The main challenges for Batteries
3 Outperforming Solutions
Exposure Typical Problems Solutions
Battery Performance Low cost batteries have extremely low performance at high temperature and/or in cycling conditions. (typically ¼)
Select right batteries depending on temperature and grid conditions .
High Ambient Temperature Both Battery design life and Cycle life are reduced (Typ 50% at 30-35C)
Temp Controlled Storage and Installation in Cooling Cabinet
Repeated Power Outages Battery does not have time to recharge due to Repeated Cycles.State of Charge will decline and Batteries will dry out and fail.
Use New Battery can fast recharge or operate in partial state of charge
OverCharge Incorrect rectifer settings (ie Boost) can significantly shorten battery life.Battery is overheated (risk of Thermal runaway/ leaking) Design life reduced to 1/5.
Review Rectifier settings or use Float Voltage recharge
Why are Batteries failing so early in many countries ?
