HOST RS485 Parallel Charge Connection Cable for Charge Controller User Manual

Expand the charging current for charging your battery bank system by connecting two charge controllers using the RS485 Parallel Charge Connection Cable.
No need to upgrade to a controller with a higher amperage parameter. Connect two controllers in parallel to achieve the charging current you require.

Works with HQST MPPT Charge Controllers Series with an RS485 communication port: HCC-20MPPTN, HCC-40MPPTN, HCC60HTR.
It’s not compatible with other brands’ controllers and PWM controllers.
If you’re not sure about the compatibility of your controller, please feel free to contact the seller directly or send us an email at sales@myhqsolar.com

First, connect the battery bank to two charge controllers that you want to connect in parallel for expanding charging current (both controllers can be connected to an independent PV array system).
Then, link these two controllers using this RS485 parallel charge connection cable.
Both controllers must be set the same and right battery bank system voltage parameter.

Note:

It supports connecting two controllers with different amperage parameters, such as 20A + 40A, 20A+ 60A, or 40A + 60A.
Please remember to set the controllers with the same battery charge voltage parameter before connecting the PV arrays to the controllers. Or you will damage the battery bank system.
When using parallel charge connection cable, two controllers only can be connected to ONE battery bank system.

The parallel charge connection function of the controller is disabled by default.
