15.36kWh LiFePO4 Battery Pack 51.2V — Deep Cycle Solar Storage, 6000+ Cycles
15.36kWh LiFePO4 Battery Pack 51.2V — Deep Cycle Solar Storage, 6000+ Cycles
At 15.36 kWh this is the largest bank in the range — sized for whole-home backup rather than partial coverage. The 51.2 V architecture keeps current manageable at high power, which is why it pairs with larger hybrid inverters.
Where it fits best
- Whole-home backup covering lighting, refrigeration and air conditioning
- Large off-grid homes with evening-heavy load profiles
- Small commercial sites needing several hours of ride-through

Questions buyers ask
How long will it run my home?
Divide usable energy by your load. At 80 % depth of discharge, roughly 12 kWh usable supports about 1.5 kW of continuous draw for eight hours, or a lighter 750 W load for around sixteen hours.
Does it communicate with my inverter?
Yes. CAN, RS485 and RS232 ports allow closed-loop communication with compatible inverters, so the inverter reads the battery's own state of charge instead of estimating it.

Frequently Asked Questions
What is a LiFePO4 battery?
Lithium iron phosphate chemistry that offers long cycle life, thermal stability, and safe deep discharge compared with older battery types.
How long does it last?
LiFePO4 packs typically deliver thousands of charge cycles at 80% depth of discharge, which means years of daily use.
Can I expand capacity later?
Many IPV ESSA systems support parallel battery expansion; check the model manual for the maximum number of units.
Where should I install it?
In a ventilated, dry location away from direct heat and moisture, as with any electrical storage equipment.
