The BSLBATT Powerwall is a fully integrated battery energy storage system for residential or light commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, time-based control and backup.
In addition, the Powerwall's multi-protocol interface allows easy connection to any house or building. The compact design not only revolutionises market-leading energy density, but is also easy to install, enabling homeowners to quickly realise the benefits of reliable, clean power.
When you install the BSLBATT Powerwall it has many features including setting up any back-up circuits, configuring the software correctly and integrating it with solar and electricity meters. That's why it's important to choose BSLBATT's Powerwall installation program. From installation to use, BSLBATT will provide thorough support with a guided service, so we have oversight of the entire process, including quality.
 Safety BSLBATT equips all battery series with safety components, including the BMS (Battery Management System), to protect the battery from short circuits and to control the temperature and pressure of the battery. |  Energy Density 150 watt-hours of electricity can be stored in a 1 kg lithium-ion battery, which is three times more energy dense than a lead-acid battery. Lithium batteries have a greater storage capacity even in a smaller space. |
In contrast to lead-acid batteries, lithium batteries do not require additional ventilation and regular acid refills. Plug and Play is supported regardless of the time and place of use. |
