Balancell P27 14.4kWh

The Balancell Residential and Small Business
battery is an intelligent and powerful 52V energy
storage system. The battery is available in a range
of capacities, from 10.7kWh to 28.8kWh and is
easy to install for use as a backup during power
outages or with solar – enabling you to quickly
realise the benefits of reliable
and clean energy.

Discharge Limits – (Voltage & Current)BatteryProtectionNotes
Continuous Discharge current270A 1C continuous
Surge Discharge Current – 30 seconds400A 3C transient. Typically repeated for every lift or peak load.
Electronic Current trip limit – analogue 550AIf the electronic current limit option is enabled – Note 1*
Electronic trip Retry time – analogue Time taken after current trip to retry connection
Pre-Charge current limit – Note 1* 550AAutomatically provided if electronic current limit is enabled
Electronic Overload – Digital  Optional with either, I²t , max current, or Custom profiles
Internal Battery Fuse400A I²t = 610 000 A
Minimum battery voltage47.2V Battery will cutout here, regardless of indicated SOC
ABSOLUTE Minimum Battery Voltage 43.4VInternal electronics Disabled! Please see battery protection.
Note 1*. Electronic current limit is optional and adjustable between 500-1000A. It will act as a automatic pre-charge for connection to inverters. For motive applications, in particular old lead machines, pre-charge or current limit prevents startup, and not desirable.
Charge Limits – (and charger settings)
Maximum Continuous Charging Current200APreferred range is 130A to 200A, set for constant current CC.
End of Charge voltage56V55.6V to 56.0V max set as endpoint CV voltage
Balancing charge voltage or current56.2V56.0V-56.3V OR charge at constant current (CC) of 400mA
Charger voltage range48VCharger voltage must be within normal 48V limits.
Battery maximum voltage self cut out56.4VBattery will cutout, preventing further charging, NOTE 3*.
Peak transient charger voltage100V*Peak transient voltage after battery self disconnects
Charger Lead Inductive Energy75JNOTE 4*. However, Typical 2m length lead installations are of no concern.

NOTE 3*. If battery self cuts out from over voltage it will still be available for discharge through reverse diode.

NOTE 4*. This is the maximum charger lead Inductive energy battery cutout can absorb ( 1/2 I²L < 75J ).
