Choose your superpower.

Wattsonic Li-LV Battery offers an option if you are looking for batteries to match your system. Approved by world leading inverters makes sure your batteries work well as soon as you plug them in without any more operations. Comprehensive battery design and considering protection function makes sure our battery can have a perfectly performance while a long life time.

The 5kWh wall mounted/free stand LiFePO4 battery module is an excellent choice for your system. No extra BMS needed, the battery can be paralleled to realize a bigger capacity up to 25kWh. Internal technology helps to save more energy and to extend the battery have longer life-time to 10000 cycles at 90%DOD.

Not enough capacity?
Maximum 5 models can be paralleled.
The total capacity can be up to 25 kWh.
Master-Slave address will be auto-set based on inner BMS.

Plug and Play

Based on Wattsonic standard parallel kits(shipped with product), you can easily finish your installment by using the accessory cables.

High compacity,
high compatibility

Approved by world leading inverters, the integrated BMS with the battert will automatically recognize the inverter communication protocol and match it after the battery is connected to an inverter.

Normally, battery capacity will be decresing during using. But Wattsonic put great efforts in slowing down the process.

Module level auto-balancing: While Charging: Charge the battery to the same level first, then continue to charge uniformly; while discharging, discharge the battery to the same level and the discharge it together.

Extend user care and experience to next level.Together with multi functions to make the battery more durable, Wattsonic battery can realize 10,000 cycles at 90% DOD and 1C/1C continual charger& discharge. We still has 10 years long standard warranty. Our after-sales person will gladly help you if you have any problems.

Frequently asked questions

There is a large power fluctuation on battery charge/discharge.

Check the following items:
1.Check if there is a fluctuation on load power;
2.Check if there is a fluctuation on PV power on Wattsonic Portal.If everything is ok but the problem persists, please contact Wattsonic local technical service center.
SOC changed after restart the system.

When restarting the system, SOC only depends on the battery voltage. After a whole charging and discharging process, SOC will be accurate.
