DescriptionMonoLith 51.2v 163Ah — 48v Energy Storage for Solar and Off-Grid Home SystemsThe MonoLith 51.2v 163Ah Lithium Battery opens up a new category for PowerPaul® Australia — purpose-built 48v energy storage for solar systems, home batteries and large-scale off-grid installations. With 163 ampere-hours of capacity using premium CALB cells and a 200A BMS, the MonoLith 48v delivers the high-voltage efficiency that modern solar inverters and off-grid systems are designed to work with.A 48v system dramatically reduces current at any given power level, resulting in lower losses, thinner cabling requirements and more efficient energy transfer between your solar array, battery bank and inverter.Key SpecificationsNominal voltage: 51.2vCapacity: 163Ah (CALB cells)BMS: 200A with Bluetooth connectivityChemistry: LiFePO4 (Lithium Iron Phosphate)Case: Identical across all MonoLith models — standardised heavy-duty case designWarranty: 10-year warrantyParallel ready: 2 sets of positive and negative connections. Built with CALB CellsThe MonoLith 51.2v features CALB cells — a trusted name in lithium cell manufacturing known for quality and longevity. CALB cells are widely used in energy storage applications and deliver consistent performance and reliability across thousands of cycles.200A BMS with BluetoothThe integrated 200A BMS provides comprehensive protection including over/under voltage protection, over current protection and temperature monitoring. Connect via Bluetooth for real-time monitoring using apps available for iPhone and Android — ideal for keeping an eye on your home battery system or solar installation from inside the house.Who Is the MonoLith 48v For?The MonoLith 51.2v 163Ah is designed for 48v solar systems, home battery storage, off-grid cabins and properties, and large-scale energy installations. It’s compatible with popular 48v hybrid and off-grid inverters and is an excellent choice for anyone looking to store solar energy for overnight use, backup power or complete energy independence. If you’re building or upgrading a solar system and your inverter supports 48v battery input, the MonoLith 48v is built for exactly that purpose.The case design suits any setup. It can be mounted under a caravan attached to the chassis rails (you will need to fabricate suitable mounts), under a bed or bench seat, or even upright against a wall. It comes with a venting option as standard, to help installations comply with Australian Standards.Power Connections are supplied with the battery using waterproof Amphenol type crimp connectors. The 2 sets of parallel connections can be used to spread the load, or to help with adding more batteries or daisy chain arrangement. Fittings for venting or sealing are also supplied.Every unit is calibrated, load-tested and fully cycled at least twice. Our electronics specialists are available for direct customer support and tailored advice on integrating the MonoLith into your solar or off-grid system.Contact PowerPaul® Australia today to learn more about the MonoLith 51.2v 170Ah Lithium Battery.SpecificationsRated Capacity163 Ah lithium battery (approx. 8,345.6Wh)BMSTo be confirmedDimensions730mm L, 285mm W, 195mm HWeight67kgVoltage51.2v NominalBMS currentTo be confirmed (different BMS model than 12V/24V variants).Connecting to other batteriesParallel connection to other identical batteries is allowed (must be same voltage first).
