Step1:
Locate a suitable location to install Solar Regulator away from
direct sunlight and rain. For best wireless performance, situate
Solar Regulator within 100ft of Inverters/Battery Commanders and
position the antennas away from dense materials such as
concrete, brick, tile, and metal. Antenna extension wires are
available for purchase if you choose to locate the antennas away
from Solar Regulator housing for improved wireless performance.
Step2:
Install the split core transformers on your overhead wires. For
underground fed wires, install inside your electrical panel.
Attach one transformer on HOT Phase A and one transformer
on HOT Phase B. *For single phase, the 2nd transformer is
not used and not connected to Solar Regulator.
Each transformer can clamp onto a wire up to 16mm
diameter. If the included transformers do not
fi
t, 24mm
diameter transformers are available for purchase from
www.plxdevices.com tap Legion Solar or search for Split Core
in the search bar.
Split core transformers are not waterproof. If installing on
overhead wires, wrap transformers with moisture sealing
electrical tape available at your local hardware store in the
electrical section. Use 3M 2228 or equivalent.
Step3:
Connect the split core transformers to Solar Regulator. Any transformer
can be connected to any connector. Direction does not matter at this time.
Once system calibration has been performed via Legion Solar App. Do NOT
reverse connector positions, otherwise re-calibration must be performed.
Note: If you choose to locate Solar Regulator away from the distribution
panel such as to optimize wireless range with Inverters and Battery
Commanders, split core transformer wires can be cut and extended up to
100ft/ea. Use AWG22 or thicker wires to extend the length and use
moisture barrier tape to ensure a waterproof seal.
