Connect the controller by following the steps described below to avoid installation
faults.
Observe the following connection sequence when installing the system:
1. Connect the battery to the charge controller – plus and minus.
2. Connect the photovoltaic modules to the charge controller – plus and minus.
3. Connect the load to the charge controller – plus and minus.
Follow the reverse procedure when uninstalling!
Additionally, to avoid any voltage on the wires, first connect the wire to the
controller, then to the battery, photovoltaic modules. But for load, first connect
the wire to the load, then to the controller.
Recommended minimum wire size: 4 mm

;
Make sure the wire length between battery and controller is as short as possible.
Be aware that all positive connections of ECO controller are common and
therefore have the same electrical potential. If any grounding is required, always
do this on the positive wire.
