K2 Energy Pytes V5 48V Backup Battery FAQs
1. How much usable energy is there?
5.12kWh nominal, of which 4.86kWh is usable at 95% depth of discharge. That 95% figure is unusually high, so you get more out of this battery than most that quote 80%.
2. How long will it last?
Over 6,000 cycles at 95% depth of discharge, with round-trip efficiency at or above 95%. For a home backup battery cycling daily, that's many years of service.
3. What can I connect it to?
It communicates over CAN, RS485 and RS232, so it integrates with most compatible inverters. Ring us on 1300 902 361 with your inverter model and we'll confirm compatibility before you order.
4. What are the charge and discharge limits?
Recommended charge voltage is 56.5V at 50A, with 100A maximum charge. Discharge is 50A recommended, 100A maximum continuous, and 110A peak for 15 seconds.
