Product Q&A

Q:What is the maximum current capacity of the SRL500?

The SRL500 handles 500 Amps continuous at 12V and can withstand a surge of 700 Amps.

Q:How does the dual sensing feature work?

It allows charging both ways, enabling the auxiliary battery to be charged by external sources like solar panels, and the main battery to be topped up once the auxiliary reaches 13.2 volts.

Q:What are the voltage thresholds for connecting and disconnecting?

The smart relay connects the two batteries once the main battery reaches 13.2V and disconnects them when the system voltage drops below 12.7V.

Q:Does this relay cause a voltage drop to the second battery?

No, the microprocessor-controlled smart relay does not create a voltage drop to the second battery, unlike conventional isolators.

Q:What is included in the packaging for installation?

The package includes two 1/0AWG copper ring terminals and heat shrink tubing for easy installation.
