3. commercial power priority: commercial power gives priority to charging, and photovoltaic
charging is started only when commercial power is invalid.
4. Hybrid charging: Hybrid charging of photovoltaic and commercial power, giving priority to
photovoltaic, commercial power supplement, the fastest way.

Output way

1. Photovoltaic priority: Photovoltaic+battery power supply, maximizing the use
of solar energy while maintaining battery energy.
2. commercial power priority: commercial power is given priority, and uninterrupted.
3. backup UPS is started when commercial power is invalid.
Inverter priority: maximize the use of DC power.

Q4: Are your factory or trading company?
A4: We are proffesional Lifepo4 cells and packs manufacturer with our own factory and brand BENERGY. We provide all kinds of OEM/ODM services for clients around globe.

Q5.What is your warranty?
A5:We offer 2 -5 years warranty for all our battery pack.we ensure at least 3000 cycle life for the LiFePO4 battery pack, which means,after 3000@80% DOD,there will still around 80% capacityt left.You can use it for at least 5 years for normal 1 time charge and discharge everyday.

Q6.Can we put 48V LiFePO4 battery pack in parallel or series by ourself?
A6:Yes. The battery can be put in parallel by customers. But there are few tips we need to pay attention:
1> Make sure the voltage of each battery are same before put inparallel. If they are not same, charge them to the same rate;
2> Do not put discharged battery and undischarged battery in parallel. This may reduce the capacity of the whole battery pack;
3> Do not put the 12V batteries in series.
4> If you are not professional in parallel batteries, please don't handle the battery by yourself. It may cause danger and hurt the cycle life of battery;

5> If you want to make a higher capacity battery pack, like 48V 200Ah, please order 48V 200AH directly. The cost for one 48V 200AH is lower than two 48V 100AH pack. To charge or discharge one 48V 200Ah directly is better than to charge or discharge two 48V 100AH packs, cycle life longer, safer.
