We are trialling a "load shifting UPS" project. Load shifting means charging batteries during the off-peak period at night when grid electricity is low cost. Then power is consumed during the day from the batteries via an inverter.
It is effectively an Uninterruptable Power Supply which additionally supplies off-peak electricity. In effect it removes the requirement for high maintenance back up generators.
This system will test the reliability of the CALB batteries over a period of continuous deep cycles (50-70% DOD per day). In the picture is a 5kW inverter/charger and 16 x CALB180FI cells using the EV Power battery management system. Approximately 9 kilowatt hours of storage. The net energy cost saving is about $1.80 per day.
This is well suited to facilities that require uninterrupted 240V power and it offers the significant advantage of electricity always being supplied at off-peak rates.
As usual EV Power leads the way on practical usage of LFP batteries.
