HIGH-QUALITY BATTERY ISOLATORS
Sonoma has been supplying generator manufacturers with our "Battery Isolator" since 1999. Initially designed for turbine starting applications, they are now also utilized for diesel generator and switch-gear applications.
We offer isolators from 80 amp up to 4000 amp models. To insure the integrity of your generator to start when needed, dual starting batteries combined with our Battery Isolators add another level of redundancy to your back-up systems. In normal operation, when the engine starts, current is pulled from both batteries to the engine starter (s) through the battery isolator.
Our custom blocking diode assembly isolates one battery from the other so a defective or weak cell in one battery will not affect the operation of the other. Since each battery is sized to start the engine by itself, the loss of one battery does not affect the starting sequence.
If you don't see a solution that fits your application needs, contact us. We'd be glad to assist you in providing solutions.
