Off-Grid Lead Acid Battery Replacement – The Ojai Foundation
SIMPLIPHI POWER replaced 24 toxic lead acid batteries with 8 efficient, clean and enduring OES 2.6 energy storage and management units at The Ojai Foundation.
The power capacity increased while the footprint decreased, eliminating maintenance, toxic off-gassing and losses typical of lead acid batteries. The Ojai Foundation wanted to demonstrate a new model of power generation, transmission and distribution that was off-grid, local and sustainable. SimpliPhi Power easily achieved the Foundation’s goal of having reliable power 24/7 using solar power as its sole power source.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
