The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged).
This intelligent battery monitoring prevents unwanted switching.
Some battery combiners will disconnect a battery in case of a short but high amperage load.
A battery combiner also may fail to connect a large but discharged battery bank because the DC voltage immediately drops below the disengage value once the batteries are connected.
The software of the Cyrix-i does more than simply connect and disconnect based on battery voltage and with a fixed time delay.
The Cyrix-i looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period of time.
The time delay depends on the voltage deviation from the trend.
