The 51.2V 280Ah Lithium Battery is a high-capacity LiFePO4 storage module for solar hybrid systems, rated for 8000 charge cycles with a 5-year warranty. It communicates over CAN/RS485, uses ultra-safe LFP cells, and can be paralleled up to 32 modules for large storage requirements.
What it is for. A hybrid solar inverter needs a battery to do its job without storage, a hybrid is just an expensive on-grid inverter. This is high-capacity storage, holding roughly 14kWh in a single module, for homes and premises that need to run substantial load after dark or ride through longer outages. Where the 100Ah module suits backing up essential circuits, the 280Ah is for whole-home overnight running or commercial backup, on its own or paralleled into a larger bank.
8000 cycles is the number that defines its value. Lithium iron phosphate replaced lead-acid in serious solar storage because of cycle life, and at 8000 cycles this module is rated to charge and discharge once a day for over twenty years before reaching end of rated life a third longer than the 100Ah's 6000-cycle rating. Over a system's lifetime, that cycle count is what determines real cost per unit of stored energy. A cheaper battery replaced several times is not cheaper.
Understand the 0.5C continuous rating before you size it. This module delivers 0.5C continuous power, meaning it supplies up to half its capacity per hour on sustained draw a higher instantaneous load than that should be spread across paralleled modules. The 100Ah module, by contrast, runs 1C. In practice this means the 280Ah is built for large stored energy delivered steadily, rather than a very high burst from a single unit. If your backup includes heavy simultaneous loads, our team will tell you whether one 280Ah, several in parallel, or a different configuration suits your draw this is exactly the kind of match that goes wrong when a battery is bought without matching it to the load.
Built safe and to scale. The ultra-safe LFP chemistry is the most thermally stable lithium type, chosen for storage precisely because of its safety margin. Multi-level protection guards against over-discharge and other fault conditions, and remote firmware upgrades with an original-firmware backup mean an upgrade cannot brick the unit a genuine reliability feature on a device meant to last two decades. You can parallel up to 32 modules, so a system can scale to very large storage without replacing existing units.
Sizing it to your system. One 280Ah module stores roughly 14kWh at nominal voltage enough to run a substantial share of a home overnight, depending on load. Whether you need one, several, or a smaller 100Ah unit depends entirely on what you are backing up and for how long. Tell our team your critical load and required backup duration, and we will size the bank against that rather than selling you the largest unit.
SolarClue is India's managed solar marketplace. Our team confirms this battery is compatible with your hybrid inverter, sizes the bank against your actual backup need, and coordinates installation through verified partners at 115kg this is a floor-mounted unit that needs proper siting, which we handle. If you are buying a hybrid inverter, we match the battery to it so the two work together correctly. You book with a token payment rather than the full amount upfront, and we handle warranty support afterwards.
